摘要： A feed ramp system for feeding cartridges into the chamber of a firearm. The feed ramp system includes a feed ramp insert having a body with at least one attachment tab projecting therefrom. The feed ramp insert is received within a mating recess formed in the receiver and is removably coupled to the receiver to enable replacement of the feed ramp insert. The feed ramp insert includes a pair of proximal ramp surfaces that align with distal ramp surfaces form at a breech end of the firearm barrel, to define a pair of feed ramps for directing cartridges into the chamber.

摘要： A barrel and a barrel extension for being coupled to a firearm. The barrel extension can be threadedly engaged with a proximal end of the barrel. A chamber of the firearm can extend in at least the proximal end of the barrel. One or more channels can be formed in the exterior surface of the proximal end of the barrel and/or the interior surface of the barrel extension for providing fluid communication from the chamber to the forward end of the barrel extension between the barrel extension and the proximal end of the barrel for venting high pressure gases that may develop in the chamber.

摘要： A biasing member for a bolt assembly of a firearm is described herein. The biasing member comprises a body having a first portion configured to engage and seat within a biasing member receiving indentation of an arm of the extractor, and a second portion configured to engage and seat within a receiving area along a bolt of the firearm. The body provides a biasing force directed against the extractor arm. The body comprises an elastomeric material, and is configured such that the first and second portions provide varying levels of compression sufficient to maintain a substantially constant extractor tension between the extractor arm and a cartridge.

摘要： A muzzle brake assembly for a firearm provides several benefits including an ability to reduce firearm recoil by redirecting the propellant gases and reshaping the pressure wave in a new manner, reduction or substantial elimination of muzzle movement upon discharge, lessening the acoustic signature of the firearm closer to non-braked levels and relatively easy and low cost to manufacture by current machining practices thereby minimizing cost of manufacturing. Ports in the muzzle brake assembly are arranged opposing one another about a circumference of the muzzle brake assembly.
