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?
Hugh87 on Oct 27, 2018
BEST ANSWER: Buddy, size matters and I think your girlfriend is trying to tell you something.
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.
Is the buffer tube mil-spec and can it accept an upgraded buffer system (jp captured buffer system)?
Casey D on Apr 27, 2018
BEST ANSWER: Yes, it’s a standard buffer tube and to add lenght you can add an extended buffer tube.
Can you use this lower receiver for a 16" 5.56 upper or only short barreled rifles?
Tator on Jan 27, 2019
BEST ANSWER: This is a pistol lower so a 16” barrel or a short barrel will be fine with this receiver.
What's the difference between this lower and your classic lower (currently out of stock) that has the same adjustable pistol brace?
Rob R on May 30, 2018

Will a Law Tactical folding stock/brace adapter work on this?
Jamie W on Jun 9, 2018
BEST ANSWER: Yes
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.
What is the weight of this product in ounces?
Derek D on Sep 15, 2018

For a AR lower to be pistol leagal doesn’t the lower need to be stamped with the word Pistol on it?
Brian S on Jun 9, 2019
BEST ANSWER: No. From my research, when to do the 4473 form the ffl will mark it as “other” unless your state has laws saying it has to be marked “rifle” or “pistol”.
Does this lower have word.
" pistol " stamped on it ?
Jerry on Jan 23, 2019
BEST ANSWER: No Jerry it is stamped PA-15 multi. Personally as a hobbiest gun builder, I don't want a lower stamped as pistol nor do I like a lower stamped .223. I m very happy with my PSA purchase. I hope this helps you.
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.
Is this a pistol lower?
dustyDusty on Oct 28, 2018

Bob B on Oct 22, 2018
BEST ANSWER: Yes, a qd sling swivel will connect to either side of the brace just behind the length adjustment release lever.

This is my second sba3 lower from psa, the first one was good, this second one has deep machine marks that I am not really happy about, if I run my finger thru them I can feel the bumps. So I give it 3 stars this time.

Great little lower at a super good price!
I purchased this lower to mate up with a pistol upper (product number, 5165447890) and I am very happy with both. Upper has 10.5 inch barrel with a 7" M-Lok rail. I did a few things to the upper as well as the lower as you can see in the pictures.

Fit and finish on the lower (and Upper) from PSA was better than you would expect. Probably the most amazing thing was the trigger that came with this lower. While it is not up there (and they do not claim it to be) with some of the high dollar triggers it is the best on an entry level AR platform I have felt. It was kind of a shame to remove it but I already had a Fostech Gen II Echo trigger to replace it with. The one big draw back is it comes with a standard buffer. And yes to get the thing to function correctly with the Fostech I did have to go to an H buffer. Besides putting the trigger in, I really didn't have much to do more with the lower. The brace is the very best I have shot with! The magpul grip is very nice also. Did a little detailing for looks and put it all together. Nice shooter and the Flaming Pig break really helps push the sound, concussion and heat away from my hands and face. Even though I did not use it I have to mention the trigger again. PSA put a very nice, for mil spec, trigger in this lower. I certainly would buy again and can recommend this. You may want to go ahead and order another buffer while you are at it.

PSA AR15 Complete MOE EPT SBA3 Lower - 5165448150
Currently using this with a PSA 8.5" 22 upper, and sometimes with a friends 556 10.5" upper. Works great with either upper. I replaced the trigger with a CMC 3.5# trigger which made it even better. It worked great out of the box with the 5.56 and 22. Also shot it with a 10" 300 BO.

Tried a PSA 9mm Gen 4 upper with a Colt type magazine block and it didn't work too well with that, but I'm happy with the 22 upper. Will get either a 5.56 upper or a 223 Wylde upper for it eventually.

Great fit and finish, would recommend to anyone.

5 Stars for Service
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 IT....so 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.
