Muzzle brake for a firearm

An apparatus comprising:

• an inner shroud configured to permit passage of a bullet and gasses that propel the bullet through a barrel of a firearm through a longitudinal axis and having a plurality of inner vents configured to vent the gases that propel the bullet;
• an outer shroud at least partially disposed around the longitudinal axis of the inner shroud and having an outer surface having a rail portion that functions to continue a rail portion of a system of the firearm for accessory attachment and forming a chamber between the inner shroud and the outer shroud, the outer shroud having a plurality of outer vents configured to further vent the gases that propel the bullet that are received from the plurality of inner vents through the outer shroud and away from the firearm;
• and
• an attachment portion formed as part of the inner shroud, the attachment portion configured to form a removable attachment to the rail system of the firearm using a locking mechanism which includes a protrusion configured to engage and disengage within a receptacle in response to user actuation.

A system comprising:

• a firearm configured to fire a bullet;
• and
• a muzzle brake including;
• an inner shroud forming a first chamber to permit passage of the bullet and gasses that propel the bullet through a barrel of the firearm through a longitudinal axis and having at least one vent configured to vent the gases that propel the bullet, the first chamber formed to permit the barrel and an accessory attached to an end of the barrel to freely float within the first chamber without contacting the inner shroud;
• an outer shroud at least partially disposed around the longitudinal axis of the inner shroud and forming a second chamber between the inner shroud and the outer shroud, the outer shroud having at least one vent configured to further vent the gases that propel the bullet that are received from the inner shroud through the outer shroud;
• and
• an attachment portion attached to at least one of the inner shroud or the outer shroud, the attachment portion configured to form a removable attachment to the firearm such that the barrel of the firearm and the accessory attached to the barrel freely floats with respect to the inner shroud and does not contact the muzzle break.
