Savage Range Systems —manufacturers of indoor and outdoor shooting ranges, bullet traps, target systems, and shoot houses—has been awarded U.S. Patent Number 7,434,811 for its Air Barrier System (ABS).
The ABS is designed for use with the dry Snail Bullet Trap. A closed loop system uses positive pressure at the throat of the trap to create an air barrier that keeps the lead particles where they belong…inside the patented deceleration chamber.
