The Graco BreaKO end cap weight (also called a counter weight) is very easy to install. Simply unscrew the factory cap at the forward end of the magazine and screw on the new end cap weight to add weight to the front of the shotgun. Adding weight to the front end of the shotgun produces a smoother swing for better follow through on the target and reduces muzzle jump and recoil by putting weight where it has the greatest effect. Theses end cap weights are precision machined from a solid billet of steel. Fits 12ga Beretta 391 series shotguns only.
This model weighs 9.5 ounces and has a polished blue finish
