Prevents Barrel Roll-Out in closed bolt markers, like Autocockers and Cocker Pumps.

The Breech Sizer will center the ball ensuring an even cushion of air around the ball before it enters the control bore of the barrel. This produces optimal accuracy and gas efficiency than with the barrel alone.

Product pictured is a .687 Bore but this product is for a .678.
