Had PP installed in 25 impact last spring. Now its popping back thru the valve in the magazine dock area. What exactly is broken in this contraption? Hoping I can get oring/ seal before I tear it down.
The o ring at the end of your valve rod that seals to that stainless round plate directly under your brass barrel thimble(if you look into your mag slot), has blown out. It’s the tiniest o ring in the impact platform.
