A compensator for a firearm includes a body defining a projectile opening therethrough along a longitudinal axis, where the projectile opening is sized for passage of a projectile fired from the firearm. The compensator includes a removable partition than can be separated from the rest of the compensator to aid in cleaning and servicing. The partition can be replaced without needing to replace the entire compensator.

A muzzle brake having a tuner and allowing for micro-adjustments to the weight of the barrel of a firearm. Upon being fired, the weighted the barrel mitigates the effect on aiming by disruptive frequencies reverberating through the firearm. The muzzle brake can incorporate a muzzle brake and be positioned after the muzzle brake segment such that the harmonics of the muzzle brake segment can also be affected by the muzzle brake. Use of the tuner on a firearm can increase overall accuracy and affect the groupings of shots on target when compared to use of a firearm without a muzzle brake.

A tunable muzzle compensator for a weapon such as a firearm that includes a tube that extends the barrel of the weapon by fitting over the muzzle or is directly integrated into the barrel. This center tube, or modified barrel includes one or more holes along its length. One or more removable sections that have gas exit ports at various predetermined angles fit over the center section. Removable sections can be rotated to either turn off top holes on the center tube or to choose different angles of gas discharge The total effect of all the removable sections represents a particular tuning for the weapon. The weapon can be very quickly tuned on the range or in the field to compensate for weight of the projectile, the charge, and the shooting style by simply replacing and/or reversing removable sections with sections that have different angles of discharge.

A firearm compensator assembly includes a compensator base that may be mounted to a barrel of a firearm, the base having a contact surface. A cylindrical-shaped compensator body has a bore, an axis, a sidewall, a contact surface, an outer surface and at least one gas discharge port extending through the sidewall between the bore and the outer surface. A spring exerts a biasing force urging the body contact surface into engagement with the base contact surface whereby the body is locked to the base. The gas discharge port is rotatable around the axis by urging the body contact surface away from the base contact surface against the biasing force of the spring.
