So after I did a little Drexel work to my receiver for the forarm tabs to fit up over it I got it all together. I gotta say the pia was worth it. I paired the upper with a JP silent capture spring which is the smoothest buffer system I've found. The Gibbz upper/JP silent spring combo is the smoothest AR that I've ever felt. Even smoother then my $3000 factory JP CTR-02. I don't have one of the JP side chargers but I'm assuming that the lack of lateral torque on a charging handle is the cause of the smoothness.

Here is the finished rifle. It's my 6.8 SPC SBR with a Silencerco Saker out front. Gonna kill an animal again someday so I figured i might as well donut with style and class as quietly as possible.
