Abstract : A dual rate of fire mechanism in an automatic weapon absorbs and dissipates a portion of the recoil energy to produce a slow firing rate and inactivates the energy absorbing elements to produce a rapid firing rate. Compression of a recoil spring stores the recoil energy of the weapon bolt and normally returns substantially all of the energy to the bolt in a counter recoil portion of the cycle. In slow firing mode, some of the energy stored in the recoil spring is dissipated in a positioning spring thus providing less energy to the counter recoil action and slowing the rate at which succeeding rounds are fired.
