Revolutionary hard-anodized support bag frame that mounts directly to Picatinny rails. Eliminates traditional straps with secure Hook and Loop attachment and prevents bag shifting during shooting.
The Coletac BF1002 Backbone Frame represents a genuine advancement in how shooters stabilize their rifles. Rather than relying on straps that wrap over your rifle or optic—a solution that has frustrated marksmen for decades—this frame mounts directly to your Picatinny rail system.
A support bag that moves during your shot is a support bag that doesn't support. The Backbone Frame's rigid connection to your rifle ensures your bags stay exactly where you need them—shot after shot. Whether you're working a precision rifle, running a competition stage, or conducting serious field work, this frame gives you one less variable to manage.
