I received my special-built PSC-11 a few months ago and it shoots fantastically! Since the base rifle is already awesome and my build took it even farther, I found little to mess with. I did add an IWC swivel back plate, a Phase 5 ambi release, an ERGO Suregrip, and swapped out the black TI-7 to and OD one since looks matter too (keeping with that theme I coated an ACOG as well). This is my setup and it runs great (ACOG is one notch too far back in these pics).
BTW, JP's video on gas guns had some really good tidbits. Moreover, JP was very entertaining!
