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
