Glock MOS Adapter Plate Set #03 - Optics Mounting System 9mm

The Glock MOS Adapter Plate Set #03 transforms standard Glock pistols into optics-ready platforms, eliminating the need for expensive slide modifications. This precision-engineered mounting system provides a secure foundation for popular red dot sights while maintaining the pistol's original reliability and accuracy.

What Makes This Different

Unlike aftermarket slide cuts that permanently alter the firearm, this adapter plate system preserves the pistol's factory warranty and resale value. The hardened steel construction distributes optic weight evenly across the slide, preventing stress fractures common with inferior mounting solutions. Each plate undergoes rigorous testing to ensure zero shift under recoil forces exceeding 15,000 rounds.
