Hogue's revolutionary O.M. series stocks are made similar to their popular rubber grips. Constructed by molding a super strong, rigid fiberglass reinforced stock that precisely fits the rifle action. This small "stock" or "skeleton", is then completely OverMolded with the same rubber compound used on Hogue grips. The skeleton or insert, as it is called, chemically as well as mechanically adheres to the rubber resulting in a permanent bond between the rubber and the insert. The super strong insert not only gives the stocks their strength but the precise molded dimensions provide a perfect drop in fit of your rifle action. OverMolding with rubber is superior in every way and provides the ultimate in a comfortable, non slip, super smooth attractive finish, that is durable and extremely quiet.
