## Abstract

A muzzle brake for weapons includes a body (1) that is joined to the firearm (6) and that incorporates two recesses (1a, 1b) on its surface, where a plurality of holes (1c) are located; and in which on each of the recesses (1a, 1b) a body (2) is located, which incorporates, in turn, a plurality of holes (2a) coinciding in number with the holes (1c) and located in the opposite direction in such a way that there is a reverse of gases coming from the firing of the projectile from the weapon (6).

## Claims

### Claim 1

A muzzle brake for weapons comprising:
a main body adapted to be joined to a firearm, said body including:
a central channel that ends in a central hole, which allows a projectile from the firearm to exit once the projectile has been fired,
two recesses on an outer surface thereof, each recess including a plurality of first holes inclined at approximately 45° in a direction of firing of the projectile;
a second body on each of said recesses, each second body including a plurality of second holes coinciding in number with the first holes in the recesses and inclined in an opposite direction from said first holes in such a way that there is a reverse of gases coming from the firing of the projectile from the weapon;
a series of internal springs that are housed in the main body and cross the main body longitudinally through longitudinal holes in the main body;
guide rods that extend through the longitudinal holes;
a series of baffles; and
tubular bodies that join said main body with said series of baffles which are responsible for redirecting a remainder of the gases that have not been redirected through the first and second holes and for violently pulling the main body that holds said baffles, in the same direction as gas outflow from the firing of the projectile.

### Claim 2 (depends on 1)

The muzzle brake according to claim 1 in which the baffles each have a central hole coinciding in location with an axis created between a barrel of the firearm and the central hole of the main body, and that allows the projectile to exit.

### Claim 3 (depends on 1)

The muzzle brake according to claim 1 where the muzzle brake is embodied in a monoblock body.

### Claim 4 (depends on 1)

The muzzle brake according to claim 1 in which the muzzle brake is embodied in several parts assembled to one another.

### Claim 5 (depends on 2)

The muzzle brake according to claim 2 where the muzzle brake is embodied in a monoblock body.

### Claim 6 (depends on 2)

The muzzle brake according to claim 2 in which the muzzle brake is embodied in several parts assembled to one another.
