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.

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.

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.

A system and method for attaching a muzzle attachment to a firearm. The muzzle attachment has an attachment body that is defined by an inner surface having a bore along the central axis of the muzzle attachment. The attachment body may include a threaded portion extending a length along the inner surface configured to engage a threaded portion of the firearm. The attachment body includes a lock that is configurable from a retracted configuration to an extended configuration. In the extended configuration, the lock is configured to securely engage a recess of the firearm. By threading the muzzle attachment onto the firearm and engaging the lock with the recess, the muzzle attachment system resists removal of the muzzle attachment from the firearm. The muzzle attachment may include vents. The muzzle attachment system preferably is indexed relative to the firearm for proper operation of the muzzle attachment during engagement of the lock.

An adjustable tuning device includes an externally threaded mounting member having a base defining an aperture and a tuning weight having internal threads configured to mate with the externally threaded mounting member. The aperture can be configured to receive a forward portion of a gun such that a threaded protrusion extends forward of the base. The mounting member can have a rear surface configured to abut a forward-facing shoulder of the gun. The tuning weight is rotatable about the mounting member to move in a range of axial positions with respect to the mounting member and a barrel axis. The mounting member can have a skirt extending from the base. The mounting member can have an external diameter at an externally threaded portion, and the tuning weight can have a rear portion with an internal diameter less than the external diameter of the mounting member.

FIELD: gas units. SUBSTANCE: muzzle brake-compensator (MBC) with a system for interrupting a supersonic gas flow contains a housing, annular elements connected to each other by cutting off chambers with nozzles. The nozzles are united by an internal through channel for the passage of the projectile and the gas jet. In the working area of each cut-off chamber, at least one side outlet window is located so that when the MBC is installed on the end of the weapon barrel, the side outlet windows of each chamber are oriented perpendicularly or at an angle back to the direction of the outgoing gases. EFFECT: technical result is an increase in the effectiveness of the muzzle device, a decrease in recoil and a decrease in toss when fired.
