The Badger Ordnance Badger Bone Sand Sock is a highly versatile, purpose-designed rear shooting rest bag developed using direct design input from over a dozen military snipers, police marksmen, and competitive match shooters. Departing from traditional cylindrical sand socks, its distinct bone-shaped geometry allows for multiple, adaptive height configurations depending on how the shooter positions the bag beneath the rifle stock. It features an ingenious, integrated filler neck that allows shooters to customize or drop the total internal volume to exact field preferences. Wrapped in a rugged, military-grade DCU (Desert Camouflage Uniform) 3-Color Camo fabric, the bag comes pre-filled with a highly stable, non-absorbent pellet material that will not retain water, rot, or degrade over years of deployment.
