The 2A Armament Keymod rail has some play in it. It wiggles a little when I grab the rail. Is this normal or something to be fixed? Thanks.

Definite " Buy " on this one
I bought this variant of the 300 Blackout as a " Black Gun " for my wife. Protection and hunting purposes are its duties. She loves to hunt and shoot and fell in love with the present I have her. I mounted a rangefinding reticle 2x - 7x X 28 scope on her weapon and got it on paper - then she dialed it in. The pistol is quite accurate. Much more so than I believed the 8.5" barrel would allow. She then loaded a fresh 30 round Magpul magazine and proceeded to fire shot after shot about every 1-2 seconds until empty " killing " the 8" shoot and see target DRT. It has had ZERO jams or malfunctions and it has become her new " favorite " gun. I am pleased enough that I am going to buy myself one just like it or get the 10.5" variant.

Thanks for an awesome product at a great price / value. Hopefully I'll be able to save enough to buy a few more of them! Everyone in the house wants hers..... I do however believe we will be changing to a Nickel Boron coated BCG and charging handle and I may get her a 3.5 to 4 lb. Nickel Boron coated drop in trigger set. I can only imagine how great the setup would be then!! Thanks PSA - it's a winner.

Nice weapon... great price
My first PSA order and it was a good choice. This weapon has a solid feel. Very light weight and comfortable to shoot. I was expecting some compromises due to the price but it turns out it is very well made. Trigger feels solid no rattles or looseness in the fitting of parts. Cycled subs and supers without issue. Very pleased with this purchase. My only negative would be the edges on the metal mag feel a little sharp so be careful when loading.

Good gun bad magazine
This 300blk pistol is awesome! I got it on sale for $499.99 which is an excellent deal. Quality parts and build for sure. It cycles with no problems and is a blast to shoot.

The only complaint that I have is the awful little aluminum magazine they send with it. It absolutely would NOT feed a round under any circumstance. I didn't try anything other than Remington 120 grain fmj so maybe it just doesn't like those. I popped in a Gen M3 PMAG and that worked just fine though. I'm probably gonna have to bend or file down the ears to make it work at all.
