2011 PMR leaks from grip above 170fps
My PMR leaks from the grip when I increase the velocity above 170fps. At low velocity it works fine, but once I start to slowly increase pressure I can hear and feel the air coming from the grip, the bolt moves slower, and when I pull the trigger a big burst of air comes through the grip.
Everything is stock. I've tried taking my dwell to 30 and slowly increasing it one at a time like the manual says but it won't shoot at all until the dwell is around 38 and the thing still leaks no matter what.
