Title: ROTATABLE FIREARM BOLT
Abstract:
A bolt (50) for a firearm having a rotatable head (58) and carrier body (56) has a twisted and keyed interface between the head (58) and carrier body (56). A neck (57) extending rearward from the head (58) presents the keyed interface with a corresponding bore (55) within the carrier body (56). This construction reduces torque moments between the head (58) and carrier body (56) as compared to prior art bolts. Camming loads on the neck (57) may be constructed with inverses to create space for tolerance and lubricant. Firing pin (54) resides within the bore.
