Cole-Tac Trap Bag with Arca Backbone

Paid 98 USD for backbone and 67 USD for Bag.  Comes filled with polymer beads.  Note:  This is not a waxed bag.

Trap Bag can be used over a wide range of objects and surfaces, creating endless possibilities. Whether you need to rest the bag on a barricade or use it as a rear bag, the Waxed Trap Bag forms over the object to make a flat, smooth surface. Our engineers designed the Waxed Trap Bag to fold over objects while still providing a stable surface to balance your rifle.

The Backbone Bag Frame represents the next revolution in support bags. The patented design eliminates the need for straps that attach the support bag over the rifle or optic. The hard-coat anodized frame attaches to the rifle by either an American Defense Picatinny mount or an Area 419 Arcalock mount. Four Hook and Loop straps keep the bags securely in place, and the wide surface area of the frame prevents the bags from twisting and shifting.
