Coletac BF1003 Backbone Frame with Arca Square
Revolutionary support bag frame with hard-coat anodized construction. Attaches via Picatinny or Arca mount. Four hook-and-loop straps secure bags without rifle interference.
The Backbone Frame: A New Standard in Rifle Support
The Coletac BF1003 Backbone Frame represents a genuine innovation in shooting support equipment. Rather than relying on straps that wrap over your rifle or optic—a design that has remained largely unchanged for decades—this frame takes a different approach entirely.
Key Features
- Patented rigid design eliminates the need for over-the-rifle straps that can interfere with your shooting position
- Dual mounting options: Attaches via either American Defense Picatinny mount or Area 419 Arcalock mount for maximum versatility
- Hard-coat anodized construction provides durability and corrosion resistance in field conditions
- Four hook-and-loop straps secure your support bags firmly in place
- Wide surface area prevents bags from twisting, shifting, or rotating during shooting
Why This Matters
Traditional support bag systems force you to work around straps that cross your rifle. The Backbone Frame mounts directly to your rifle's existing accessory slots, keeping your bags stable and in position without adding bulk or complexity to your setup. The rigid frame design means your bags stay exactly where you position them—critical for precision shooting where consistency is everything.
Whether you're at the range, in the field, or competing, the Backbone Frame delivers the stable platform serious shooters demand.
