TRUGLO PISTOL RED DOT SIGHT MOUNT: Adaptor Provides No-Modification Installation on Popular Handgun Platforms. Installing an optic on a semi-auto handgun used to require sending the slide out to be machined to accept the optic - a costly operation that permanently altered the handgun slide. Now there is a better way, thanks to the new Pistol Red-Dot Sight Mount from TRUGLO. The Pistol Red-Dot Sight Mount takes advantage of the dovetail slot to add an optic mounting base. The mount is made from CNC-machined billet steel, with lightening cuts to reduce weight. Using billet steel allows the mounting plate to be thinner and lower than other aluminum designs while maintaining or exceeding the same strength. The amount is treated with a nitride FORTRESS-FINISH to resist corrosion and match the finish of popular pistol slides. MAIN FEATURES: - Transforms the rear sight dovetail into an optic mount; - CNC-machined billet steel; - Low profile fit; - Easy to install with basic tools; - Nitride FORTRESS FINISH; - Product made in USA; - Available with various gun and optic compatibility options.
