So I’ve tried everything. I am trying to do my teammates rifle for him. It is an Echo 1 XCR-C. I just replaced the shell with a Lonex Shell due to the original not being milled correctly. However, this is everything I’ve done and I am at a stand still. What would you guys suggest is wrong? I can easily hear something isn’t right. If you need a parts list I can provide one.
•Check pinion to bevel height with half shell off
•Shimmed Pinion to Bevel so it can easily turn and not much vertical movement
•Shimmed other gears normally, then shimmed each gear together
•Gears doin freely in gearbox, just as any of my other guns
•Piston moves freely in gearbox when screwed together
