One can easily follow the progress made by any kind of innovation by going back in history and noting the various successes achieved along the way. Would you know, the first muzzle brake appeared in 1842 in France and was built by Colonel de Beaulieu. A crude affair, as it consisted of a series of holes in the muzzle region of the barrel. The holes were sloped rearwards to divert the expanding gasses in that direction.
Twenty-one years later, the French military conducted tests with a 106mm gun with 36 holes of 60 mm diameter inclined rearward at 45°. A reputable resource disclosed significant success due to doubling the accuracy and the recoil distance being reduced to only 25 percent while there was only a 6 percent loss in muzzle velocity.
The first attempt where the effectiveness of a brake was tested was soon followed by inventions of Hawley (1871), de Place (1885), Maxim (1890), Simpson (1902), Smith (1903), Sig Sauer (1987). During the latter years, several agencies began to devote efforts toward muzzle brake development, thus lending encouragement to the individuals interested in this field.
It was during the first world war that muzzle brakes of various sorts appeared. Needless to say, it inspired newcomers to experiment, build and test all kinds of hardware.
Muzzle Brakes Today
A muzzle brake is a device that is attached to or is integral with, the muzzle of a gun. Usually, the brake has a series of baffles either at an angle of 90 degrees or as close to the axle of the gun tube as possible. The brake is normally closed off towards the bottom part to keep gasses from breaking free and endanger or annoy the gun crew. To maintain evenly shaped external loading and therefore balance, the top also is closed, leaving the sides open for the gasses to escape after impinging on the baffles. Some standard configurations, adhering to either theoretical or empirical practice, have evolved through years of application.
Immediately as the projectile clears the muzzle, the propellant gasses follow, no longer restrained by tube wall or projectile, but still having a considerable pressure and a velocity equal to or slightly exceeding that of the projectile. If left alone, the gasses expand into air and reduce to atmospheric pressure
However, if the gun has a muzzle brake, a different sequence of 1-2 AMCP 706-251 events ensues. The projectile while passing through the brake continues to restrain, to some extent, the gas flow in the axial direction. However, the ports on the sides of the muzzle brake offer very little resistance to the expanding gas that will flow between the baffles. The general direction of flow is therefore changed. The resultant direction of this gas flow is no longer diagonally forward but is radial or rearward
By diverting the flow in these directions, the gas must impinge on the baffles and induce a forward thrust. This thrust generates an impulse which is opposite in direction to the recoil momentum, thereby reducing that energy by the amount of the muzzle brake impulse. Unfortunately, the brake does not perform while the projectile is still in the bore. The recoiling parts almost reach their full momentum during this time.
Known Advantages Experienced by Users of Top Quality Muzzle Brakes
The primary benefit of a muzzle brake is its ability to decrease the momentum of the recoiling parts of a gun. How this advantage is exploited depends on the weapon assignment.
The main disadvantage of a 308 muzzle brake review is the detrimental effect that the muzzle blast has on the crew, particularly excessive overpressure. Any disturbances of air due to Air disturbances or forward moving gas, loud noise, and heat can be disconcerting
When asked, several hunters, those involved in competition, and other rifle users said they found the advantages of muzzle brakes far outweigh any disadvantages.
No doubt, small arms have achieved notable success thanks to the use of muzzle brakes. Besides, a high degree of effectiveness is typically accompanied by strong muzzle blasts which always suggests a compromise in design. However, improvements are continuing all the time. Take for instance what Madhouse Design came up with recently with their release of the Triple-port Muzzle Brake.
