ABSTRACT:
A fragment-sealing bullet trap for rifle muzzle launched projectiles having a soft aluminum plug for decelerating and absorbing the softer components of rifle bullets, followed by a shock absorbing piston to mitigate the peak acceleration of the projectile due to bullet impact, in turn followed by a hardened steel anvil to safely capture any steel bullet components. Attached to the aft portion of the plug is an aluminum cap, containing a rubber gasket, which expands during bullet penetration, but rebounds due to its resiliency, tightly sealing off the bullet trap against the escape of bullet and plug fragments. The cap is designed to prevent the gasket from blowing out as a result of high bullet trap pressurization.
