hey..ok let me start by saying i got this gun used... built by GUMP back in the day...so i have NO IDEA what is inside...
i do know it shoots about 400-420fps with .25s.... and in the 460 range with .2
im looking to get it down to about 360-375 fps.....
and looking at spring charts doesnt help my cause its most likely got ported cylinders or not... or whats going on in there.....
anyone can give me a hand.... and possibly meet up with some springs that would be awesome.....
anyone?
