Is it possible to get this kit in Dark Earth color?
Shane C on Aug 3, 2018
BEST ANSWER: Yes, maybe not here.
I just received my kit. What is logo do you have on the end on the of your brace? I own several of these braces and legitimate ones have the SB Tactical logo. The logo on the one I got is the PSA logo and quality on this brace and buffer tube is nowhere close to the quality of the real one.

PSA SBA3 MOE EPT Pistol Lower Build Kit, Black - 5165448657
PSA SBA3 MOE EPT Pistol Lower Build Kit, Black - 5165448657
BEST ANSWER: I contacted SB Tactical with this questions. Here is the response I received from SB Tactical "We do in fact make the SBA3 for Palmetto State Armory. We partner with many different manufacturers and offer to have their logo on the product versus ours, but these are still genuine SB Tactical products. We ship the SBA3 fully assembled to Palmetto, so we do all the assembly."
Is the buffer tube in this kit 7075?
P V on Aug 18, 2018
BEST ANSWER: I believe it’s SB Tacticals buffer tube which is 7075 on there website
Does all of this work on an AR9?
Eugene on Aug 3, 2018
BEST ANSWER: You will need a 9mm Lower Receiver, Buffer, and spring and you can complete it with the parts in this kit and have a lot of left over parts for your next build.
To make a complete lower all I would need is a receiver?correct
Joel M on Jul 27, 2018
Will this buffer and spring work with a 300 blkout?
Captww on Aug 25, 2018
BEST ANSWER: That has a LOT to do with your application (supersonic/subsonic ammo, barrel length/gas system length, and whether or not it’s suppressed.) that being said, it should generally work.
Will this buffer and spring work for a 7.62x39 AR build?
John G on Aug 13, 2018
BEST ANSWER: Should work fine since you will likely be running a carbine length gas system upper on this lower.
What is the weight of the buffer? Will it handle 5.56 out of a 10.5 inch barrel?
Eugene on Aug 10, 2018
BEST ANSWER: Yes it will. Have used one 10 1/2 in 556 upper to this lower. Love the brace.
Does this work for a 300 AAC pistol build?
Gerry on Oct 26, 2018
BEST ANSWER: I don't see any reason it wouldn't. The only things that are usually changed when building an AR pistol are the buffer Spring and buffer, usually to accommodate pistol rounds. Since the 300 AAC is basically a rifle round (7.62×35mm) you should be able to use everything with no substitutions as this comes with a standard Carbine buffer Spring and buffer.
The picture looks like the FCG is the EPT, but no mention of it within the description. Am I correct in assuming that it does not include the EPT?
Benjamin L on Sep 28, 2018
BEST ANSWER: Just assume that it is standard, and hope for the best! I received one black trigger, one silver trigger in the last 2 bundles I bought. The fit and finish on these lower kits is one of the best I have gotten from the last 5 different vendors. The trigger I received with the last one does look the same as the one I ordered in FDE with advertised EPT. Hope this helps knock you off the fence with or without it is still a great deal
If I put this on an AR9 build.. is it recommended to change the buffer and to what?
V L on Sep 3, 2018
BEST ANSWER: An AR-9 Heavy Buffer and AR-10 308 buffer spring work great for me to limit bolt travel and lessen felt recoil in my PSA 9mm lower.
If I were to use this for a 9mm build.. is it recommended to replace the buffer to a harder one? AR15 buffers don't work well on 9mm, is that right?
V L on Aug 31, 2018
BEST ANSWER: Your best bet is an AR-9 Heavy Buffer and AR-10 308 spring IMHO.
What is the weight of the buffer?
D B on Aug 12, 2018
BEST ANSWER: 3oz carbine buffer
does everything but the buffer spring and and buffer work for the pa10?
Phillip H on Jul 26, 2018
BEST ANSWER: If you're talking about the LPK stuff, no. But the FCG will and the brace and grip work just fine on PA10.
Does this come with a firing pin or do I have to buy one separate?

BEST ANSWER: The firing pin is in a bcg which is not included in any lpk.
Is this kit available with the polished trigger ?
Joe H on Dec 28, 2018
Does the pistol brace have the PSE logo ?
Greg M on Dec 5, 2018
BEST ANSWER: The first one I ordered didn’t have it. But the second one I ordered did. So it may be a toss up.
Should there be a lock washer included in this kit for the pistol grip screw? There was not one in my kit
Diron B on Nov 4, 2018
So I have just got this parts kit been putting it together and I have an extra spring and detent. I'm not supposed to?
Zac P on Dec 5, 2018
BEST ANSWER: Yes, they include an extra of each, for the pivot pin... they are easy to lose.
Just assembled my lower, and I have an extra dent and spring? Is this normal ?
Smitty on Oct 24, 2018
BEST ANSWER: Yes. Those springs are easy to lose, so some manufacturers send a extra or two.
Does anyone know the distance from center of trigger to end of brace fully extended with the Law Tactical installed?
MrMatt on Jan 14, 2019
BEST ANSWER: I have 12-5/8” fully extended. I have a Spike’s Tactical lower with the Fostch echo trigger installed, just to cover all the bases. Love the brace! I’m 6’4” tall and it’s very comfortable to shoot.
I want to use this with a 9mm upper, ar-15 lower and a conversion block what else will I need for this to run reliably?
Moose on Jan 11, 2019
BEST ANSWER: I have this on a dedicated 9mm lower. The only thing that will need to be changed, as far as the lower components goes, is the buffer. It needs to be heavier than what is in this kit. I run a buffer that is arounf 5.5 ounces. I believe this one is around 3ish ounces.
I'm putting this on my PSA AR9 build. Any one know if there are any issues with the tube/spring for the 9mm? seeing some YT videos saying 9mm's require tweaking/upgrading either spring or tube.
V L on Nov 17, 2018
BEST ANSWER: the buffer with this kit should not be used for 9mm probably not the spring either . i used an h3 buffer and a spring from a 308 carbine buffer tube set originally and i put a thick rubber grommet in the buffer tube as a spacer . on a 9mm you want the bolt to only recoil far enough to go past the bolt stop .if the bolt has a far enough run in it will possibly break the bolt stop . i have a LRBHO lower . i graduated to an armaspec srs assembly after about a month or so and it is very nice in that configuration also . i removed the weight in the back of the BCG to allow function as it has a tod in the captive spring assembly . i never experienced any malfunction with either buffer setup on this pistol . i am using both ETS mags and KCI mags and 115gn fmj .
If i wanted to use this on an AR9 build which buffer spring and buffer would work?
John G. on Oct 20, 2018
BEST ANSWER: I think you would need to use the buffer spring and buffer for a 9mm carbine.
Will this work for a .308 build?
Dylan C on Sep 14, 2018
BEST ANSWER: Buffer, buffer spring,both take down pins,and bolt catch will NOT work on .308 build.
Will this kit work for 9mm AR lowers as well as function with the PSA 9mms complete uppers?
Don12 on Aug 16, 2018
BEST ANSWER: Yes it will work with 9mm lowers and psa uppers but you'll need a 7.5oz 9mm buffer.
Will the strap stock fit over a factory buffer tube or does it have to use the tube that comes in the kit?
Harris H on Nov 22, 2018
BEST ANSWER: This brace will fit any standard mil-spec multi-position carbine buffer tube.
Will a Franklin BFS III binary trigger system function in this setup (for example, with a 7.5" barrel pistol length gas system Upper)?
Jim S on Oct 23, 2018
BEST ANSWER: The BFS III Trigger will most likely work. I see no reason why it would not, but if you need further insurance call Franklin Armory. Franklin Armory's website states "Works in most AR platforms and calibers including 5.56 NATO, 308 Win, 300 BLK, 9mm, Rimfire, etc"
Will this fit a AR10 also ?
Victor B on Sep 5, 2018
BEST ANSWER: no, but the brace
Could you attach a rifle stock to the buffer tube? It seems like it's to easy to get into trouble with this type of tube

Great deal
Great brace, nice grip and the lpk was a lot better than an Anderson lpk that had. I would recommend getting one , the brace is usually $129 , for the money this is a great deal.

I highly recommend this Lower Build Kit. Great product at a great price point. I will buy more of these kits for my other pistol builds.

The end cap is branded PALMETTO instead of SBA.
The end cap of the brace is branded with the Palmetto State logo as opposed to the SBA brand name. It is also bulk packaged and not in a retail box. Other than that it functions great. Just wish it were an actual SBA retail part or that it was stated in the description.
Retail SBA3 brace, without Palmetto logo on tail cap.
Branded with Palmetto logo, not SBA logo.

Great Kit
This kit had parts separated and was well packaged. The magpul grip and guard were a bonus for me since i had only paid attention to the brace itself.
