More pictures of the 62 cal sniper. This shot shows the underside of the 62 cal barrel with the air passage into the bolt. Because of the threads the air passage was drilled uniquely for each 60 cal body.
A shot showing the feed notch cut into the sleeve of the 62 caliber barrel. The feed hole also needs to line up on each body so barrels are slightly specific to each 62 pump.
