Abstract
A spring/rod recoil assembly may be improved with Belleville springs arranged in combinations of nested and inverted stacks that absorb recoil impact energy while providing rebound energy to properly load cartridges from the magazine into the chamber. A firearm assembly may include a cylindrical spring, and guide rod—having stops at both ends—lengthwise situated within the cylindrical spring. The assembly may include a Belleville spring stack captured on the guide rod between a back-end stop and the cylindrical spring, with one or more stacks of nested springs and one or more stacks of inverted springs. The spring stack may be arranged to return some of the recoil energy produced during firing of the firearm, and decelerate slide velocities without damage to the firearm. Each spring has a diameter allowing it to fit within a back chamber where at least the back-end of the guide rod and spring are situated.
