摘要： A muzzle accessory assembly is provided. The assembly includes a muzzle accessory having a main body with a proximal end, a distal end, a through-channel extending longitudinally between the proximal end and the distal end, a keyed receptacle within the through-channel, and a slot, and a lock within the slot of the main body, the lock being positionable into an unlocked position and a locked position; and a firearm barrel within the through-channel of the main body, the firearm barrel having a chamber for receiving a firearm round, a firing tube extending distally from the chamber, and a coupling engaging the keyed receptacle of the main body, in which the firearm barrel is removable from the through-channel of the main body when the lock is in the unlocked position, and the firearm barrel is locked longitudinally and rotationally within the through-channel of the main body when the lock is in the locked position.

摘要： A wipe-cutting tool integrated into a firearm or firearm accessory, or component thereof, which can be replaced in the field. The muzzle accessories may include a suppressor, a brake, a compensator or a flash suppressor. The components may include an endcap, the end of an accessory, a muzzle or a baffle. Cutting blades are integrated into the firearm or muzzle accessory and may be integrally formed with the suppressor or compensator tube as well as with a muzzle end cap attached to the tube. When pressed into a substrate of material suitable to form a wipe the cutting blade separates a wipe from the substrate which can be readily inserted into the suppressor or compensator at the muzzle end.

摘要： A recoil compensator for a handgun defines a through opening along a central axis, the through opening including a threaded portion configured to threadably engage the threads on the distal end portion of the barrel. The recoil compensator further defines a port in a top wall and defines fastener openings each configured to receive a taper pin. When the recoil compensator is installed on the barrel, the central axis is substantially coincident with the bore axis and the port is configured to vent a portion of propellant gases from the barrel upon firing the handgun. The threaded portion threadably engages the threads on the barrel with a distal end of the barrel positioned proximally of the port. Each taper pin is received in a respective fastener opening and engages a side of the barrel. A slide assembly and handgun including the compensator are also disclosed.

摘要： A muzzle brake apparatus comprises a main body having a central bore and a plurality of peripheral bores about the central bore, the central bore extending a flow path for a projectile from a barrel of a firearm and an exit for the projectile and a brake backing plate coupled to the main body, the brake backing plate constructed and arranged for coupling to a distal end of the barrel of the firearm, the brake backing plate including an air chamber that provides an interior volume for receiving a flow of gas in the flow path of the barrel, wherein the peripheral bores output a first portion of gas from the firearm, and wherein a second portion of the gas is returned to the barrel from the air chamber.

摘要： A blast attenuation device (100, 1100) for a gun tube (10). The blast attenuation device (100, 1100) has a first wall section (102, 1102) which defines a first chamber (104, 1104), which extends from an inlet end (106, 1106) having an inlet aperture (108, 1108) to an outlet end (110, 1100) having an outlet aperture (112, 1112). The blast attenuation device (100, 1100) also has a second wall section (122, 1122) which defines a second chamber (124, 1124), which extends from an inlet end (126, 1126) having an inlet aperture (128, 1128) to an outlet end (130, 1130) having an outlet aperture (132, 1132).

摘要： Methods and systems are provided for firearm muzzle brakes. In one example, a muzzle brake comprises: a body; a projectile entrance and a projectile exit; a gas-actuated valve biased toward the projectile entrance within an interior of the body; and a projectile opening of the gas-actuated valve arranged along a projectile path between the projectile entrance and the projectile exit.

摘要： A wiped muzzle device, such as a compensator, brake or flash suppressor. The wipe improves the function of the muzzle device by forcing muzzle blast gases through the ports or vents to either counter the force vector created by the muzzle blast gases or alter the mixing of gases to reduce muzzle flash.
