The ChamberSafe® blocks the chamber, yet permits fast removal for immediate loading and action.

The ChamberSafe® design allows the rifle or carbine to be carried with a magazine inserted, chamber unloaded, and be visually identifiable as a firearm with an unloaded chamber.

The ChamberSafe® while designed for the AR-15/M-16 system can be employed in many types of semi and full auto rifles and carbines.
