Suppress that badboy for even more fun.
Warning...pedantic explanation:
The overall configuration is setup to (in order of priority), a) make it mirror my two main 2-gun rifles (a 12.5" and 16"), and b) keep it Title 1 for convenience. In order for a) to be successful, I have the 10" rail for matching ergos and a 9mm brake which pretty closely matches the recoil impulse of my go-to 12.5" 5.56 gun. The delayed blow back design is still a little snappier than 5.56, but the brake and barrel length make it pretty damn close.
Because of all of that, and since I only own one pistol can, I don't really have a way or need to suppress it. Yes, I could cut the barrel down and put it on an existing Title 2 lower, but meh. It works so well as it is. Since it's a training gun, I just ignore the barrel length vs caliber elephant in the room. Unfortunately, a PCC is the only way I can work dynamic movement with a rifle or rifle/pistol right now due to my old range closing.
This is a 416 - yes? (HK upper at least?)
Nein. It's a CMMG Delayed blowback URG with a Centurion Arms C4 rail.
