An explosive booster is a sensitive explosive charge that acts as a bridge between a (relatively weak) conventional detonator and a low-sensitivity (but typically high-energy) explosive such as TNT. By itself, the initiating detonator would not deliver sufficient energy to set off the low-sensitivity charge.

In spite of its name, a muzzle booster does not increase muzzle force or velocity but instead is usually used to improve the reliability and/or rate ...
[32] [42] Prior to the procurement of the Minimi, the Stabilimento Militare Armi Leggere (SMAL) at Terni has developed a kit to adapt the Italian Army's existing MG-42/59 machine guns to accommodate 5.56×45mm NATO ammunition. The kit comprises a new barrel, bolt head, feed opening and cover, recoil-enhancing element and a lighter bolt.
The concept of a muzzle brake had been experimented with for many years prior to its successful implementation: in 1922, a US Army Ordnance Department official stated in US Congress that "the muzzle brake was used in another form 20 years ago, and even longer ago than that, but it has never been successfully applied".
Another early-WWI improvement introduced in 1915 was a muzzle booster, a patent-protected Vickers invention, which was designated Rückstoßverstärker 08 S. Thanks to that MG 08 came up to its British and Russian analogs with their Vickers-licensed recoil boosters in its rate of fire (up from about 300-350 to 450–600 rds/min) and reliability.
