The Backbone Bag Frame represents the next revolution in support bags. The patent-pending design eliminates the need for straps that attach the support bag over the rifle or optic. The hardcoat-anodized frame attaches to the rifle by either an American Defense Picatinny mount or an Area 419 Arca lock mount. Four Velcro straps keep the bags securely in place, and the wide surface area of the frame prevents the bags from twisting and shifting.
Will fit 38 mm or 1,5″ Arca rails
Made in USA
