Shot one of these today and I was left a bit let down. The hype I had in my mind was not on par with what I experienced. One thing is for sure though, the gun does manage muzzle control EXCEPTIONALLY well. The recoil and overall feel of the gun reminded me of the HK UMP, but the muzzle exhibited 25% of the climb even with a quick cadence. Still a unique gun, and I'm glad I got the chance to play with it.
