Kensight M14 Brookfield Picatinny Rifle Rail Mount Black. 4140 chrome-moly steel. Mil-Spec Manganese phosphate finish. The US Tactical System "Brookfield" Scope Mount provides a secure stable scope base that won't shift between shots. Rock-solid three-point mounting system attaches to the factory scope mount screw hole in the receiver and the charger guide dovetail while the setscrew at the front uses the receiver ring as a stop to prevent forward movement. This enhances the stability and eliminates any rocking motion under heavy recoil. No drilling or tapping required to install. This US Tactical Systems M14 Mount is constructed out of a solid billet of 4140 steel. The Wire-EDM manufacturing process leaves the finished product completely devoid of stress. Competing designs lacking in this essential process often result in critical systems failures due to the heavy recoil of the larger caliber rounds. Wire-EDM manufacturing also allows for the tightest tolerances and perfect fit on your Classic M14 rifle.
