Anyone running a 12.5 upper? - Tipsymutt - 06-21-2020

Hi guys. Are any of you running a 12.5" barreled upper? If so, what are you running? How his your reliability been with it? Do they prefer heavy or light bullets? Never had a short barreled AR, so just looking for some guidance. Want to pick one up before November in case things go sideways.

As always, thanks!

I’ve had 3, all worked well. Had a PSA stainless 12.5 upper. A Monster group buy 12.5 upper that I put together and my current Lilja 12.5 upper I put together. All very reliable from what I used them, the PSA and the monster barrel shot damn near identical. They preferred the federal AE 90gr TNT factory load the best for a factory loading and hand loads liked the 129gr ABLR or the 120gr ELD-M.
The Lilja seems to like about anything so far.

You should get one, you will enjoy it.

I have a 12.5 and 12 inch that I put toghter.

12.5 is a custom barrel from PF.

12 inch is a sixfivearms barrels sold here on this fourm.

Both shoot whatever I put in them and both produce sub moa groups with their handloads.

I had load 120 gold dot, 129 ablr, 123 eld-m and 123 nosler cc, 85 trex by maker.

Both have been totally reliable.

Have taken both to 600 yards on steel target and both will kill any deer are hog I want to kill inside of 250 yards.

I have a 12or 12.5” pistol barrel made by Faxon. It is one of the first 12” group by barrels sold on this forum.

I run 100gr nosler bt over 8208. I really think it would do sub moa if it had a suitable stock and optic. With the brace and leupold hog plex reticle I get moa out of it. It’s primarily my climbing stand gun.

I’ve got a Nitride PSA 12” pistol kit and just finished a group buy Green Mountain 12” 1:7.5 twist Monster logo barrel. Both have functioned 100%. Looks like the Monster barrel is going to be more accurate than the PSA but I haven’t had time to shoot Monster barrel past 50 yards.

Waiting for the rest of my parts (thanks panic buying) to complete my 12.5" BA build. Hope to get a 12" sixfive monster barrel, too... when they get back in stock.
