Abstract:
A device for preventing the accidental discharge of a bullet from a firearm, suitable for use with blank cartridges, said device comprising:attachment means adapted to fixedly engage the muzzle end of a firearm barrel;a substantially tubular body having a cavity and coaxially attachable at one of its ends to said barrel via said attachment means;a bullet-pierceable insert having a portion traversing said tubular body and also the axis of said barrel when the tubular body is attached to said barrel;said insert being made of a non-combustible material, for trapping gases exiting from said barrel when blank cartridges are fired, thereby causing re-cocking of the firearm;an impact disk slidably disposed in the cavity of said tubular body, andenergy-absorbing and storing means interposed in said tubular body between said impact disk and an abutting means, acting on said impact disk to maintain contact with said insert inside said body,wherein, upon the discharge of a bullet, said bullet pierces said insert and hits said impact disk, transferring some of its kinetic energy to said energy-absorbing and storing means, and is thereby prevented from being discharged from said firearm.
