Cole-Tac BF1003 Backbone Frame ARCA Square

The Backbone Bag Frame represents the next revolution in rifle support bags. This innovative frame eliminates the need for traditional straps that attach support bags over the rifle or optic. The hard-coat anodized aluminum frame attaches directly to the rifle via either an American Defense Picatinny mount or an Area 419 Arcalock mount. Four hook and loop straps securely hold the bags in place, while the frame's wide surface area prevents bags from twisting and shifting during use. Features patented design for superior stability and precision shooting support.
