Honestly, I've never had a fixed-stock on an AR (except an M-16 a long time ago).... but I've struggled with a good cheek weld, and I hope that this solves the problem.I'm currently looking at setting up my Tippmann 22 and my 18" Noveske both with fixed stocks. The Tippmann currently has a UTG A2 rifle stock kit and I had to add a spacer in the tube for the action spring/buffer. That added some weight and I really like it now. I'm trying to decide if I want to put an A2 stock kit on the Noveske also, or go with something nicer like the PRS (but then that doesn't match the Tippmann). I've had the Magpul MOE rifle stock in the past, so maybe I go that route as a happy medium for both rifles. Decisions.
