One thing I noticed when I switched out the stock bolt and replaced it with the Boss bolt, was how the Boss bolt shot quieter and there was less recoil with each shot. Each shot seems to have more a muffled sound. Also with the stock bolt you could definitely hear a metal click with each shot, the Boss bolt eliminated that metal to metal clicking sound. I have not had a chance to check if the bolt has made any changes to my velocity, but by the way I was hitting my practice targets at the usual distance I believe it has increased my velocity by a few FPS.
I really like how this bolt performed. I have not tried any other after-market bolts, but it definitely works better than the stock. Overall it made my maker shoot quieter (just a bit) and I can shoot much faster without experiencing the usual recoil, in other words my marker shoots steadier and its easier to keep your aim on your target. Was not disappointed.
