killshot

Thanks for the reply. I only changed the return spring. I lubed the cup seal, and it moves smoothly, it's just like the spring doesn't have tension until it's stretched far out, and it's not snappy return like I see in everyone's videos. I don't think it sticking in the bucking is the issue, as when the bolts removed it's sluggish there. Also gas efficiency on a 10 second charge is like 25 shots max. I'm going to take it apart later today again and just doouble check everything. but I'm not sure what to look for now.

Hey All, I recently got the Dynamic Precision nozzle return spring, got it all installed what appears correct, followed youtube vids etc. and now my fps has shot up to 380. Gas efficiency is meh, and the bolt fails to cycle after about 15 rounds. Also recoil feels punchier, in weight, but also slower. also when removing the bolt, and pulling on the nozzle it's not snappily returning, its rather slow and meh. any ideas or helps to fix this would be greatly appreciated.
