Will this kit build an AR 10 lower it doesn't say if it's for ar 15 or ar10 it just says miles spec I assume it for ar 15 but not sure?
Ronnie C on Apr 12, 2018
BEST ANSWER: For an AR 10 you will need a different buffer spring, a buffer that weighs 3.8 ounces, and an AR 10 specific bolt catch. Of course you will also need an AR 10 lower reciever. Usually all the other lower parts are interchangeable, but not always depending on the manufacturer. You may be better of to get an AR 10 lower build kit right from PSA and build it on a PSA AR 10 system. PSA is an awesome value and you can deal with just one company. If you are buying this to go in some other pattern AR 10 lower, say DPMS, then this would still be a good deal on a kit, you would just need to by the AR 10 specific parts listed above. I just did this very thing using a DPMS pattern polymer lower from another company and a mil spec parts kit from PSA. I love PSA. I got the buffer and spring from Primary Arms and the Bolt catch from Brownels.
What hardware do you recommend for a sling set up for this kit? First time building a AR.

Can this lower build kit be shipped directly to me?
Daniel F on Jun 13, 2018
BEST ANSWER: Yes, nothing in this kit is a controlled item (at least at the federal level).
Is this buffer an "H"?
Jeffrey E on May 27, 2018
BEST ANSWER: its a carbine, 3oz.
What caliber is this for?
GoatMan on Apr 19, 2018
BEST ANSWER: Build kits are platform specific, but not necessarily caliber specific. This is designed for use on the AR-15 platform, but could be paired with an upper receiver which has a caliber of 5.56, 300 AAC, .22LR, etc..
Will this kit build a complete lower receiver?
Billy S on Apr 15, 2018
BEST ANSWER: Yes, this is everything you need to turn a stripped AR-15 lower receiver in to a complete lower.
Can I use this kit to assemble an AR-9 80% lower?
Brian T on Oct 10, 2018
Does this have an ambi safety lever?
Colin T on May 1, 2018
BEST ANSWER: This kit includes a classic lower parts kit which is not ambidextrous. You can find an ambidextrous safety selector such as the ARMASPEC 90 DEGREE FULL THROW AMBIDEXTROUS SAFETY SELECTOR in the AR 15 lower parts section of this website.
Is this a rifle or pistol kit?
M. C on Jul 18, 2018
BEST ANSWER: This is a rifle kit unless you are building a short barrel rifle.
Do these kits come with a trigger guard?
Chuck C on Sep 8, 2018
BEST ANSWER: Yes. It's in the picture right in front of the pistol grip.
Is it a single position buffer tube?
john a on May 11, 2018
BEST ANSWER: It should be a 6 position that’s how mine are and I’ve gotten a few of those kits they are pretty nice
First time trying to build a rifle as a Father/Son project, something that he can look back on after I’m gone, is this a good starting point, what else do I need to get or should I just buy a bigger PSA kit?
Michael D on Nov 7, 2018
BEST ANSWER: This is a good kit to complete the lower reciever but this kit is not a complete rifle kit. You will also need a lower reciever and all the parts to complete the upper reciever ( upper reciever, bolt carrier group, barrel, gas tube, etc.). PSA has some larger kits that include everything but the lower reciever. Those larger kits are better if you are not customizing your rifle. In the end you will save money with the larger kit.
Is the buffer tube mil-spec or commercial outter diameter?
NANAM on Jul 25, 2018
BEST ANSWER: Hello this buffer tube is mil-spec in dimensions
Will this lower work for the PSA 20" .224 valkyrie 1/7 SS upper?
Lyle Book on Jul 1, 2018
BEST ANSWER: Absolutely and I recommend it 100%. This lower will work with many calibers.
6.5 Grendel
.300 Blackout
.224 Valkyrie

This is just one reason why the AR-15 platform is so good.
Will this work for a 6.5 Grindel ?
Tim C on Dec 8, 2018
BEST ANSWER: Yes it will work for for the 6.5 grendel. The AR15 lower and build kit will work on the 6.5 grendel but you will need a different magazine for the 6.5 rounds.
Hi there, buying this kit for a friend - and apparently know nothing, and can't get my call to go thru to PSA to ask - hoping you guys can help me: What else do i need to pick up to make this kit complete and ready to go? I have it paired with product 598, is there a magazine i need... and? (Thanking you in advance)

PSA 10.5
PSA 10.5" Carbine-Length 5.56 NATO 1/7" Nitride Classic Shockwave Pistol Kit, Olive Drab Green - 5165449225
BEST ANSWER: You don’t need product 598 with this kit, in fact the way I understand the law, you cannot legally attach the buttstock in 598 to a pistol. Buy a stripped lower like the one on sale today and a magazine or two, and you’re all set.
Does this lower build kit come with the polished trigger control?
Pete B on Sep 13, 2018
BEST ANSWER: Its a standard milspec fire control group.
New to building. Will this work with a 20 in barrel or will i have to change out the buffer tube and spring?
H G on Jul 9, 2018
BEST ANSWER: Just fine. Barrel length has no determination on buffer tube and spring in regards to ar furniture.

As long as This is going on an ar-15 and not an ar-10, it will function flawlessly.
do you need a different buffer spring between rifle gas systems and carbine gas systems ?
Kyle K on Jun 7, 2018
BEST ANSWER: The spring should run fine with both the buffer you might need to change out but not likely though. I've used the same spring on my ar rifle and my ar pistol. No issues with the spring
Will this work on the pa-10 lower?
Brett A on Jun 3, 2018
BEST ANSWER: No sir. Ar15 setup. The grip will work. But you can get separately.

Burtrum on Aug 12, 2018
Is this a rifle buffer tube or carbine buffer tube? Will this go on a rifle length gas system.
Matthew J on Aug 14, 2018
is this kit able to ship to NYS?
Ian K on Jul 20, 2018
Can I use the parts on a stripped lower for a pistol build? I know I can't use the stock but will all the other parts work? I'll just put the stock on my other rifle
Gaige B on Jul 2, 2018
Is this kit come in other colors? My wife wants PINK camo.
Tom S on Jun 22, 2018
Will this work for an AR 9? Striped lower is PSA’s forged piece.

Great parts kit I can’t say much about the trigger because I installed a 3 lb drop in but I put the trigger group together in another lower and seemed to fit up well together

Should be a negative Star
Bought this for a budget build I was planning a few months earlier than I started. It seemed to have everything I needed so it fit the bill. In doing the build I found that the pivot pin and take down pins were too thick and wouldn't function properly so I had to go out and purchase new ones. Then the trigger wouldn't even line up inside of the lower so I had to get another trigger also.

It pays to buy higher quality parts even for a budget build.

Easy Enough I'd Do It Again
This was my first build but I am very pleased. Ordered after hours on a Friday night and it arrived on Tuesday. I'm not the best/fastest handy man but the kit was fairly stress-free to assemble over a weekend with help from the Great Equalizer (YouTube). Thank you PSA.
