  • Device for firing a projectile
    Patent number: 5515767
    Abstract: A device for firing a projectile for de-arming purposes, comprises a barrel for housing a projectile and an explosive charge. A sleeve surrounds the barrel, so as to define an annular chamber accommodating solid or liquid recoil absorbing material. Radial ports interconnect the barrel and the annular chamber so that when the projectile is fired the annular chamber is pressurized and the recoil absorbing material is expelled rearwardly from the chamber, so as to counteract recoil.
