Gas vent for firearm

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.

1. A barrel for a firearm, the barrel comprising:
a chamber at a proximal end thereof, the proximal end of the barrel being configured to be at least partially received in mating engagement with a receiver of the firearm; and a gas vent feature formed in an exterior surface of the barrel adjacent the proximal end of the barrel, the gas vent feature being configured to enable high pressure gases vented from the chamber away from the receiver and toward a distal end of the barrel, wherein the gas vent feature comprises at least one channel having a selected depth formed in the exterior surface of the barrel, and wherein the at least one channel comprises a forward end with a tapered depth, wherein the depth of the at least one channel tapers from a lowermost surface of the at least one channel to an exterior surface of the barrel.
