I've got a mechanical mag, with a chimera grip, X valve, Level 10, and ULT. I forget all the details. I know I've got the red spring in there. I can check later. Anyway, it chuffs on the first shot every time. ie, if I shoot rapidly for 10 shots, the first shot chuffs on me. If I wait a few seconds and try it again, it does the same thing. Any ideas on what might be causing that? Every shot after the first one is normal.
Thanks
