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.

Apoy G on Apr 25, 2018

Rob R on May 30, 2018
Will a Law Tactical folding stock/brace adapter work on this?
Jamie W on Jun 9, 2018
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.
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.

would this work with an AR pistol 7.62x39 upper?
HeavyHands on Jun 11, 2018
BEST ANSWER: Yes. You can buy 7.62 p-mags. I put a CMMG mutant upper on mine. Just follow your state regulations on barrel and overall length requirements.
What do I need extra to make a complete working gun ?
Robert B on Jun 24, 2018
BEST ANSWER: Pick whatever length complete upper you want. This is a pistol lower. So you need upper, bcg, charging handle, some sort of sights/scope/red dot/ aiming device, and mags. Might want ammo at some point.
what else will i need to finish the lower?
richard S on Jun 30, 2018
BEST ANSWER: Nothing. It is already complete. Just add a complete upper and your good to go.

Will this work with 300 blackout upper?
R C on Jul 1, 2018
BEST ANSWER: Yes absolutely. I purchased the exact lower along with a .300 BLK. pistol length upper. The combination functions flawlessly. Go for it, you'll love it.
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.

Steph on Aug 24, 2018

Does this lower have the last round bolt hold open feature?
PaulO on Aug 29, 2018
BEST ANSWER: I did not know that was a feature. The bolt will lock back after firing the last round.
Will this mount to an m4 upper , if so any brand or psa only?
COLDBLOODED on Jun 12, 2018
BEST ANSWER: It will work with any M4 AR15 upper. I personally have had great experience with Palmetto State so I would definitely suggest their uppers, but it is universal.
Is this a Low shelf or High shelf lower?
Robert H on Dec 10, 2018
BEST ANSWER: Palmetto makes fine products in my opinion, I have been very pleased with the many items purchased from PSA. With that said I think its high end but i'm also not a person swayed by "Name Brand" but by performance. I have never had an issue with PSA products and I believe you will be pleased.
What is the LOP when shouldered ?
Doug L on Dec 2, 2018
BEST ANSWER: It will adjust anywhere from approx 9 1/2 inches to 12 inches fully extended.
The adjustment is easy and you can adjust it to anywhere in between just let off
the little adjustment handle and it holds in place just fine! I'm very happy with this set-up!
Is this compatible with the PSA 6.5 grendel upper?
Jeff M on Jul 31, 2018

Nick m on Jan 16, 2019
BEST ANSWER: And no, no receiver tighten down. This is a forged mil spec receiver, not milled custom receiver

Awesome price, arrived damaged
I ordered this lower to match with a 10.5” upper. It arrived and looked good until I attempted to extend the brace, the pistol grip loosened and almost fell completely off. After removing the pistol grip cover I found the Allen head screw appeared to not have been tightened. I attempted to tighten it and found the threads to be terribly boogered. After tapping the threads and re-installing the pistol grip all is well. The lower performed as expected and the enhanced trigger is clean breaking with a short tactile reset. I would have given 5 stars but arriving in the condition it did brought it down to 3.

Response from Palmetto State Armory
We do apologize for that. Please contact Customer Service so we may resolve this issue.

I’m a police officer, in my opinion, this is the best priced pistol lower (with the SBA3 brace) available. I have been ordering parts from PSA for years now. I took my completed pistol (this lower and the 8.5 inch complete upper) to work. Five of my co-workers have decided to order this lower with the 8.5 inch complete upper.

Good Brace For Cost
Amazing Fit & Finish Functioned flawlessly with a binary trigger! Great Deal Will Purchase Again
December 25, 2018
Would buy again
Very good lower, matched up tightly to a psa 10.5 upper. Only problem I had was that the buffer spring retainer detent fell, I had to twist the tube one more revolution to keep it from coming out again, trigger feels similar to my alg trigger in my other ar15. Would buy again.

Nice lower
Fit and finish are very good, the trigger is smooth and crisp. I am very pleased with the quality and for the price you cannot beat it. Shipping was fast, I ordered on Tue night and picked it up at my FFL on Fri.
PSA is really doing a fantastic job of making and selling high quality, affordable AR parts.

I cannot comment on their customer service because I have never needed to contact them. I have bought stripped and assembled lowers and a couple of assembled uppers. No complaints so far.
