I picked this Gen12 (from Genesis Arms in CDA Idaho) in mid February and shot it a bit to get used to it and figure out what ammo and optics would suit.
This short video sums up is my "train up" until running it for score at a Major 3Gun (SMM3Gun) March 19,20,21.
I have about 1100 rounds on it and had 3 failures (stove pipes) in the first 50 rounds (with the ammo I have chosen).
It uses a Short Recoil system and an "AR like" rotary bolt and carrier.
It truly drops onto a DPMS pattern LR308 lower.
Speed it has (they have a FA gun for demo)
Holds fist size slug groups at 50 yards
It is a clay buster! I have equaled my "A" class scores on the Sporting Clay and 5 Stand courses.
Did I mention it is fast handling? Flying or stationary this (so far reliable) Box Fed 12G is most excellent!
I think I have found my "Practical shotgun"
I will be writing this gun up (with another 1500 through it) for Recoil Magazine.
