Can you add a rail section so that I can install angled fore grip?
Mark B on Nov 28, 2018
BEST ANSWER: You can add a rail section. Just buy one, install it and install your AFG. Or the better option is probably to purchase a M-Lok AFG of your choosing.
do I need a class 3 license to own this?

You can't beat these prices and service!
Fantastic deal, pricing can't be beat. Combined this with an 80 lower, nice grouping, no extraction issues, no jamming etc, and I've mag dumped it a few times with zero issues.

Solid deal. Solid product.
Put the pistol set up on a PA-15 lower I got in a deal a while back. Everything fit together nicely. Shoots great. Looks great. Feels great.
Been great. Put the set up on an PA-15 lower. Everything went together easily and fit snug.

Pistol build
Went together like a model car. All parts fit well, and it functions. Put a KAK blade on it and greatly improved the comfort.joe

Inexpensive doesnt mean poor quality.
Threw this upper on another already completed pistol lower that I also bought from PSA, put the two together and immediately went out and ran 300 rounds through it with zero issues. Can't say that about some of the Daniel's Defense, DPMS, Odin, and Colt AR's that I've had. Everything fits nice and tight. Great truck gun!

Great kit for the money. KAK Blade doesn’t fit perfectly on supplies buffer tube.
Great kit. I hope they offer these again. I bought it on clearance for under $300 and threw it on an Aero Blem lower (PSA was out at the time) and a standard KAK plum lower (it was on clearance too). The standard KAK blade doesn’t slide over it perfectly. Needed to tap it with a rubber mallet to get it over the knurling on the buffer extension; doesn’t budge, though.

Overall build pictured was sub $500.

Awesome kit, great price, fast shipping.
Really happy with the kit. Can't go wrong with the price, and the free shipping. I got it six days after purchase like I said fast shipping. Installed a kak can, and using a matrix arms lower. Will purchase again from you guys.

Great kit if you replace the barrel and use an H3 buffer
I specifically wanted to build an 8.5" AR pistol and bought this kit. The only pat of this kit that comes assembled is the upper rail, barrel nut and gas system. I I couldn't get it to group under a foot at 50 yards. PSA said they would replace the kit only if I disassembled the entire kit and sent it back in. I ended up buying a 7.5" Bear Creek arsenal barrel for $49 shipped and this little guy will honestly shoot MOA. I put my match scope and mount from my rifle on it with a bipod and with gold dot 64gr it is crazy accurate. I couldn't relive it. PSA over gasses their AR's but this one will destroy your bolt and extractors if you do not slow the dwell time with an H3 buffer. it is extremely violent with the incorrect carbine buffer they include with this kit. If you do not putting a little money into this kit, it is worth it. It just so cheap you can't go wrong, Get a KAK flash can too (PSA has their own one too). My 7.5" feels like a 16" carbine now with the H3 buffer and flash can.

Easy build for a first timer
Never owned an AR anything nor built one until a few weeks ago. Easy to do, plenty of how to videos online to get you thru it. Great value with this package as it included everything needed with the exception of the receiver and what ever sights you want to use. Small lower receiver parts bagged in groups as needed for each area your assembling made it easier also. Get a set of roll pin punches, take your time and have fun.
Used an Anderson AM 15 lower on this one.
