Spyder tl-r with tourament grade 14 in barrel.......stock bolt
Does not chop paint
On old guns can stick in rapid fire
Ok the bolt is good but i recomend it for new guns less than a year because for some reason it fits really tight on my year old spyder tl-r, and after lubing i go to rapid fire and the bolt sticks forward.......I do not know Why.............Today i tried to go to three rivers painball to see the gun tech guy but he wasnt there so untill the this is what i have to say..
Overal good bolt, but its not good for guns a year or more
For new guns overall rating 9/10
For 1yr or more old guns 4/10
