Abstract

A barrel break air gun includes a pair of opposed, generally planar faces defining a narrow gap between the breech and the barrel. The barrel face includes a circular groove concentric with the barrel bore that receives an annular seal, and a recessed annular land defined between the circular groove and the barrel bore. The annular seal may be either an o-ring nominally disposed within the circular groove, or an annular urethane washer that is slightly radially-compressed when placed into the circular groove such that the inner diameter of the washer projects slightly away from the barrel face prior to closing the barrel breech. In one embodiment featuring the annular washer, the washer's internal diameter is slightly smaller than the maximum skirt dimension of an air gun pellet, such that the pellet's skirt is retained by the washer upon closing the barrel breech.
