Cole-tac Backbone Bag Frame for Picatinny Mount

The Backbone Bag Frame represents the next revolution in support bags. The patented design eliminates the need for straps that attach the support bag over the rifle or optic. The hard-coat anodized frame attaches to the rifle by either an American Defense Picatinny mount or an Area 419 Arcalock mount. Four Hook and Loop straps keep the bags securely in place, and the wide surface area of the frame prevents the bags from twisting and shifting.
