for now all i did was angle the transfer port polish it a bit and round the valve stem for smoother flow
i am still going to angle the inlet of the valve for more flow and smoother flow
i also am using a standard 2240 hammer thats been polished and a heavier hammer spring
but i like where it is shoot right now so i might not change alot
i have some BA parts comming in and some crosman parts coming in this week also to finish my disco pistol with an 18 inch bbl and a shorty stock so it can be a takedown gun
i am looking for 30 fpe out of that rig

I;m impressed…with that little barrel getting those velocities…..what did you do to the valve??

well i tested the pistol out tonight man i love hpa in the cold the co2 setup would have been not working
now i went out to the shed to get a few bags of pellets for the pelletstove
i always carry a gun decided to take the pistol
well as i open the shed i hear hisssss and this damn stray cat comes runnin out and stops at 15 yards at the edge of the bushes
i put the fiberoptic dot between its eyes
and POW he flopped and was toast
lol
i had to bag him up quickly as the gun with the shorty bbl is loud
but that thing thumpped the damn cat now i gotta cover the bloddy snow so the wife dont see hahaha
