A muzzle booster is a device for automatic weapons can increase the charging frequency or change systems increases the reliability of weapons. Recoil amplifiers were already known before the First World War.

technology

The gases escaping during the shot are used to reinforce the recoil in order to increase the recoil force . The aim is to have more energy available for the self-loading mechanism of recoilers . Recoil boosters are only used with recoil loaders.

In the case of an active recoil intensifier, the gas pressure acts in a chamber with the support of which a mechanism causes the recoil intensification. This takes place, for example, with gas extraction near the muzzle of the barrel in a cylinder in which a pipe guide sleeve runs backwards together with the closure .

In the case of a reactive recoil booster, there is a diffuser at the muzzle , a kind of funnel that acts like a nozzle of a recoil drive. The additional recoil force of this device is available for the self-loading process.

Some maneuver cartridge devices act as recoil amplifiers to be able to fire blank cartridges .

  • Maxim machine gun still without a nozzle

  • MG 08/15 with nozzle

  • Browning M2 without recoil booster

  • Browning M2 with reactive recoil booster

Applications

The “ recoil booster S ” was developed for the MG 08/15 machine gun in order to increase the rate of fire from the original 300 rounds per minute with the predecessor model Maxim machine gun to around 450 rounds per minute. For the Swiss Lmg 25 , a nozzle-like "blind shooting device" is known, which could be attached for functional reliability when using practice ammunition . A well-known weapon with an active recoil amplifier is, for example, the MG3 and its predecessors such as the MG 42 . A common weapon with a reactive recoil amplifier is, for example, the Vladimirov KPW super-heavy machine gun .
