Assemblies, methods, and/or the like are provided. In some embodiments, a barrel assembly includes a barrel defining a bore extending therethrough between a receiver end of the barrel and a muzzle end of the barrel. In some embodiments, the barrel defines a threaded outer surface at the receiver end. In some embodiments, the barrel assembly includes a barrel extension defining a tapered outer surface and a threaded inner surface. In some embodiments, the threaded inner surface of the barrel extension is configured to engage the threaded outer surface of the barrel, the tapered outer surface of the barrel extension is configured to engage a tapered inner surface of an upper receiver.

Abrégé

A firearm barrel is provided having a body defining an outer surface and a bore. The bore may define a rifling profile along at least a portion of a length of the barrel. The rifling profile may define a cross-sectional profile perpendicular to the length of the barrel at a location along the length of the barrel. The cross-sectional profile may include a plurality of arcuate portions and a plurality of linear portions. The cross-sectional profile may define a cross-sectional area defined by a Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) standard rifling profile. Various embodiments may include firearms, assemblies, components, and methods associated with such firearms and firearm barrels.

Abrégé

An assembly for directing propellant gas to an action of a firearm includes a barrel and a gas block. The barrel has a plurality of gas ports that communicate with the bore of the barrel. The barrel and the gas block define a passage that receives pressurized propellant gas from the bore by way of the barrel gas ports, and directs the propellant gas to a gas port of the gas block. The plurality of barrel gas ports and the passage act as a manifold in which the propellant gas is taken from multiple locations within the barrel, combined into a single flow, and directed into the gas block via the gas block gas port. The pressurized gas is then routed to an action of the firearm by way of a gas tube and a gas key.
