the marker i have this product in is:
was stock, JUST added a WORR Hindge Traigger frame,
planet eclipse On/Off Purge & Mini Rail
J&J Ceramic 14 inch barrel,
KAPP Twisted Cocking rod,
Coopet-T Delrin Bolt(this guy is pretty unknown and has a GREAT product),
otherwise the rest is stock.
i usually use a dye trottle 91/45tank
only BLACK availible
This bolt is great, it is light and fast, lets my cocker rune at a lower FPS(saves air), looks great(all black marker,mostly) and was hella cheap. this cooper-t guy know what he is doing, and wht he did was designa great bolt and then produced a quality bolt, and all at a very reasonable price. when persons check out my marker it is one of the first things they really eyeball(i have yet to see another one in play).
i dont have the scientific proof or testing but i believe i made my marker quieter, faster, more efficent, shhot farther, and become more accurate.
this is a GREAT bolt at a GREAT price.
Cooper-t bolt.....We only use autocockers. The cooper-t bolt shoots better than anyother bolt for the autococker. This bolt shoots a paintball 10 yards further with accuracy than stock or after market bolt. I can hit targets at 60 yards with an 18 inch circle. You can only shoot 12-13 rounds per sec...but that is all you need to take out your target!
