What hardware do you recommend for a sling set up for this kit? First time building a AR.
Chuck C on Sep 8, 2018
BEST ANSWER: Vickers sling and any QD mount from reputable maker.
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.
Is this buffer an "H"?
Jeffrey E on May 27, 2018
BEST ANSWER: its a carbine, 3oz.
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..
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
BEST ANSWER: Yes, after you finish milling / drilling your 80% to 100%.
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.
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?

Do these kits come with a trigger guard?
Chuck C on Sep 8, 2018
BEST ANSWER: Yes. They come with a matching Magpul trigger guard
Does this kit come with build instructions?
Danie R on Mar 7, 2019
BEST ANSWER: NO... however... YOUTUBE will hook you up and a newb can assemble one in minutes(with proper equipment)
I recommend the proper punch set and a small brass hammer for assembly. you will also need an ar wrench.. dont try to grab the castle nut with a pair of vise grips.. trust me...
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
BEST ANSWER: Well for starters this is a lower parts kit. Not for an upper.
Now if you're asking if you built the lower with this kit will it work with your upper ... the answer is yes.
Can you switch the colors to a magpul pink?
Rw222222222 on Jan 30, 2019

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
Are any tools required to put all this together on a stripped lower?
Beau S on Apr 18, 2019
BEST ANSWER: Yes. There is a great YouTube video by Larry Potter of Midway USA that is VERY helpful to the beginner. Some of the taps he uses are not likely to be need.
Can this be used for .308 build?
Shawn on Feb 12, 2019
BEST ANSWER: No, it doesn't have the correct mag catch, buffer, and spring for a .308 build.
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
Can I use this buffer tube and spring with a 7.5 pistol upper?
Jason N on Jan 21, 2019
BEST ANSWER: Yes you can as long as it is 223 ar-556
Is this good for a pistol build ?
Jeff S on Jan 18, 2019
BEST ANSWER: Order the SBA3 lower build kit instead. All the same parts but includes the pistol brace instead of the buttstock.

Burtrum on Aug 12, 2018
BEST ANSWER: Yep 1/16 is what I used
Will this work for an AR 9? Striped lower is PSA’s forged piece.
Stoffer on Jun 18, 2018
BEST ANSWER: You need a different buffer and spring. 7.5 - 10 oz with a .308 carbine spring or 9mm spring. Otherwise yes.
So all you would need is receiver and a complete upper for an AR 15 -556 223?
Bob W on Dec 12, 2018
I want to build a semi auto .22 rifle, What a lower receiver and the complete upper you recommend? Thank you!

Anyone know the weight on this build kit?

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.
Will this kit work in a 80 percent lower?
Roger H on Dec 16, 2018
BEST ANSWER: Yes! But you want to make sure you are removing all the metal or plastic you are supposed too. That’s the usual problems with 80% lowers

Good price for MOE based kit
I was very pleased with this kit as the price was good for having all the MOE hardware. The only thing missing would have been an end plate with QD mount.
