how do you mean slip? as in the pins that hold the back on bent?
Yeah, exactly. The stock cylinder broke that way, but I expected that to happen.
just use a 150 that should be plenty of FPS and range for you. i know it was for me until something got messed up in my gun and the spring got compressed
Edited, I guess this is kinda like a bump. I hope I dont get in trouble for this. :?
oK first off what kind of spring did you have ????? im running a 170 and i have no problem
"1 shot 1 kill"
Do the pins run all the way throgh, and I didnt know they could even come out.
