How to Zero your AR15 / M4 / M16A2 Platform: Mechanical Zero & the 25m Target

[jimothy183]

Just so you know Steve has now put up an annotation @ the 7 min mark to address the issue you talk about in your vid.

But just to confirm did you say that everything else in his vid is correct?

[semiautoriflelover1]

@jimothy183 yes, I believe everything else he said was right. I just didn't like his attitude problem he had when I made a comment to him, he was attacking me and I was very nice to him and just said he made an error. he came back with all this nonsense about being in Army and they used the large peep, as we know that was wrong.

[hlads66]

Wow dude you are a hateful individual and are hell bent on dissproving this guy! You are so worked up you are breathing hard! WHO CARES!!!!!!!!!! And we all know that military manuals are ALWAYS PERFECT. His video was very good with some errors! SO WHAT!!!!

[semiautoriflelover1]

@hlads66 Who Cares? I care, if your life is on the line then you want to zero the correct way. The guy who made the video is always talking about the end of times and combat shooting so he is talking about guys using their rifle for defense. He is full of shit. switching from small to large peep at 100 yards will change impact 4"

[TabCrusher]

good job,this is gross negligence,i watched this guys video and luckily had my colt manual which contradicted the use of large sights,this guy could get someone killed!

[hahaland74]

Wow dude. STFU and chill out. Holy fuck

[ivebeenrocked]

@hahaland74 why? hes right on with this video. steve needs to correct that shit.

[ThermalSh0ck]

im christian and i have to say,that guy is a false teaching christian, a false firearm teacher he is hateful towards people who take the time to watch his horrible videos, he blocks you if you go off topic a little bit or if you try to point out to him when he's wrong, he should take that video down, he is miss leading people, also the big aperture can be used up to 200 meters with a 25-300 M zero, tat's why its marked 0-2, but not for sighting

[semiautoriflelover1]

@ThermalSh0ck Thanks the comment

[diosdadoapias]

@semiautoriflelover1 the large peep sight is only use when visibility is not good and the shooting distance is w/in 200 meters/yards or lesser. That is the situation provided by the Colt manual w/c u are going to used the large aperture. But when visibility is good and the distance is close or far, use the small aperture which is for normal shooting.

[arsdag81]

that dude must have really got to you or you were just bored as fuck.... of course you use the small aperture everyone who got trained on an AR knows that and does that, there's no arguement.

[RobbieGTV]

I would think you would run a 50m zero with your ARs no? So much flatter. For me with he range I think of the AR carbine to be working in 50/200 is ideal. The original 25/300 I suppose could make sense with 20" rifles though and I do know plenty of guys run that on carbines. Just curious what you run. I like a 25m zero on sub guns though obviously in any caliber, shotguns too. .308 bolt guns and AR10s at 100

[semiautoriflelover1]

@RobbieGTV I always used the 300 meter zero for the first 7 years with the full sized rifles but always hated that the shots were so high at 100. Then one day I found out how you adjust rear sight to give extra clicks and you can still have 300 zero if you wish but then I loved the 50/200 zero, with a M4 you zero at 50 using 55gr or 62 gr and it's almost dead nuts at 200, only 1 click front sight maybe depends on ammo etc. Mine was -1" low at 25, dead on at 50 and 200 and 1.5" high at 100.

[semiautoriflelover1]

@RobbieGTV The US Navy Seals used the 200 meter zero and many of them even like a 100 meter zero because the drop is only 1" at 200, 90% of their shots were head shots at 100 the article I read said. Kyle Defoor, type his name in google and read his stuff about 12 days of the zero.

[black1705f]

We never used the large peep sight except for once at a low light shoot. We never did the count the clicks on windage and divide by 2 thing either. I think they did that on M16A1's. The M16A2's have the graduation marks and we just eyeballed them and made adjustments if needed to windage. And we sure as hell didn't go calling a magazine a clip either.

[semiautoriflelover1]

@black1705f I just placed it dead center with line then shot and remembered how many clicks over it was for zero. The M16s don't have as many clicks and you have to count, the peep on the M16s were different, one for long range that extends zero to 375 yards and has an L on it. With other peep the zero is -1 low at 25, dead on at 42 meters and dead on at 250 meters which is -7 low at 300 meters.

[danthman114]

it is true, you dont zero with the big aperature... but the windage is seldomly in the dead center after zero. i dont really look at those marks. i remember how many clicks left or right my true zero is.

[semiautoriflelover1]

@danthman114 when i made this video last year i had 20 guys say they zeroed with large peep because of the other unclear video.

[modex20]

Do you zero at the z position with m4 rifles or just m16?

[semiautoriflelover1]

@modex20 With the shorter barreled ARs you have to place it on the Z if you want the standard 300 meter zero. With the M4s I never use a 300 meter zero, I zero at 200, I have a video with this.

[jetfuel545]

Did he ever correct himself on that. I have never seen anyone zero an AR with the large aperture. It just does not make sense in the first place. I can not believe he does not know better

[semiautoriflelover1]

@jetfuel545 He claims he learned to zero with large peep Army. He never had an M16A2 in Army most likely M16A1.

[danthman114]

@semiautoriflelover1 the person i think youre talking about didnt zero on the large one. he zeroed on the small @ 300 and said the large was for up to 200, hence 0-2.

btw that guys rifle in the video; the large aperature looks to be drilled off center to the right...

[semiautoriflelover1]

@danthman114 No he said to keep the large peep up and use that all the time, check the comment section from a while ago. Marine manual and Colt manual say to use the small peep for most shooting including zeroing. Steve says he uses the large peep for all shooting. I didn't know we are in a combat role here in the states, for me and jetfuel we use the smaller peep so we can be more accurate. For low light combat shooting you can just keep both eyes open and use the small peep.

[semiautoriflelover1]

@danthman114 You know that the peeps are off set right? If you zero with one peep then switch to other the shots will be impacted 2-4" different depending on the brand of sights you have, my colt I zeroed the correct way with small peep for 300 meter battle zero back in 1995 then flipped to large peep and shots impacted 4" off from where the shots with the small peep went. This is why the military is using scopes now because everyone gets confused with all this stuff because they can't read.

[redmule02]

@semiautoriflelover1 no armarlite was the first to produce the ar series then they sold the rights to colt. but they use acogs and e o techs and serveral different scopes for faster target acquisitions and higher hit probabilities than with opens sights but you are right you dont use the large sight unless you where a gas mask or low light/night time shooting im not arguing just saying you are right about the sights later

[semiautoriflelover1]

@redmule02 that is wrong sorry, ARmalite never produced a rifle, they made prototypes then were in debt so they sold the rights to colt, Colt made the very first M16s and civilian AR15s, this info is not hard to find, zero Armalite rifles were sold to the public until 1996 when a former Army officer bought the name ARmalite and started making rifles, that new company is not the original company.

[redmule02]

@semiautoriflelover1 never said armarlite sold anything to the public, second you have to produce a product in order to have a prototype. im not arguing with you friend were saying the same thing.

[semiautoriflelover1]

@redmule02 You better buy a book about the AR15 rifle it will tell you all you need to know. Armalite doesn't own the rights to the AR15 name, the current Armalite company has nothing to do with the original company, Stoner also consulted for Colt. The M16 that was used in Vietnam war were Colts, then they had a few GM and H and R but never an Armalite factory produced AR15 or M16. The civilian AR15 was all Colt from the 60- until the patent rights were up, now you have a million companies make

Class is now in session!

[semiautoriflelover1]

@XvChriisvX Yes, I had to set the record straight.

What I meant to say was that he is a guy who pretends to be a good Christian but doesn't act like that.
