Direct-Mount Superiority: Unlike factory MOS systems that rely on 2mm of plate-to-slide engagement, a Legion Precision direct-cut provides 4mm+ of thread engagement directly into the slide.
Bore Axis: Our cuts are machined to the lowest possible depth while maintaining structural integrity, often allowing for a lower 1/3 co-witness with standard-height irons depending on the optic model.
The “Press Fit” Guarantee: We machine to a tolerance of +/-0.001 inches. Your optic shouldn’t just sit on the slide; it should snap into place, using the pocket walls to absorb recoil instead of just the screws.
