Great BCG and nitride coating, nothing crazy special, it runs well and can even handle the shittiest ammo (that’s right, steel cases ones). I ran about 1000 rounds through, still looks great and Nitride coating is holding up well.
PSA has been going down hill with their product quality. I am not sure what problems they got going on in there but I've been buying from here for past two years and I never had any complaints but now. The products are lacking quality, I received some parts that were damaged and shipping time has been way longer than it should.
I am not sure about experiences others are having with PSA but I had good experience with PSA. My order was delivered in decent time. I got a BCG from my AR build. I put couple hundred rounds through. I haven't had any problems everything is in a solid shape.
Horrible customer service. They can't even get my order right. Everyone says this company is the best but they are far away from the best. As a customer I felt like I wasn't taken care of the way they portray their image online.
