Cole-TAC Backbone Frame Arca Square Bag Frame

The Cole-TAC Backbone Frame is a rigid metal shooting bag frame that mounts directly to your rifle, turning a compatible Cole-TAC support bag into a stable, rifle-mounted rest. Designed around an Arca Square interface, the frame attaches to either an American Defense Picatinny base or an Area 419 Arcalock mount, eliminating the need for straps that wrap over the rifle or optic.

Built from metal with a hard-coat anodized finish for lasting durability in the field, the Backbone Frame pairs with Cole-TAC's Cuddle Bag, Flat Bag, and other shooting bags via its integrated hook-and-loop attachment system. Made in the USA, this frame gives prone and positional shooters a rock-solid, adjustable shooting platform that moves with the rifle instead of sitting loose on the ground.
