Abstract
It has been shown that at high firing rates or cadences, especially in externally powered firing weapons like Gatling guns, the rebound of the breechblock head during its locking at the rear end of the weapon barrel can have damaging effects. At its rear end the weapon barrel possesses an internal circumferential groove following, in a forward direction of the weapon barrel, an annular flange provided with teeth forming an inner gear toothing. The breechblock head possesses teeth forming an outer gear toothing. In the locked position of the breechblock head the teeth of its outer gear toothing are located in the aforementioned internal circumferential groove and bear upon the teeth forming the inner gear toothing of the annular flange. The damaging effects due to the rebound of the breechblock head can be alleviated or completely avoided by widening the circumferential groove.
