Silent Steel - Safe Breaker

Silent Steel Safe-Breaker is a small and handy 3in1 accessory for multiple uses. It can be used to cut concrete enforcement bars. At the muzzle there are four glass breaker spikes to break car windows. It works also as a blast can since it forces the gas pressure forward. The forward forced pressure also directs metal shrapnel forward, away from operator when cutting enforcement bars. The spikes at the muzzle helps to hold barrel at the correct position when shooting/breaking door locks and hinges.

Safe-Breaker can be installed on all Silent Steel muzzle devices. Muzzle device o-ring keeps the Safe-Breaker securely on its place and allows Safe-Breaker to rotate and index into preferred position. After reinforcement bar is placed into Safe-Breaker slot, o-ring locking allows rifle to be rotated to preferred and safe position before shooting.

The heat resistant o-ring peak temperature resistance is 400c degrees. In our test the muzzle device temperature, with AR15 equipped with 5.56 Compact Streamer, was 280c degrees after 6 x 30 rounds magazines in row.
