Building an Upper Receiver Part 2

[darmog]

Great vid, but have a question though. Have you heard or found a way to do a build without using a vise? Reason I ask because I live in an HOA controlled condo so no access to a garage for a workbench and there's really nothing indoors to install a vise on without scratching or breaking things. Was thinking about a portable/folding workbench but not sure if it'll hold up when torqueing stuff down.

[uhhhhNick]

How was the finish on you gas block? I got the clamp on version of the vltor and the black phosphate coating just rubbed off on some spots, so now I have a black gas block with steel color showing through, it kinda looks like crap now lol

[dantheman7624]

good video. you need a tri pod for your camera. i got sick trying to watch this vid. motion sickness. i am learning alot though.

[guyverdx94]

@dantheman7624 or one of them POV cameras.

[JulioCHernandez]

How hard is it lining up the gas hole on the barrel with the gas block? I've always wondered this. lol

[R0GUEKN1GHT]

@JulioCHernandez not really difficult at all.

[PotatoGunsRule]

Wow.....so easy! I want to do my own now.

[R0GUEKN1GHT]

@PotatoGunsRule that' why I made the vid, it really is easy once you do it.

[ManFlaver]

awesome vid man. any thoughts on the Vltor Vis? i dont know if im going to go with the VIS or the Mur for my build thanks man

[R0GUEKN1GHT]

@ManFlaver personally I love the MUR but not the VIS. The VIS rails are very large and bulky, and extra heavy compared to a one piece rail. But they are great quality, so it depends on what you need.

[taurus38splul]

Don't forget to do a head space test !!

[R0GUEKN1GHT]

@taurus38splul not if you get the barrel extension already installed on your barrel from a reputable manufacturer.

[turneynicholas]

u forgot the oring on the gas tube didnt u

[R0GUEKN1GHT]

@turneynicholas there is no Oring for the gas tube. this is an AR, not airsoft.

[DaRkiCarbOnz]

did u have to put the bolt together or did you buy one that was already put together?

[EDF6399]

Would a 10 inch dd hand guard cover it up?

[R0GUEKN1GHT]

@EDF6399 yes, barely, there is a small amount showing with a 10in rail.

[EDF6399]

Neverrmind, I saw it, lol, thnks

[EDF6399]

Is your hand guard covering the lp gas block? I can't tell in the video. Thnks

[0122358]

i was wondering...could i use he standard A2 frontsight base/post with this free-float rail system?

[R0GUEKN1GHT]

@0122358 yes you could. the rail should be 9in for a middy, and 7in for a carbine gas.

[flatjawspud]

What about headspace? does it need to be checked? is headspace an issue with AR's?

[Mickeymorris626]

@flatjawspud No, you can headspace an AR, but its not needed. If you want to, it should headspace between 1.4646" to 1.4706" but again, its only needed if your having problems

R0GUEKN1GHT Great video!

[R0GUEKN1GHT]

@Mickeymorris626 thanks!

[R0GUEKN1GHT]

@flatjawspud not if you buy a barrel with the barrel extension installed by a reputable manufacturer.

[pootinhammer]

what are the main effects of the gas block position on the barrel? can you pretty much just put it wherever you want?

[R0GUEKN1GHT]

@pootinhammer there are three different setups for the gas system on the AR: carbine, midlength, and rifle. Carbine is the shortest at around 7in, midlength a little longer at about 9in, and rifle is the longest at ?in. Short barreled rifles will have a carbine gas system, most of your 16in barrels will have midlength (or carbine too), and your 18in barrels and longer will have a rifle length gas system. The longer the gas system, the softer shooting the AR is theoretically.

[pootinhammer]

@R0GUEKN1GHT thanks :-) im always trying to learn a little bit more every day

[bxfi420]

vltor's are so damn sexy! awesome build

[kyle1058]

tape both sides of your pliers, tip i learned from a machinist friend. I'd also recommend putting some blue (NOT RED) loctite on all threaded screws, to keep them them from backing out. Great video, may i ask about how to check or if i need to worry about head-spacing when building an upper?

[yokhomano]

thats a nice build good work

[R0GUEKN1GHT]

@yokhomano thanx, it was a fun build.

[IrishGunNut1996]

How much was this build in all? and can you tell me where you got these parts? and how much they cost?

[TheMisfit621]

Is that a Noveske barrel?

[R0GUEKN1GHT]

@TheMisfit621 it's a white oak armament barrel, I covered all the parts in the first vid if you want more info. the noveske barrels are slightly heavier profile I believe.

[TheMisfit621]

@R0GUEKN1GHT Oh OK, I didn't see the first video. I'm currently in the process of building a high end AR myself and I'm stuck between the Daniel Defense hammer-forged barrel and the Noveske Recon Barrel. Any advice?

[R0GUEKN1GHT]

@TheMisfit621 depends on the mission of the rifle. the noveske barrel is SS, with a heavier profile, and will be more accurate. the DD barrel is HF, lighter profile, and will withstand harder use. so get the DD if you want to run and gun and get a high round count, or get the noveske if you don't mind the extra weight and want to have a tack driver.

[TheMisfit621]

@R0GUEKN1GHT I could tolerate the heavier barrel but at the same time do I really want to? The rifle would be mainly used for run 'n gun but at the same time I have a incredible urge for that accuracy... (I shoot Highpower Rifle matches so its kind of drilled into me)

Also, is the DD M4 rail worth it? I was thinking either the DD 12.0 FSP or the RIS II M4. Know anything about those?

[R0GUEKN1GHT]

@TheMisfit621 the M4 rail is one of DD's older rails, but still excellent. I am currently running one of their lite rails on my most recent build though, and it's awesome. the FSP rail or the RIS will both do you good as well, I do not have personal experience with these, but have heard great things. you can't really lose any way you go with daniel defense.

[TheMisfit621]

@R0GUEKN1GHT The only issue I had with the RIS model is that it is a 2 piece rail. I'm not too sure how well it'll hold up to being thrown around...

[123chubz321]

Sweet setup! How much did it cost?

[Casper48022]

I never saw you put a ejection port dust cover on this.. :P

[R0GUEKN1GHT]

@Casper48022

the VLTOR MUR receiver comes with a preinstalled dust cover and forward assist.

[mythreebuckeyes]

nice video, are you happy with your VLTOR mur upper?

[R0GUEKN1GHT]

@mythreebuckeyes

it's a very nice receiver if that is what you want. I eventually sold it and bought a standard forged receiver and used the extra money on other parts. you also save about 1.5oz. in weight by going with a standard forged receiver. but if you have the money, and you want it for a precision rifle that you don't care about a little extra weight, it's the best receiver out there.

[errorswe2]

Hello do i need a licens to buy a new upper reciver or is it just walk in to a store and buy it ??

[R0GUEKN1GHT]

@errorswe2

no, you don't need any form of licensing to build an upper receiver. you do have to buy a lower receiver from someone with a Federal Firearms license though, and you need the lower and upper to have a functional rifle.

[gunrobot]

awesome vid. thanks for sharing.

[9977jpp]

Have you thought of putting an Adams Arms piston conversion on an AR? Seems like a cool set up. Great vid!

[R0GUEKN1GHT]

not really, never had a problem with DI. also pistons are heavier and have greater felt recoil.
