it has the as to paintball adaptor, so i use the slim 9 oz pball tanks. i have a 17" .20 caliber lw barrel on it that was lathed down to 7/16" and fits perfectly into the steel breech of the 2250xt. i am only getting 600 fps w/ ftt's and a little less w/ the newer sheridan cylindricals. this carbine has that tube that runs around the outside and brings the propellant into the side of the brass valve. i am using an extra-heavy hammer spring already and a cut piece of ice-maker line for the seal between the outlet of the valve into the rear of the barrel. how can i get more velocity ? how many fps do y'all get w/ your custom modded .22 cal 2250xt's ? - paul. raneintexas@yahoo.com .
