AR10 / Large Frame ARs - Accuracy
- Thread starter LVLAaron
- Start date
Depends on what AR10...And if the shooter knows how to drive a large frame semi. If your shooting something high quality or a custom with a Bartlein, Kreiger, JP barrel then 0.5-0.75moa
And Jusy FYI OP, theres a metric shit ton of info on this same suject, Google's your friend.
With my Criterion barreled, lapped receiver face and Loctited ( 609 ) 18" Middie and FGMM 168gr benched, scoped, etc...
I can routinely shoot like this with the 168gr FGMM ... I am not bragging... but the rifle is capable of some fine accuracy.
I have done this enough times to have full confidence in the 168gr FGMM.
I doesn't shoot everything like this... but.. it loves the FGMM
Some day when I have the time to develop loads... I hope to do better.

Yes... and with the factory SS barrel and the Nitrated barrel.
I will IM you some links including the 6.5CM Uppers results.
That's certainly interesting. I was having a lot of trouble with a gun. Ie, testing HUGE amounts of precision handloads in my first AR10 and all of the groups were 2.5 inches. No variation. I have a fresh set of shims... and I have loctite. Can't hurt to try. It's already been lapped.
Loctiting the barrel to the upper receiver has positive results in terms of accuracy on the large frame guns. Bfoosh and I both bought PSA Gen2 rifles when they were on sale last year, he’s gone farther down the rabbit hole than I have so far. I’ll spend some money with SLR to get an adjustable gas block and a free float hand guard to give the OEM PSA .308 barrel a chance before I put another tube on it.

I have a GA Precision GAP-10. It will very consistently group 5 shots into .5-.7 moa. I have multiple pics of .5 groups.
The barrel is the heart and soul, the engine if you will, but the shooter is the bigger variable. Just because a Porsche can go 180 mph, doesn’t mean every driver can take advantage of that performance.
There are more moving parts to a gasser. Tiny mistakes that a bolt gun will forgive, a semi-auto will not. Position and follow through are very important with gassers.
There are truly AR-10’s that can shoot neck and neck with bolt guns, if the shooter knows how to drive it.

This post gives me a little hope, I’m bringing an Ar-10 rifle home this week. I will have to read up on some of the do’s and dont’s of the AR-10 world...
Read up on follow through. It is critically important when shooting a gas gun
Lowlight and some other guys have posted instructional videos on youtube.
Whenever I put together an AR I like to see 5 rounds into an inch at 100 using decent ammo with a point of impact that doesn't wander around the target. If you are getting that then fine, if not then something is going wrong somewhere.
The Youtube channel is called SHLowlight there's a ton of videos in there.
