This is our dream for many years. Until the end of 2019, The buckle was successfully used in our Thor Grenade Launcher. Today, the AR-15 type blasters can also be benefited in this convenient design. In the past, to carry such blasters, you could only a sling or gun straps. With these Speed Draw Buckles this solves this problem. Just attach the Speed Draw Buckle to the take down pin on the blaster and you can buckle it to your waist or tactical back (Molle Vest), it is convenient to carry and pull the blaster quickly!
