Complete Case
this consists of the butt stock and the receiver, connected by a bolt. The breech, firing
and trigger mechanisms are laid in the receiver. The breech mechanism consists of barrel
pins, and a bolt handle-operated locking latch, and when open, the locking latch is locked
with a breech catch. In the closed position, the barrel is matched together with the receiver
to the butt plate and side protrusions. This complete set-up is locked by a locking latch. The
firing and trigger mechanisms consist of cocking levers, hammers, trigger levers, release
lug. Hammers are placed on a pin. Cocking follows the barrel movement when breaking the
gun. The safety catch is situated on the crown of the receiver, works in an automatic,
derived from bolt handle movement, and locks the trigger. Control of the crown bolt handle
and the butt stock itself are modified for left handed shooters.
Complete Forend
this consists of the assembled bar and forend. The barrel band supports the barrel pair
and when breaking the gun, it pushes the cocking levers of the striking mechanism.
