5.2. OPERATION
FNH USA bolt-action rifles operate by lifting the bolt handle, drawing the
bolt rearward and then sliding the bolt forward and rotating the bolt handle
downward until it stops. This process takes a cartridge from the magazine
and loads it into the chamber for firing. When the trigger is pulled, the
firing pin strikes the primer of the cartridge, resulting in the rifle firing.
During the rearward movement of the bolt, the empty cartridge case is
ejected out of the ejection port.
Most FNH USA bolt-action rifles
(except TSR XP USA, 223 Rem.)
feature proven Controlled Round Feed
(CRF) with a claw extractor (Figure 2).
The extractor secures approximately
¼ of the cartridge base and fully
controls the cartridge as it enters the
chamber. This design also allows the
cartridge to be extracted even if it is
not fully chambered.
