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.

A rifle includes a magazine well, a barrel, and an exo-bolt. The barrel is configured to be detachably coupled to the magazine well. The barrel includes a forward barrel portion on an end of the barrel opposite the magazine well. The exo-bolt is configured to travel along an exterior of the barrel.

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.

A disrupter includes a barrel through which a projectile is fired, a barrel housing, at least one spring to absorb recoil energy, a frame and a stand on which the frame is supported. The barrel housing includes a sleeve to receive the barrel and allow movement of the barrel therethrough. The barrel may be selectively pivoted on the frame.

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 rifle includes a magazine well, a barrel detachably coupled to the magazine well, and a suppressor detachably coupled to the barrel. The barrel includes a forward barrel portion on an end of the barrel opposite the magazine well. The forward barrel portion includes a muzzle locking mechanism. The suppressor is configured to be retractable.
