Abstract
Airguns are provided. In one aspect, a shuttle having a breech bushing therein is moved between a cocking position where a projectile is loaded into a breach bushing channel and a firing position where the breech bushing channel is located between a port from which compressed air flows firing and a barrel opening into which the compressed air advances the projectile. The barrel has a barrel guide surface at the back barrel face, wherein the breech bushing has a shaped surface facing the barrel and wherein the breech bushing shaped surface and the barrel guide surface are configured to interact as the barrel is moved from the cocked position to the firing position to urge the breach insert to move within the shuttle passageway in a manner that reduces the extent of any misalignment between the breech bushing channel and the opening.
