Single barrel break-action trap shotgun

摘要

The trap gun stock has a projection which mates snugly with a complementary-shaped depression in the rear end of the receiver and is secured therein by a spring-loaded stock bolt which extends through the stock and screws into a stud on the receiver. A latch on the fore-end iron engages a barrel lug to releasably secure the barrel to the fore-end iron. An adjustment shoe at the edge of a latch-hole in the fore-end iron engages the barrel lug to ensure precise barrel positioning. A plastic, resilient, low-friction, heat-resistant stabilizing insert fixed to the fore-end wood engages the barrel to facilitate fitting the barrel in non-contacting relationship in a groove in the fore-end wood handgrip. An extractor/ejector mechanism on the barrel and on the fore-end iron operates when the gun is opened to partially extend an unfired shell or to fully eject an empty shell casing. The fire control mechanism is cocked by opening the gun after the action has been unlocked. An action locking bolt slidably mounted on the receiver is movable to lock and unlock positions relative to the barrel by a swingable bolt actuator which, in turn, is swung by a manually rotatable top lever on the receiver. In unlock position the bolt is clear of the barrel locking groove and allows the gun to be opened, but operates an out-of-battery pin to prevent the trigger from being pulled while the gun is open.
