Truthfully, I was worried about the setup, I wanted to get a Knoxx, but this was 60 bucks versus 150 bucks, when I first installed it, the angle of the stock would not let me see the top of the barrel, let alone the sights, so I took the adapter piece, the very short section, and filed it a little at a time, until the angle was right, and I could see the the sights correctly. The recoil did surprise me, it was about the same as a normal stock, I expected much worse. FWIW
