Crosstac Lockout Sling HK Connectors Coyote Brown. The bungee is activated by releasing the buckle which is easily unclipped and reclipped with the off hand. Reclip it single handed so the rifle doesnt bounce around unclip it instantly as needed. The limited travel design (same as our other slings) gives you enough movement without being overly stretchy.
