Abstract: A weapon stowage and mounting system for a military vehicle, wherein the weapon stowage and mounting system secures a weapon such as an M16 or M249 emplaced therein and retains such weapon from flying about as a secondary projectile in the event of a vehicle roll over, vehicle collision or vehicle blast event, The weapon stowage and mounting system allows for stowage of a weapon with loaded ammunition magazines, grenade launchers, forward hand grips, and/or rails and scopes still attached to the weapon, thus allowing maintenance of constant mission readiness. The weapon stowage and mounting system also includes a panel of UMWPE material that is positioned in line with the muzzle of a stowed weapon to fully capture a bullet in the event of an accidental discharge of the weapon.
