this is a lathe turned .25 trail xl barrel (done by troy in GA). it fits snugly into the disco barrel bands. cometa 400 compact "pickle" works great. built on a 2250xt base. my question is : how much hpa pressure do you think that feeder tube, or co2 channel that takes the pressure around to the front, can handle ? steel allen screws go into the steel plug in the back, but the front screw threads into the brass valve. goes in about 1/2". this tank is reg'd for a refilling the disco - 2000 psi output. i'm dying to try some shots, but i am enough health problems lately. take a look and please leave some feedback if you have insight or experience. - paul d self. http://raneair.webs.com
