Cole-TAC Backbone Bag Frame BF1001 with ARCA Mount

The Cole-TAC Backbone Bag Frame (BF1001) is a patented rifle support bag frame designed to eliminate traditional straps that attach over the rifle or optic. The hard-coat anodized metal frame attaches directly to the rifle via an Area 419 Arcalock mount (this variant), providing a stable, low-profile platform. Four hook-and-loop straps secure the support bag in place, while the wide frame surface prevents twisting and shifting during use. Compatible with standard rear support bags.
