Ummm... bolts on Rebel '02 Xtreme, and Kingman Spyder
Piranha VTL G2 with botomline & Bob Long 4 stage expansion chamber, (green bolt), Rebel '02 Xtreme w/aftermarket Spyder barrel, Kingman Spyder w/bottomline, expansion chamber, with an aftermartket barrel.
works pretty smoothly, 3 o-ring design, annodized, uses tank o-rings, its pretty light
scrapes at the rear end of the bolt on the bottom, not delrin.
This bolt was already in the marker when I bought it, but I am not sure that it is stock because I did not by the marker brand new. I really didn't know the difference that this bolt made in my marker until I started switching bolts around from other marker systems. I just like the way that it is setup with the bolt pin actually removable from the green bolt itself. Spyder don't offer this kind of construcion. It fires very fluid-like, and I have never chopped a single ball. It has never jammed on me, but I am a little worried about the firction wear in the rear end of the bolt. I will probably upgrade to a delrin bolt later.
This bolt is great as a stock bolt if you are receive it as one. If you find it for a decent price and would like to upgrade, I'd say go for it, but if you are really in the market for a smooth bolt, I recommend just going for the delrin
