@FMJxSKATER actually the 5.56 has a thicker case wall... due to the higher pressure in the 5.56 NATO round. This is why you can technically "run" .223 in a 5.56 gun (might need some gas adjustments) but should NOT run 5.56 in a .223
Just outta curiosity, why did you choose the ACR? I think it has the cool factor, but very expensive and fairly new to the civilian market with other proven systems, with a smaller price tag. I'm not disagreeing with your choice, just trying to understand what I am missing? Thanks
Sounds like you gunsmith is a dumb ass...That is exactly what it was designed to shoot....that and 6.8 spec....The Masada wad designed to shoot 7.62 as well...
disregard my comments on last video didnt notice this one. that is crazy that they would only make it to fire .223 and not have it a nato round. have you tried taking it to a "highly recomended" gunsmith not affiliated with bushmaster and getting there opinion. and is this a pds or gas. ie do you have a nob to adjust blowback
wow sorry man you jsut got a bad one. everywhere i go people say they run hundreds of rounds through the ACR without any cleaning or lubing and have no problems even with 5.56. including some top youtube guys.
Dude Im sorry, Your gun is a pile of dung! I live in Rio Rancho and I'll let ya shoot a real gun, My Mini-14 & Mini-30! ... NEVER A problem, Check out nutinfancy Mini-14 against the world. I've owned Rugers for 30 years they are the BEST!! Way too many parts in your gun! Parts = Problems ... Plain & Simple!
@kentawannabe multiple calibres, not necessarily every power round etc. its an awesome design, just bushmaster screwed up the manufacturing of it, skimped quality etc.
i would be bitchy too if i paid 2k for a gun thats fubar in your hands. 4 months, man...that would be forever for me. thank you. im getting a scar before this for sure now.
Interesting, from what I saw in the first video I could have sworn it was a bolt travel obstruction of some kind causing a LACK of recoil impulse in the bolt. On video its a bit difficult to see but it looks like that bolt is about crawling back like theres burnt lube or something caked on to the bearing rails. I would have diagnosed a lack of gas pressure yet I guess I would have been wrong.
hey jdelulsa: what kind of magazine are you using? cause i heard that if you use the m4 mags as opposed to the p-mags, then it causes problems. supposedly, the m4 mags get pushed to far up the mag-well, so you either have to pull it down a lil bit before firing, or use p-mags instead. (but I am no expert, just thought id give you my 2 cents)
I don't understand why Magpul\ Bushmaster would not have designed this gun for the 5.56 so as to be prepared for the possible military market applications??? also you would think if they designed it for the 5.56 that the gun would handle anything the .223 could throw at it. very strange.
@TheOmniscientSpanner It's not the bolt and barrel. After working with Bushmaster for 4 months it was determined that the 5.56 cartridge was over-pressuring the gas regulator and causing the bolt to cycle too violently which resulted it the outgoing brass being caught and pulled back into the feed ramps. Just not enough time to eject properly. Modifications were made to the gas regulator and op-rod spring and the problem has been fixed.
They did design the civilian version for .223 vecause it is more available to the public, what you are thinking of though is the modified milspec version which had changes made to support the 5.56 for military purposes
223 and 556 are not the same they re very similar but not the same pressure makes a huge difference gun smith is not an idiot the Bushemaster ACR was built around the 223 the remington ACR was built around the 556.
@redgunner132 whether or not the .223 and the 5.56 has different specs, it shouldn't be a problem on a gun marked for 5.56. I can understand if the OP tried to fire 5.56 thru a .223 marked only gun but this is pure BS. If is true what Bushy told the OP, they need to restamp their fucking guns to read .223 only. I would be pissed if I spend all this money on a rifle and can't shoot the round that it says its meant for.
The pressure difference is only based on what ammunition you buy. If you can get your hands on European rounds, which create more pressure when fired then this could be argued. Since the European standard to what firearms shoot and can take to shoot are more similar to NATO standards than the US civilian markets. If you buy American ammo which says .223 Rem, keep in mind that the 5.56x45mm is the same thing. That is just the metric conversion. Where as 5.56x45mm NATO is different.
IT CANNOT FIRE 7.62 from the same barrel or bolt they only have it in the 223 and 6.8 models. Just because you play call of duty doesnt make you a weapons expert. Also this gun is a rip off.
2.8k for a non-chrome lined barrel heavy rifle is retarded.
personally the Mk16, MR556, and the LWRC M6A2, M6A3 are way better piston guns and they have crome lined barrels!
doesnt fire 5.56 thats weird . maybe the smith at bushmaster was a new guy. lol these guns even show on their website that they are meant to fire 5.56. also i heard something about a recall or somehting like that??? maybe now they are all fine.
Hey Guys, I used to be into aircraft and all that stuff yet now I'm gaining an interest in Rifles especially after the first time I shot a gun (it was a .22 Cal but better than nothing) could anybody send me some links or videos that would help me get familiar with the round calibers, parts of the rifle, ranges, and all the fancy stuff they give you along with the name of the gun? Thanks (I don't even know what ACR means, but it looks like a beautiful gun)
@killbilly4545 I am not sure if they have fixed the problem. I have shot about 500 rounds through mine since the "fix" without any problems so maybe it is taken care of.
@jmank871 Actually, they are not the same. Dimension wise, they are about the same, but the 5.56 NATO, or m3 ball, shoots at a much higher pressure, which leads to more wear and tear, and more problems as a whole for a gun.
first off i didnt read all the comments so sorry if this has been said. extraction is when the casing is pulled from the chamber. ejecting is when the casing is flung out the ejection port. from what i see in your videos its a ejection problem not an extracting problem. on a side note. that sucks your having problems with your rifle im not getting one. ill stick with my m4 i built.
Bushy was full of crap when they told you that. Quite honestly that is entirely unacceptable to pay that much for a rifle only to be talked down to by the company that sold it to you.
@ARCHIE2480 They are, almost. There is a differencies in the throat of the chamber and freebore. Some people say that 5,56NATO is like loose .223 rem chamber. It allows higher chamber pressure. 5,56 fired from .223 chamber usually causes problems with extraction, but can actually be dangerous too.
Most AR rifles fire .223 as a general rule of thumb, as they are like the dumbed down versions of M-16's or M4's so i would assume the same about the ACR, but considering the price and quality, you think you could have adjustments on the gas system for .223 AND 5.56....
It could have been worse, you could have bought a SIG 556 like I did and had to send it to SIG 4 times. They told me with a 1-7 twist I wasn't supposed to fire 62gr NATO ammo in a 1-7 twist. They are about as dumb as a pile of rocks.
@mattpkp Actually, civilian version of Bushmaster ACR uses .223. 223 has lower chamber pressure than 556 - so if there is a higher pressure in the chamber it will suck back the empty shell. This is true for all Bushmaster ACR manufactured by Remington - the hammer that regulates piston has different size of pressure release for 223. Thus, DO CONFIRM WITH THE MANUFACTURER WHETHER YOUR ACR REQUIRES 556 or 223! (Remington wants to sell more 223 bullets :( )
@MasterBlasterMusic It's the other way around. Mil Spec barrels are 1:7 twist because this helps to stabalize heavier bullets. The folks over seas have found out the the 55 grain bullet rarely stops somebody on the "first try". No so with the 77 grain Seirra Matchking bullet (Mk 262) which has way more first shot kills. It will not fire accurately from a 1:9 twist barrel. Most civilain AR's sold in the US are 1:9 because is adequate for the 55 gr .223 remington round with is uber avaliable
i thought that .223 and 556 were supposed to be basically the same, with only minor difference? shouldnt they both work in a gun chambered for either? im gona try to research more i ll let you know if i find anything
@LotusKnives Did you see the comments of the two pinheads who posted just prior? According to them, niksknicks and blitzoo43, there is no difference between 5.43 NATO and .223 Remington, that I am a retard for believing that there was a difference, and that I am naive for thinking that it made any sort of difference at all in the performance of the rifle.
@jdeluisa yea they probably know nothing of the higher chamber pressures produced from a 5.56 vs .223, it makes sense that the ACR wouldn't handle it though, since it is a civilian gun, they figure people are shooting 100% civilian rounds
@jdeluisa yea they probably know nothing of the higher chamber pressures produced from a 5.56 vs .223, it makes sense that the ACR wouldn't handle it though, since it is a civilian gun, they figure people are shooting 100% civilian rounds, the higher chamber pressure may cause the bolt to cycle faster not giving the brass enough time to completely leave the gun
@niksknicks I think your comment should stay up so I will repost it. It is interesting to me that you and Blitz post something then take it down so other people cant read it.
@niksknicks I can't believe you're actually this naive. You justify your "differences" between a 5.56 NATO and a .223 Remington with "AR15.com." So I went and took a look at his supposed authority on the ACR and what was it? It's a friggin forum! LOL! I actually started cracking up out loud it was so funny. This just proves my point that you messed up your gun, got hustled, and now want a phantom answer for it. Oh btw, the ACR is the best rifle I've ever shot. When i get a camera, I'll show you.
@niksknicks The source I quoted is directly one of the customer service managers at Bushmaster Inc. in response to these videos. While it might be a forum, there are a lot of knowledgeable people on it. BTW, when you get a camera, why don't you make a video.
Wow dude, You really got hustled...a .556 NATO is the same as a .223! Maybe you should actually listen to Blitz...he sounds like he knows what he's talking about dude. I would laugh at you but I actually feel bad for you.
@niksknicks From Bushmaster as found on ar15.com, "The failure of 5.56 rounds in ACRs is beng looked into very seriously by the engineering dept. at BFI. The problem will be corrected and customers will be taken care of. For the record the subject rifle was test fired 150 rounds without a single malfunction before it was returned to the customer. The problem was it was fired with .223 Remington ammo which works fine and we are having trouble with 5.56 NATO ammo.
@niksknicks continued, "It was not listed in the paperwork the first time it was returned what kind of ammo was being used. Unfortunately 95% of the time all of the ammo on hand at BFI is .223 and not 5.56mm. This will obviously have to be changed here in the future."
@niksknicks and continued, "Again, on behalf of BFI my apologies for all of the confusion and frusteration. I don't come to AR15.com very often, but I'm hoping at least some of you believe that we really do care. We're dealing with a lot right now. Please be patient with us. Thank you all."
Respond to this video... Blitzoo43 is an idiot. There are several differences between 5.56 and .223. Higher pressures and different leede. There are reasons the military uses 5.56. It's frustrating that there are so many people on youtube who are more than willing to make negative comments when they don't know what the hell they are talking about. It's even worse when they don't have any videos of their own so they are unable to "put their money where their mouth is" so to speak.
@jdeluisa there is not a big enough difference that would do any sort of damage rifle. just admit ripped off. theres a reason most 5.56 ammo has / .223 on it and most .223 ammo has / 5.56 on it. one measurement is metric and the other is standard. o wait i forgot your retarded.... that means one is millimeter and the other is inches.
@Blitz0043 Did you read any of the direct comments from the engineers at bushmaster I posted above? There is a difference in the pressures and the chamber leede between the two calipers. There have been damaged receivers. NATO specification allows a higher chamber pressure. NATO EPVAT test barrels made for 5.56 mm NATO measure chamber pressure at the case mouth, as opposed to the location used by the United States civil standards organization SAAMI
@Blitz0043 The 5.56 mm NATO chambering, known as a NATO or mil-spec chamber, has a longer leade, which is the distance between the mouth of the cartridge and the point at which the rifling engages the bullet. The .223 Remington chambering, known as SAAMI chamber, is allowed to have a shorter leade, and is only required to be proof tested to the lower SAAMI chamber pressure. To address these issues, various proprietary chambers exist, such as the Wylde chamber (Rock River Arms)
Respond to this video...Using commercial .223 Remington cartridges in a 5.56 mm NATO chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223 Remington chambered gun due to the longer leade.[14] Using 5.56 mm NATO mil-spec cartridges (such as the M855) in a .223 Remington chambered rifle can lead to excessive wear and stress on the rifle and even be unsafe, and SAAMI recommends against the practice.
Respond to this video...Obviously the smith at Bushmaster was full of shit. That was the whole point of the video. And it's obvious that the ACR is not feeding 5.56 well and it's not just my rifle. They did have to replace my gas block, regulator, extractor spring and recoil spring and I'm still waiting for them to send it back. Did you ever consider there might actually be a problem with the design or their quality control?
@Blitz0043 You are in college? Good luck with that - Hopefully they will teach you how to research and to have a little respect for people who's opinions differ from your own
@Blitz0043 Saw the post you deleted where you state, "lol this is rediculous... i fire 5.56 natos in my ACR and wait.... 5.56 is a .223 DUH! you got played."
DUH? Maybe you should look into this a bit before you make a stupid comment.
Not a stupid comment considering that the only difference is the amount of brass, and one has a slight more powder. I deleted my comment because I didnt ant you to seem dumber than you already look. I own an ACR and I can even use junk ammo without any worry of jamming. SO whatever you did to you rifle makes you an idiot.
@Blitz0043 Well, there is a little bit more to it than that - maybe you should look it up and enlighten us all. BTW - I noticed you didn't have any videos of your own to show? It's pretty easy to sit back and direct stupid comments as others when you don't have anything of your own to show. Do you really own an ACR or is it some sort of airsoft knock off/Modern Combat wet dream?
@jdeluisa LMAO at least I wasn't to cheap to upgrade to the enhanced version. 5.56 mm or .223 inch. Don't pose as post military than accuse me of not knowing what I'm talking about. I didn't break my gun, and I'm sure that I've put more rounds down range. Talk to me when you know what your talking about. I'll make a video of me firing my acr enhanced and post it when I'm not at college.
thanks for the info. man, i was in the market for the ACR but hearing too many negitives things about it. going to spending real money on a real guns with good reputation LWRC not bushmaster
Well what I don't understand is on Bushmaster's website, in the F.A.Q. section, it says all Bushmaster rifles are chambered in both in 5.56mm & in .223 rem. So for the gunsmith to tell you that your ACR is not compatible is ridiculous.
Damn, bro, that is some bullshit if I've ever heard it. Please do post your results, or maybe just a face2face range report.
For a hyped-up, $2,200+ rifle, it had damn well better feed what it is chambered for. Period.
I can tell that your super pissed in this video. I don't blame you. If you have more problems with the ACR or Bushmaster, make more videos about it. Gun owners really need to know this stuff, and gun manufacterers need to respect the power of YouTube.
thats bull it should take 5.56 why make it .223 what the hell are they smoking over there. my dpms is chambered to fire .223 i think but it runs 5.56 better then it runs the .223. great vids keep them up
u didnt know it is supposed to fire a .223

@mattpkp I am referring to the smith at Bushmaster. Who do you think fixes the rifle when you send it back for service?

@jdeluisa Wow im disgusted. It is terrible.
For the amount of money these rifles cost it should be " Thee" rifle to own.
i appreciate you recording this and posting for others.
The gun smith needs to pull his head outta his ass.
Do they think you enjoy having to sending your rifle to get it fixed?
Total bullshit you had to put up with.

@mattpkp Thank you! Refer to ShooterReviews it shoots 5.56 (.223)
Blitz0043 1 year ago
@mattpkp Actually, civilian version of Bushmaster ACR uses .223. 223 has lower chamber pressure than 556 - so if there is a higher pressure in the chamber it will suck back the empty shell. This is true for all Bushmaster ACR manufactured by Remington - the hammer that regulates piston has different size of pressure release for 223. Thus, DO CONFIRM WITH THE MANUFACTURER WHETHER YOUR ACR REQUIRES 556 or 223! (Remington wants to sell more 223 bullets :( )

@mattpkp I AGREE 5.56 IS THE SAME AS 223 BUT YOU CAN GET DIFFERENT GRAINS ON THE ROUNDS

1x9 twist hmmmmm...55 gr OR higher. Don't these 1x9's fire a hotter round?
MasterBlasterMusic 1 year ago
@MasterBlasterMusic It's the other way around. Mil Spec barrels are 1:7 twist because this helps to stabalize heavier bullets. The folks over seas have found out the the 55 grain bullet rarely stops somebody on the "first try". No so with the 77 grain Seirra Matchking bullet (Mk 262) which has way more first shot kills. It will not fire accurately from a 1:9 twist barrel. Most civilain AR's sold in the US are 1:9 because is adequate for the 55 gr .223 remington round with is uber avaliable

i thought that .223 and 556 were supposed to be basically the same, with only minor difference? shouldnt they both work in a gun chambered for either? im gona try to research more i ll let you know if i find anything

I love that they told you not to use 556
I thought this rifle was designed for the military? Who use 556... Just kinda funny. Is it working any better lately?

@LotusKnives Did you see the comments of the two pinheads who posted just prior? According to them, niksknicks and blitzoo43, there is no difference between 5.43 NATO and .223 Remington, that I am a retard for believing that there was a difference, and that I am naive for thinking that it made any sort of difference at all in the performance of the rifle.
jdeluisa 1 year ago
@jdeluisa yea they probably know nothing of the higher chamber pressures produced from a 5.56 vs .223, it makes sense that the ACR wouldn't handle it though, since it is a civilian gun, they figure people are shooting 100% civilian rounds

@smartpartzzkidd I agree, the bolt is cycling too quickly and the brass is getting trapped.

@niksknicks I think your comment should stay up so I will repost it. It is interesting to me that you and Blitz post something then take it down so other people cant read it.

@niksknicks I can't believe you're actually this naive. You justify your "differences" between a 5.56 NATO and a .223 Remington with "AR15.com." So I went and took a look at his supposed authority on the ACR and what was it? It's a friggin forum! LOL! I actually started cracking up out loud it was so funny. This just proves my point that you messed up your gun, got hustled, and now want a phantom answer for it. Oh btw, the ACR is the best rifle I've ever shot. When i get a camera, I'll show you.

@niksknicks The source I quoted is directly one of the customer service managers at Bushmaster Inc. in response to these videos. While it might be a forum, there are a lot of knowledgeable people on it. BTW, when you get a camera, why don't you make a video.
jdeluisa 1 year ago
@niksknicks Another thing, when you get near the 5000 round count I hope your ACR continues to function flawlessly.
jdeluisa 1 year ago
Wow dude, You really got hustled...a .556 NATO is the same as a .223! Maybe you should actually listen to Blitz...he sounds like he knows what he's talking about dude. I would laugh at you but I actually feel bad for you.

@niksknicks From Bushmaster as found on ar15.com, "The failure of 5.56 rounds in ACRs is beng looked into very seriously by the engineering dept. at BFI. The problem will be corrected and customers will be taken care of. For the record the subject rifle was test fired 150 rounds without a single malfunction before it was returned to the customer. The problem was it was fired with .223 Remington ammo which works fine and we are having trouble with 5.56 NATO ammo.
jdeluisa 1 year ago
@niksknicks continued, "It was not listed in the paperwork the first time it was returned what kind of ammo was being used. Unfortunately 95% of the time all of the ammo on hand at BFI is .223 and not 5.56mm. This will obviously have to be changed here in the future."

@niksknicks and continued, "Again, on behalf of BFI my apologies for all of the confusion and frusteration. I don't come to AR15.com very often, but I'm hoping at least some of you believe that we really do care. We're dealing with a lot right now. Please be patient with us. Thank you all."

Respond to this video... Blitzoo43 is an idiot. There are several differences between 5.56 and .223. Higher pressures and different leede. There are reasons the military uses 5.56. It's frustrating that there are so many people on youtube who are more than willing to make negative comments when they don't know what the hell they are talking about. It's even worse when they don't have any videos of their own so they are unable to "put their money where their mouth is" so to speak.
jdeluisa 1 year ago
@jdeluisa there is not a big enough difference that would do any sort of damage rifle. just admit ripped off. theres a reason most 5.56 ammo has / .223 on it and most .223 ammo has / 5.56 on it. one measurement is metric and the other is standard. o wait i forgot your retarded.... that means one is millimeter and the other is inches.
Blitz0043 1 year ago
@Blitz0043 Did you read any of the direct comments from the engineers at bushmaster I posted above? There is a difference in the pressures and the chamber leede between the two calipers. There have been damaged receivers. NATO specification allows a higher chamber pressure. NATO EPVAT test barrels made for 5.56 mm NATO measure chamber pressure at the case mouth, as opposed to the location used by the United States civil standards organization SAAMI
jdeluisa 1 year ago
@Blitz0043 The 5.56 mm NATO chambering, known as a NATO or mil-spec chamber, has a longer leade, which is the distance between the mouth of the cartridge and the point at which the rifling engages the bullet. The .223 Remington chambering, known as SAAMI chamber, is allowed to have a shorter leade, and is only required to be proof tested to the lower SAAMI chamber pressure. To address these issues, various proprietary chambers exist, such as the Wylde chamber (Rock River Arms)
jdeluisa 1 year ago
Respond to this video...Using commercial .223 Remington cartridges in a 5.56 mm NATO chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223 Remington chambered gun due to the longer leade.[14] Using 5.56 mm NATO mil-spec cartridges (such as the M855) in a .223 Remington chambered rifle can lead to excessive wear and stress on the rifle and even be unsafe, and SAAMI recommends against the practice.

Respond to this video...Obviously the smith at Bushmaster was full of shit. That was the whole point of the video. And it's obvious that the ACR is not feeding 5.56 well and it's not just my rifle. They did have to replace my gas block, regulator, extractor spring and recoil spring and I'm still waiting for them to send it back. Did you ever consider there might actually be a problem with the design or their quality control?

@Blitz0043 Saw the post you deleted where you state, "lol this is rediculous... i fire 5.56 natos in my ACR and wait.... 5.56 is a .223 DUH! you got played."
DUH? Maybe you should look into this a bit before you make a stupid comment.
jdeluisa 1 year ago
@jdeluisa '
Not a stupid comment considering that the only difference is the amount of brass, and one has a slight more powder. I deleted my comment because I didnt ant you to seem dumber than you already look. I own an ACR and I can even use junk ammo without any worry of jamming. SO whatever you did to you rifle makes you an idiot.
Blitz0043 1 year ago
@Blitz0043 Well, there is a little bit more to it than that - maybe you should look it up and enlighten us all. BTW - I noticed you didn't have any videos of your own to show? It's pretty easy to sit back and direct stupid comments as others when you don't have anything of your own to show. Do you really own an ACR or is it some sort of airsoft knock off/Modern Combat wet dream?

@jdeluisa LMAO at least I wasn't to cheap to upgrade to the enhanced version. 5.56 mm or .223 inch. Don't pose as post military than accuse me of not knowing what I'm talking about. I didn't break my gun, and I'm sure that I've put more rounds down range. Talk to me when you know what your talking about. I'll make a video of me firing my acr enhanced and post it when I'm not at college.

Well what I don't understand is on Bushmaster's website, in the F.A.Q. section, it says all Bushmaster rifles are chambered in both in 5.56mm & in .223 rem. So for the gunsmith to tell you that your ACR is not compatible is ridiculous.
dhours7 1 year ago
Damn, bro, that is some bullshit if I've ever heard it. Please do post your results, or maybe just a face2face range report.
For a hyped-up, $2,200+ rifle, it had damn well better feed what it is chambered for. Period.
I can tell that your super pissed in this video. I don't blame you. If you have more problems with the ACR or Bushmaster, make more videos about it. Gun owners really need to know this stuff, and gun manufacterers need to respect the power of YouTube.

thats bull it should take 5.56 why make it .223 what the hell are they smoking over there. my dpms is chambered to fire .223 i think but it runs 5.56 better then it runs the .223. great vids keep them up
