The AD-T1 Mount by American Defense Manufacturing is a lightweight and extremely durable option for mounting the Aimpoint T1/T2 (and other optics with the same footprint) onto modern sporting rifles. It features a hard coat Type 3 Mil-Spec anodized finish for superior corrosion and weather resistance, and is precision machined from 6061 T6 aluminum – this construction reduces the weight of the mount by 20% when compared to mounts of a similar class. The AD-T1 Mount was also designed to be sleeker, and provides a less obstructive field of view to promote greater situational awareness. The AD-T1 attaches to the host weapon via ADM’s patented QD Auto Lock Lever system, allowing the mount to accommodate both in spec and out of spec rails, and provides a superior clamping surface and maximum rail engagement. In addition, the AD-T1 is available in in absolute co-witness, lower 1/3 co-witness and High (1.93") heights in Black and Flat Dark Earth finishes. Features of the AD-T1 Mount: The AD-T1 lightweight mount features the Patented QD Auto Lock Lever system. Does not require proprietary tools for adjustment. Can be adjusted with your finger or a flat blade screwdriver. Lever can be configured to lock to the front or the rear. Superior clamping surface to insure maximum rail engagement.
