Abstract
A bolt carrier for use with the ARI5/MI6 family of firearms is provided. The bolt carrier includes an integrally formed carrier key and spherical strike face surrounded by a cylindrical counterbore made with a downward angle to act against the tilting force imparted by the operating rod of the firearm's gas operating system. The outer surface of the carrier includes upper and lower running rails that all extend fully to the front face of the carrier to lengthen the carrier's rail support or bearing surfaces against the receiver.
Claims18
A bolt carrier for a gas-operated automatic or semi-automatic firearm comprising an elongated generally cylindrical body having a forward end with a front face, a rearward end, an upper exterior surface, and a lower exterior surface, said upper exterior surface having an integrally formed carrier key and strike face with a counterbore to support an operating rod in contact with the strike face, said strike face and counterbore being downwardly angled.
A gas-operated automatic or semiautomatic bolt action firearm comprising:
- a receiver;
- a barrel coupled to said receiver;
- a bolt carrier with a bolt assembly configured to be received within said receiver;
- a gas operating system with an operating rod for
- displacing the bolt assembly when the firearm is fired;
- said bolt carrier including upper rails and lower rails for contacting said receiver, both said upper and said lower rails extending up to a front face of said bolt carrier;
- and
- said bolt carrier including an integrally formed carrier key having a strike face oriented to be contacted by said operating rod when the firearm is fired to effect said bolt assembly displacement.
A gas-operated automatic or semi-automatic bolt action firearm comprising:
- a receiver and receiver extension;
- a barrel coupled to said receiver;
- a bolt carrier with a bolt assembly configured to be received within said receiver, said bolt carrier having an enlarged fluted boss at a rear end thereof;
- a gas operating system with an operating rod for displacing the bolt assembly when the firearm is fired;
- and
- said receiver extension including drain holes in a bottom and rear thereof through which water is pumped out of the receiver extension by reciprocating action of the bolt carrier during said bolt assembly displacement.
An automatic or semi-automatic bolt action firearm comprising:
- a receiver;
- a barrel coupled to said receiver;
- a bolt carrier with a bolt assembly configured to be received within said receiver;
- and
- a gas operating system for displacing the bolt assembly when the firearm is fired, said gas operating system including an operating rod made of super alloy with a nickel content of between about 15% and about 22% by weight of a total material composition and a cobalt content of between about 5% to about 15% by weight of the total material composition.
