Smooth as silk (27/02/2010)

True drop in performance upgrade for the AR-15 rifle. Helps the gun cycle fast and smooth. A noticable difference that you can feel everytime you shoot.

I'm betting my life on it! (22/04/2011)

I have just finished a new build and it is showcased with a JP trigger group and a new stainless tactical bolt carrier. The bolt carrier is flawless in appearance.It is smooth as silk in operation, and wipes clean in a swip. Forget the rest, buy the best!

smooth,smooth,smooth. (12/06/2014)

I originally was going to go with piston but the kit I received had wrong part and didn't want to risk waiting on another to find it was a messed up kit also (from the factory) so then to choices, I thought about the new finishes but also knew sp quality and read reviews everywhere and all were the same so I went with it and it's everything they say,just smooth.The gun now has a 22"jp 6.5 grendel barrel,jp gas block (not worth the extra) jpbarrel cooling fins/not light and a vltor mur upper with a sig lower, sig lowers from 516's are perfect match and thick..
If you are wondering what dif the carrier made I will tell you, it slides easy with no metal sounds rubbing against each other it just glides making it a simple smooth as glass charge.
I am glad I got this carrier it's the best I have seen.
