PRI "Gas Buster" Combat Charging Handle Latch. Easy to install on standard charging handle making it a "Gas Buster". I installed it & really liked the way it worked, but all extended latches poke me in the ribs. As new, my cost $19.95 + shipping, yours for $12 Shipped. Gifted paypal, cash or personal check. E-Mail is the best way to reach me.
