Bravo Company introduces the BCM® Stock Assembly - Mod 0 - SOPMOD (Widebody). 
 The strongest light-weight polymer stock available for your mil-spec receiver extension is here!   
 
- More pronounced cheekweld      (SOPMOD type)
- Snag free Design. No sharp      edges prevent tangling of the rifle with the shooter's sling, molle gear,      or other kit.
- Modular VBOST (Vehicle      Borne Operations Sling Tab)   This 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.
- 2 different types of      ambidextrous sling mounting options, including QD swivel sockets.
- Simple modular design. 6      parts, and 1 screw allow for modular adaption of future stock options and      configurations.
