Review:
I dont really know what to say about this bolt that hasn't already been said. It is as efficient as the Evolve bolt kit but is much quieter, and has even less kick. Not to say that these markers have much kick, but this literally has none now. I lent my gun to a buddy last weekend and he was saying that it was barely audible to people standing beside him.
They are hard to find ( much harder than the Evolve), but well worth the money if you can find one.
The only thing that bugs me with this bolt is the reassembly as the sleeve sits farther back and the bolt tends to fall apart as you go to insert it back into the marker. I do it in two parts now.
