ABSTRACT:
A recoil dampening device incorporating a dynamic braking system and index ring. The recoil dampening device of the present invention is intended for use on weapons, especially heavy caliber weapons, having a recoiling barrel. The recoil dampening device is coaxial with the weapon's barrel and has a constant pressure brake assembly and a dynamic brake assembly. The recoiling barrel and the brake assemblies are carried within a cylindrical tube that is coaxial with the brake assemblies and the barrel. As the weapon is discharged, the force of the recoil causes the barrel to travel rearwardly thus engaging a coaxial spring. The spring engages the dynamic brake assembly and as the barrel travels rearwardly, the force applied to the dynamic brake is increased in a linear fashion, causing an increasing amount of frictional braking pressure to be applied to the inner surface of the tube and the exterior surface of the barrel. When the frictional braking force exceeds the recoil force, the rearward travel of the recoiling barrel is halted and the energy stored within the spring returns the barrel to battery. Thus the acceleration of the recoil impulse is applied to the shooter through the frame of the weapon over a longer period of time thus reducing the perceived recoil force experienced by the shooter.
