CJ Weapons has developed a 21~(st) century bore guide for use in the .308 caliber semi- and full-automatic AR styled rifles. The innovative product is designed to protect a gun's chamber and muzzle. The AR-308 Bore Stay is approximately ten inches long and is made from a solid piece of CNC plastic. The AR-308 Bore Stay locks in place and does not slip during firearm cleaning. The AR-308 Bore Stay solvent port allows additional solvent to be added to the cleaning brush, allowing the cleaning brush to remain in the weapon. CJ's 5.56 Bore Stay served as the AR-308's base of design. CJ Weapons updated the product for the new design.
