Does your Piranha not re-cock? Look here for information!

Ya, I notice the R6 likes to stop re-cocking, then start again after firing a few dozen rounds, and then stop again. Finicky gun.

I had this problem and it was caused simply by a bad spring. When i used a different blue spring than the one that was causing me problems it went away. I even tried the bad spring in a fully mechanical marker instead of my Pro E and in my TS it wouldn't even cock it.
