  • Differential recoil diffuser
    Patent number: 4949491
    Abstract: A recoil diffuser (10) includes a plurality of weight elements (20, 22) and a plurality of plastic spring elements (30, 32, 40) fitted within a tube (12) to operate differentially upon being subjected to the forces of recoil as in a shotgun or the like. The end surfaces of the weight elements and of the plastic spring elements (see 24, 28) are shaped to optimize spring forces relative to displacement relative to overall size of the unit and mass of the weights.
