Home Forums Hunting & Shooting AR and Tactical Rifles 10.5" AR-15 5.56 Pistol

Looks good!

Mine balances at the magazine well. Not sure how the weights compare between the SBA3 and your brace.

The SBA3 weighs 7.2 oz, and I'm using an H3 buffer that weighs 5.3 oz.

7 lbs, 10.7 oz. That's with 28 rounds of M855 in the magazine.

I have a H3 buffer on the way. I was going to shoot it first to see how it goes, then replace it and see what the difference is. Did you shoot yours with the supplied buffer? Overgassed I'm betting?
I'll have to weigh it tonight and see what it comes up at.

I just bought the upper alone, so no included buffer.

I started off with the H3, thinking if it was too much, I'd put a standard buffer in there. But it has ran great with the H3 from the first round. And I've shot factory and a few different handloads.

H2 in mine, but havent gotten around to shooting it

I bought several hundred Fed Gold Medal Match 69gr SMK's to baseline my 223 AR's including the PSA. I have tried this in the past with Black Hills 75 BTHP and was not happy with the results. I used my Lilja barreled Montana that has proven to be 10-shot MOA at 100 to test the GMM and even though these groups are strung vertical the GMM was well under 1".




PSA Un-suppressed




Suppressed





Although this is a 10.5" thread I will post the 16" Faxon Pencil results since I have played hell trying to get any of my AR's shooting decent. I will save the 16" BHW results for an appropriate thread, those groups split the difference between the PSA and Faxon and I am very happy, this seems to indicate my loads are the issue rather than my equipment, assembly or technique.

Faxon Un-suppressed




Suppressed

I realize this is a side note to the point of your post, but maybe helpful info - the two groups shown above represent a pretty typical POI change between suppressed and unsuppressed. The easy way to deal with it is using a mil/mil optic, and noting the POI change on your dope chart. For example, maybe the suppressed group POI is 0.7 mil down and 0.1 mil left. With that info recorded on your dope chart, when shooting suppressed you can simply add 0.7 mil to your drop values at any distance and dial the 0.1 mil right, and you'll be zeroed for the suppressor.

Note that in this example we are not recording POI change in inches, nor do we care. That changes with distance, but the mil offset does not.

That may be already obvious to you, but some guys struggle with it so hopefully that helps.

That Faxon pencil barrel is a shooter too!

Well dang , I went and read this a week or so ago and got one of the $239 uppers. It came in yesterday and soon as I held it I knew I knew it is going to be a fun gun to shoot. My better half said she thinks it's the perfect size for her to shoot. Dang , may have to order another.

Two is one, one is none.....grin

Laighing. Yep.
