Accessory mount for a firearm

Abstract

An accessory mount for a firearm may include a tubular body defining a barrel-receiving bore configured to receive a distal portion of a barrel of the firearm therein, one or more mount protrusions disposed on an internal surface of the tubular body and extending circumferentially with respect to a longitudinal axis of the tubular body, and one or more mount channels defined at least in part by the one or more mount protrusions and extending circumferentially with respect to the longitudinal axis of the tubular body. Each mount protrusion may be configured to be received within a respective barrel channel of the barrel when the distal portion of the barrel is received within the barrel-receiving bore. Each mount channel may be configured to receive a respective barrel protrusion of the barrel when the distal portion of the barrel is received within the barrel-receiving bore.
