The Badger Bone is a simplistic, purpose designed sand sock and was the the result of input from over a dozen Military Snipers, Police Marksman and Competition Shooters. The Bone can be used in several different configurations and has an integrated filler neck so the Bones volume can be tailored to the individual shooters needs. Badger Bones come filled with stable non-absorbent material for years of service. Weight: approx: 7.8 oz
