I'd love to hear all about a "velcro" keeper... enlighten us please.
Velcro strapping could be used in various ways.
1. Attach a piece to the top of the pack strap. Attach a mating piece to the rifle strap, either underneath or at the inside edge.
2. Put a loop on the pack strap, attached at the center of the strap. Shoulder the rifle and connect the loop.
No matter the method, attachment and detachment of the rifle should be very quick. Haven't ever tried it with a rifle but have used a lot of Velcro to hold things in place where frequent detachment is required.
