UPDATE-
Got the 10.5 Nork in the mail,...took it out to the shop and put a 3x9 Red field Revenge Scope on. lazer sited it, then off to the range. Set my Target up at 50yards,..after 10 more shots to dial it right in, was getting 1/2 inch groups with ease. Very Impressed !! Set my 8inch steel swinger up at 100 yards,..very easy fast shots. I don't understand it......my 14inch CQ wasn't this accurate. Anyway, the gun cycled and extracted all the ammo 100% I didn't really find it any louder than my 14 barrel. No real muzzle Flip either. I was not expecting to much out of this very short cabine, wow I love it !! This cheap CQ worked way better than my expensive Semi auto Hatson today, "that's posted in another thread.
Update. tried shooting the steel pigs at 300 yards today. Had to aim aprox 6 inches over top "hard to tell from that distance" But it slowly toppled them. My 15 inch CQ was dead on, no elevation required. I'm impressed and surprised with this short boom stick.
