Geissele Spr Prcsn T1 1/3 Co-wit B

The Geissele Super Precision T1 1/3 Co-witness Black mount is a precision-engineered optic mount designed specifically for Aimpoint T1 and similarly mounted red dot systems. Machined from a single billet of 7075-T6 high-strength aluminum, this mount delivers the rigidity and repeatability operators demand when zeroing mission-critical equipment. The 1400-pound clamping force and three integral shear lugs ensure your sight stays locked to zero through sustained fire, tactical transitions, and field deployment.

Geissele's refined nut-and-bolt clamping system updates the classic mounting method to eliminate creep and drift over time. The 1/3 co-witness height positions the red dot sight at one-third the height above the receiver rail, aligning the reticle with iron sights for rapid transition between optical and mechanical aiming references. This configuration is standard for modern tactical rifles where maintaining iron sight capability provides a backup aiming system without sacrificing co-axis velocity or sight picture.

This mount serves patrol rifles, precision platforms, and duty carbines where users demand repeatable, zero-loss installation. Its compact profile—4.25 inches in length and weighing just 0.25 pounds—adds minimal bulk while maximizing operational flexibility. Whether integrating with MIL-STD-1913 rail systems on AR platforms, shotguns, or bolt-action precision rifles, the Geissele Super Precision T1 provides the clamping security and optical stability that separates field-proven equipment from commercial alternatives.
