black dragun patriot with carbon fiber barrell, delrin bolt, ACI 44ci 3k air tank and 12 volt revolution hopper
it really helps with the snow comin gout of the barrell on cold days. It looks good and offers a good front grip.
i tlowered my velocity by quite a bit after I put it on my spyder from 280 to about 240 the reason being that the flow is so constricted(which is what an expansion chamber is supposed to do) so i tdoes not allow enough air into the volumizer to push the ball fast enough. this also leads to some shoot down after each shot.
This is a very good product with only some small disadvantages to it but still definately worth the thirty bucks I paid for it.
