Abstract
A recoil brake or block mechanism for an automatic fire arm having a linearly reciprocating breech block. This mechanism includes a slide which is reciprocally mounted on the breech block. A two-armed lever is pivotally mounted in the housing of the fire arm and is adapted to coact with the slide so as to absorb a portion of the recoil energy. The slide has front and rear contacting surfaces and the two-armed lever has a pair of arms, each of which has a control surface which is adapted to respectively coact with one of said contacting surfaces. The center of gravity of the two-armed lever is located in the longer arm of the two-armed lever at a distance from its pivot support.
