Muzzle boosters are usually used to improve the reliability of a recoil operated firearm.

A muzzle booster was also added.

The chrome-lined muzzle booster also burns any remaining propellant thus reducing the gun's signature.

The MG42 is roller-locked and Recoil operation (short recoil) with Muzzle booster.

The World War II-era German MG42 was another such machine gun which also made use of a muzzle booster.

The muzzle booster is the antithesis of the muzzle brake, which is designed to use the propellant gases to reduce the recoil of the firearm.

This energy can also be harnessed by a muzzle brake to reduce the recoil of the firearm, or by a muzzle booster to provide energy to operate the action.

The M2 heavy machine gun, while it does not use a muzzle booster normally, can use a similar muzzle booster derived BFA.

The muzzle booster increased the recoil transmitted to the barrel by directing some of the escaping gas into pushing the barrel back rather than letting it all expand outwards at the muzzle.

The reason was not only that Aimo Lahti was ordered to develop the weapon with a new metallic ammunition belt but also because of other improvements, such as accelerator mechanism and muzzle booster.

A new gas block was installed at the muzzle end of the barrel with a new conical flash hider combined with a cylindrical muzzle booster, which features an internal expansion chamber that increases the weapon's reliability.

The launcher fires 40x53mm high velocity, medium trajectory calibre grenades at a rate of 425 rounds per minute, which may be reduced to 360 rounds per minute (by changing the muzzle booster cup position) in order to conserve ammunition.

A muzzle booster or recoil booster is a device affixed to the muzzle of a firearm, intended to harness the energy of the escaping propellant to augment the force of recoil on portions of the firearm.

These designs use a muzzle booster to add energy to the recoiling parts, and muzzle brakes for these designs simply replace the muzzle booster with one that provides far more boost with blank cartridges.

The M1919A6 had a metal buttstock assembly that clamped to the backplate of the gun, and a front barrel bearing that incorporated both a muzzle booster and a bipod similar to that used on the M1918 Browning Automatic Rifle (BAR).
