Is the receiver extension in this kit 7075 or 6061 aluminum?
Tolly on Sep 12, 2018
BEST ANSWER: Its 7075 I called when I bought mine.
do these kits come now with your new style receiver extensions with its one sided "stub" for holding bufffer retainer or the traditional (mil-spec)extended bottom lip?
orion on Sep 12, 2018
BEST ANSWER: You should expect mil-spec.
Will this lower parts kit work for a 300 blackout???

BEST ANSWER: Its a rookie question but I think he just wanted to make sure :)
Will this lower build kit for for an AR 9?
j R on Nov 11, 2018
BEST ANSWER: Spring and buffer are weighted for a 556/223 build, but all other parts would be compatible with any mil-spec AR lower with a 9MM mag adapter. Some manufacturers make custom pistol lowers that should still accept this grip, tube, take down pins, and trigger, but the parts like bolt release and mag catch from this kit might not work with those proprietary lowers.
Is this stock collapsible? Thanks

does this have a recoil pad?
tom21014 on Sep 27, 2018
BEST ANSWER: Yes. More than enough padding for an AR15!
Will this kit work on At-10 Recivers ?
Glen D on Sep 24, 2018
BEST ANSWER: The short answer is NO.
There are many parts of the AR15 lower build kit that will work with the AR10, but there are a few that won't. The buffer and buffer spring certainly won't. The take down and pivot pins probably won't. You could buy this kit but then you'd have to scrounge around to source the parts that aren't compatible.
There are plenty of websites that will do a good job of telling you what parts will cross over.
Since there's no 'mil-spec' for the AR10, you may be better off spending some time on hold for the PSA customer support line to get their specifics.
does this have a rubber recoil pad?
tom21014 on Oct 2, 2018
BEST ANSWER: It's rubber but not really a recoil pad. AR's do not kick, you'll be fine.

Solid Kit
Used these kits on Aero and Anderson lowers. Kit typically has extra springs which is a nice bonus. Zero concerns or problems. Parts are packaged based on the installation area (i.e. trigger components are in a separate bag, magazine release parts in a separate bag, etc). I'd recommend you check out Larry on Midway's Utube channel to guide you through a correct install.

very nice at a good price. Unexpected bonus chrome plating on key trigger area. Everything fits as it should. Putting detailed instructions or a youtube link for assembly might be nice.

Super kit
PSA knocked it out of the park and as always, thanks for the extra spring in the kit, that can come in handy!

Great kit for the price
Overall a great kit for the price. I dinged it a star because the safety selector is slightly overfilled, and sticks in safe. But every other part was near perfect.
