How far does the stock adjust to all the way out ??
Edwin A on Jun 1, 2018
BEST ANSWER: Measuring from the aft face of the receiver extension castle nut, there is approx. 2 3/4” of adjustment from fully locked closed to fully locked extended. Or closed length 6 1/4” too about 9” extended. A very easy to use compact brace.
If I removed the flash can, what would the overall length be when added to a PSA AR15 Complete MOE EPT SBA3 Lower with the brace fully extended? I'm trying to figure out if the length would be greater than 26 inches so I could include a vertical-fore grip.

PSA 10.5
PSA 10.5" 5.56 Lightweight M-lok Slant 12" Upper With MBUS Sight Set, BCG, CH, & Fluted Flash Can - 516447012
BEST ANSWER: Overall length does not include muzzle device, you measure from the threading of the barrel to the end of the receiver extension for overall length. Unless you pin and weld a muzzle device, then by law it becomes a part of the barrel.
My girlfriend told me that if I pair this with a 16” upper, I legally have to register this as a long barreled pistol. Is this true?

BEST ANSWER: Buddy, size matters and I think your girlfriend is trying to tell you something.

Can you use this lower receiver for a 16" 5.56 upper or only short barreled rifles?
Tator on Jan 27, 2019
What exactly do I have to do to this lower to allow for it to take Glock mags and use is as a dedicated 9mm pistol? Obviously I would need to purchase a 9mm upper for it.
Alexander B on Jun 12, 2018
BEST ANSWER: Stern, ATI, ProMag, and TorkMag all make glock mag adapter blocks that will fit any standard ar-15 lower. If you plan on it always being a dedicated 9mm I would go with tha PSA ar9 lower. I have one and it works perfectly. Just doesn't have the LRBHO.

would this work with an AR pistol 7.62x39 upper?
HeavyHands on Jun 11, 2018

What do I need extra to make a complete working gun ?
Robert B on Jun 24, 2018

Can this be used with 300 black out up???
Dar on Sep 24, 2018
BEST ANSWER: yep! i paired it with psa 8.5” .300 upper with keymod handguard, swapped the moe grip to moe k2+, and put an ergo brand handstop and ergo rubber keymod grip panels on. i also stuck and indian creek removable blast shield on the end. it allows you to remove it and have benefits of flash hider when outdoors, but provides much needed forward-blast diversion indoors/close quarters. paired with the optic/sights of your choice it makes a quick and sure handling pdw.

I just got this on 4/15/19. The safe only goes on after it's cocked. It doesn't go into safe after It fires. Am i missing something or is this the way it's made?
Capone_50 on Apr 16, 2019
BEST ANSWER: Yes, that is the way the weapon is designed. This alerts the shooter that the weapon has been charged and may have a live round in the chamber.
Is this lower compatible with other brand uppers and if so, which brands?
Gaige on Mar 2, 2019

But I would recommend using a pametto State stripped upper and use which ever barrel you like only because Palmetto states take down pin holes have a tight tolerance compared to other manufacturers

The lower came in with a loose buffer tube and a sloppy safety assembly. I don't know what they did for sure but it looks like they replaced the castle nut and I am guessing they replaced the detent pin for the safety because I found a random pin (looked like a take down detent pin) in the box. I'm guessing the wrong pin was installed initially. Got it there and back in a week...good job guys! Only suggestion is to put a copy of your work order in the box when you send repaired items back. Thanks PSA

LOVE IT SO MUCH...GOT 2...see review
I got this a while back. I ABSOLUTELY LOVE much so I got two. My friends liked it so much, they got one. I have a YouTube channel and wanted to start doing "Pistol Upper" reviews so I need a economical lower to get going. WOW, can't say enough but don't take my word, check out ALL the videos with MULTIPLE uppers and see for yourself. YOU WILL NOT BE DISAPPOINTED....I HAVE NOT BEEN.

Not a Magpul Trigger Guard
Picked my lower up from my FFL this evening, and noticed the trigger guard is not the Magpul trigger guard, as was advertised as being on this lower. Instead, mine has a flat milspec aluminum trigger guard. Not happy. Now I have to wait and see if PSA sends me the correct Magpul trigger guard kit (trigger guard, pin, and screw), and then I have to remove the wrong trigger guard, and install the correct Magpul trigger guard. Not sure how this slipped thru QC.

Best brace I have ever had
Love this brace. Good crisp trigger easily adjustable brace fits Avery solely on all my uppers. What a great bargain. The strap is to short, and I called Sig brace and they sent Mr out another longer one for free.

Great value, good tolerances.
I'm very happy with my purchase. Packaging and shipping are great. PSA orders have always been fast and trouble free for me. Finish is nice, trigger is really nice and I won't likely upgrade it (way better than a mil spec trigger), and with the adjustable brace you can't beat the price. I paired this with a 10.5 PSA .300 upper. The tolerance between the PSA upper and lower is OK. Loose enough to break down by hand but not too much movement. For the price, great. Not a zero movement/rattle free fit, but then gain, I'm all in under$500 for the whole thing. Very pleased!

AR15 Pistol...Loving it.
Awesome build. Spent about 8 months looking for looking AR15 Pistol. Looked at some nice builds at some local stores but wasnt happy with the completed offerings. A friend recommened PSA for getting what I want out of a build and hands down he was correct. You must be patient and keep looking at daily deals. I finally got the build I wanted. PSA Premium BCG. 10.5" Upper and SBA3 Brace on the lower. Can't wait to hit the range. Well worth the wait on parts coming in.

Me, my brother and nephew all have one. Got it quickly. Overall good, upper/lower fit could be tighter, trigger good for the purpose. Great value.
