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).
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..
Can I use this kit to assemble an AR-9 80% lower?
Brian T on Oct 10, 2018

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.

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.
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.
Will this work on 7.62x39 upper?
Mike M on Dec 30, 2018

Now if you're asking if you built the lower with this kit will it work with your upper ... the answer is yes.

Will this parts kit work for building a 300 blackout rifle?
XSilentShadowX X on Dec 29, 2018
BEST ANSWER: As far as compatability it'll work fine. Although 300 Blackout can be finicky and need some tweaking of the buffer/gas system. A different spring or buffer weights like an H buffer or even H2 may be needed. Although it may work great as is. It all depends on the gas system and such.
Can this be used for .308 build?
Shawn on Feb 12, 2019
BEST ANSWER: You should have no problem. The AR platform utilizes a standard configuration however, the specs from your lower receiver will be where your answer will come from.
Will this kit work in a 80 percent lower?

Bonus for an extra pin detent, but...
Including an extra breakdown pin detent was a small cost for a lifesaving gesture. Of course one of the detents shot God only knows where when installing the front pin.

However, this kit loses points on the stock. While it looks like there are QD mounts, there are none. Plus the stock is loose fit on the tube. Commercial stock w/ mil spec tube, why?

Magpul MOE Lower Build Kit
I ordered a couple kits and one was missing mag release assembly (actually came two sets of safety assemblies). I called PSA and they shipped me a new mag release assembly no-charge. I am very pleased with PSA service and the MOE lower build kits are great!
