After over a year of design, development and testing, the strongest light-weight polymer stock available for your mil-spec receiver extension is here! This stock features a snag free Design. There are no sharp edges, which prevents tangling of the rifle with the shooter's sling, molle gear, or other kit. A Modular VBOST (Vehicle Borne Operations Sling Tab) interfaces with the shooter's riggers' band or bungee to secure the shooter's sling against the stock when the carbine is not in use. Increasingly, this is the most common application when operating inside a vehicle. Two different types of ambidextrous sling mounting options, including QD swivel sockets.
