i dissagree,there is a slight differance as it guides the ball that little bit more.you need 8" of unported barrel to excelerate the ball,and 4"minimum to guide it, more will help stabalise it,but also slow it down due to friction.anything above 16/18" wastes gasOriginally posted by P8ntbllr99
14-16 will not improve your accuracy it doesnt matter above 12" accuracy wise
