KSC USP 45 Tactical
 

I recently cleaned my .45 and when i go to fire it now it will shoot one then one will fly out the shell eject port or fall out the barrel, new hopup rubber so whats my problem?

help please!

happened to me before, lube up the blow back mechanism seems to help with the problem. Another thing is different brand of bbs (apparently 5.95 works better than 5.98...sry that means BBB aint gonna help much.
Another thing is hopup mech is really iffy sometimes..
Try these, they usually work for me.

k will try
thanks

nope still doing it..

did you install hopup buckling properly?
