I was doing some tuning on my impact .30 and this happened.. A hiss of air and after I remove the mag I noticed the valve rod was not flush.. I maxed out my hammer spring and regulator at 160 psi.. Did I screwup the valve rod? Any idea or somewhere to start, on how I can fix it Shooting 49.5 gr NSA at a bit over a thousand and JSB 44gr at 1100 fps..
