The Gen2 PA10 receivers are functionally compatible with the Gen1 upper receivers, however we recommend matching Gen2 lowers to Gen2 uppers for best appearance.  There are external cosmetic differences when mixing Gen1 and Gen2 upper and lower receivers that some may not find appealing.  Gen1 lowers will be available in the future for those who want a cosmetic match.

3D M on Aug 19, 2018
BEST ANSWER: I have that exact lower and it fits perfectly minus 2 things. Takedown pins. Buy the extended ones anyways because they’re super nice and that’s all the modifications you’ll need for the Warthog
Is ghis a complete rifle kit or does it require other components?
John L on Jul 18, 2018
BEST ANSWER: This is a complete upper PA-10 and lower parts kit. The lower is incomplete. You will need a stripped lower receiver to complete your rifle. PSA has all that you need to complete this build.

How difficult would it be to change the mid length hand grips to full free floating?
James B on Aug 1, 2018
BEST ANSWER: Not hard if you've done any already on AR-15 type. If not, it's best to have a few tools. A sight block, tapered pin punch for AR, and an armorers wrench. You will need to remove the muzzle brake, then drive out the tapered pins that hold front sight. The tapered punch is concave to fit over the pins making driving them out easier. Using armorers wrench to remove barrel nut in order to replace with nut supplied with free floating set up. Look for installations videos from manufactures websites. Brownell's sells the tools needed.

I love the big brother look the AR-10 has on the AR-15. I wouldn’t mind going another build but the stainless next time just for the looks.
I’m in California so I have to comply with the laws. I tried installing the Hellfire kit with no luck I couldn’t adjust to make it work right so ended up installing on another ar-10 I have. I got the muzzle brake, handle, now just waiting on optics to come in. So I haven’t had a chance to break it in yet. I do like the kit , was torn between this one and the stainless kit. I am happy with my choice though. I wanted an AR with more muscle than an AR-15 now I have it.
Just waiting for optics to go to the range and break this bad boy in.

PSA Made it right.
I Ordered kit on 8/1/18 and received on 8/14, proceeded to the range same day and that's when problems arose. Spent shells weren't ejecting properly or turning 180 deg and getting stuck. I took the BCG from my PSA Gen1 308 and it worked fine. I put BCG from this kit in older rifle and it had the same eject issues. PSA gave me a return authorization and received the upper on 9/12. It was back to me on 9/25 and at the range 9/26. It worked perfectly. PSA didn't tell me what repair was done, but it appears to have a new BCG in it. I have always had good luck with PSA 5.56 kits, this is my 4th 308 build. I am a fan of PSA, and it's quality and workmanship

Good kit, good customer service.
Ordered this kit and it arrived very quick. Lower parts kit was nice and it is a nice upper. But the upper I got had a Blemished barrel. The nitride treatment didn’t take right and had spots all over.
That being said the Customer service dept set me up with a return label for Replacement the same day, after emailing some pics to them. And am currently waiting to get the repaired/replaced upper.
So if not for the barrel, this kit would be AWESOME. But it’s being taken care of so 5 stars. Will update the review when I receive the new/repaired upper.
Thanks PSA for having a pretty decent customer service and taking care of me same day. Can’t wait to get my new upper back and put some rounds through it.

Worth the money
Well made, great priced bargain! My only recommendation (warning) IS: Use ONLY the PSA PA-10 lower receiver with this kit.
The PA-10 308 upper / barrel kit may not work with other lowers. I'm in the Republik of Kalifornya, so I cannot buy PSA lowers. I'm stuck with buying what is on their approved list. I bought an Aero Precision lower and it wont accept the PSA upper. Oh well! I now need to explore other (legal) options.
