What is the weight?
John W on Jul 16, 2018
Weighed myself on my bathroom scale with and without the lower, and that was the difference.
Can I match it up with a rifle upper?
Katheleen G on Jul 29, 2019
BEST ANSWER: It's my understanding that since the Receiver is transferred as a Pistol, a Rifle length upper can be installed, making it a long barreled pistol, and the owner can switch between Pistol and Rifle length as much as they choose. However, a Receiver transferred as a Rifle would meet the definition of a Short Barreled Rifle with a Pistol lower, even if a brace was installed, simply because it was originally transferred as a Rifle. So it is always better to first Transfer/Possess a Receiver as either a Receiver or as a Pistol if you plan on making any length modifications where you aren't certain of the legality.
Is this lower compatible with uppers chambered in 5.56?
John T on Apr 24, 2018
BEST ANSWER: Yes. Specifically pistol uppers chambered in .223 or 5.56 that conform to the AR-15 spec.
Will this work with a 300 blackout caliber upper?
Jim K on Dec 12, 2018
BEST ANSWER: I have a 5.5 in 300 BLK on mine. Works well. Get an H2 buffer for it if it's pistol length though. Good shooting!
Does this include the buffer and spring?
Kaleb S on Nov 2, 2018
BEST ANSWER: Yes, it is an awesome lower. I wish these where out when I ordered my first AR. This is the only way to go for an AR. The only thing I replaced was the safety switch for an LWRC am I safety.
Why does this lower not require an FFL?
Trent S on Nov 7, 2019
BEST ANSWER: This lower does require an FFL.
Do I need some kind of adapter to use it for 9mm rd?
Armando P on Sep 2, 2019

If you wanted this to be 9mm, you would need an adapter. We do not sell them. We do sell 9mm dedicated lowers which take Glock mags that do not need an adapter. Here is a link to our 9mm dedicated lowers.

PSA Customer Service
How do you get this lower to shoot glock mags?
RJ N on Jul 23, 2019
BEST ANSWER: Will this work with a 6.5 Grendel upper?
Looking at a BCA 6.5 Creedmoor upper, would this be a compatible lower?
Daniel H on Aug 7, 2019
BEST ANSWER: no you need a lower chambered in 6.5 creedmore,, this lower is chambered in 5.56 !
Low shelf or high shelf?
Johnny Five on Dec 12, 2018
BEST ANSWER: I’m out of state right now and don’t have it on me, but I’m pretty sure it’s low shelf. The only thing I changed was the safety selector and I remember it being low shelf.
How with this mate to gen 2 upper? If so will there be any noticeable differences?
Wesley B on Jul 22, 2019
Is this compatible with the “PSA 10.5" Carbine-Length 5.56 NATO 1/7 Phosphate Lightweight M-lok Slant 12" Upper - With BCG & CH” upper?
Alexander H on Dec 14, 2018
The fact that the stock is adjustable doesn't made it illegal to use anything shorter than 16" ?

Good pistol lower with the sba3
This is a pretty dam good lower and the brace works nice when shouldering it(hope atf doesnt ban it). I will say this using the brace around my arm scratches up my arm and im a skinny guy. Overall it is what it is and does what its meant to do bottom line!!!

Overall Very Good
Nice lower overall. Trigger is ok, but a polished would be better at this price. Spend a few more dollars for the EPT and Magpul trim

Great product for the price
For the price of this lower you can’t go wrong. Fit and finish are ok for what your paying for it. Don’t expect it to match at DD or others in the mid price range. It does what it’s supposed to and great for beginners or someone that wants a gun they can beat on and not worry about it.

Excellent lower receiver!
I really like this lower and the palmetto state armory upper in 223 wylde was icing on the cake.

Well put together
Fine finish, much better than expected trigger. A little unhappy with finger "grip" moulding doesn't quite fit my hand correctly.

PSA AR15 Classical with SB tactical brace
Everything looks well made. I like look and adjustability as soon as I got it. Looks better than the Shockwave brace, which I have two. PSA is awesome! Fast shipping! I've purchased multiple things from them.

Ok, not great.
Trigger needed work and lower needed anti-walk pins. Besides that, functional lower so far.
