Retro Valve trouble

[markskee]

I just bought a brand new RetroValve yesterday and it
spits when you hold down the trigger after a shot, It
also will get a bit of bolt stick. And what length on off pin is the one that works best with a strandard power feed mag? Please help any info on how to set up the retro would realy help.

Frist, make sure everything is well oiled. Then you could try a different powertube spacer. And dont worry about the on off pin. It should be fine.
