C&H Precision Optic Plate SIG P320 Legion/M17/M18 R1P/DPP Cut to RMR - Steel - SGX-RSH-GDT-ST

Unlock greater optic flexibility for your SIG Sauer P320 Legion, M17, or M18 pistol with the C&H Precision Steel Optic Adapter Plate. This precision-engineered mounting solution converts the factory Romeo1 Pro / DeltaPoint Pro (R1P/DPP) slide cut into a standard Trijicon RMR footprint, allowing you to securely mount popular red dot sights without custom milling.

Key Features

• Robust Steel Construction: Fabricated from durable mild-grade steel for superior strength and long-term reliability under recoil and demanding use.
• Precision CNC Machining: Produced on HAAS CNC equipment to tight tolerances, ensuring a perfect fit and consistent performance.
• MIL-SPEC Finish: Hard anodized black coating provides corrosion resistance and a professional appearance.
• Comprehensive Hardware Kit: Includes stainless steel mounting screws for the plate and multiple optic options, plus compatibility with Glock-style rear sights via integrated dovetail.
• Ultra-Thin Profile: Measures approximately 0.095–0.099 inches thick to minimize height-over-bore while maintaining structural integrity.

Optic Compatibility

This adapter supports the Trijicon RMR and RMR-cc footprints along with compatible models such as the SRO, Holosun 407C, 507C, 507Comp, and 508T. It solves the common pain point of limited optic choices on factory SIG cuts, delivering a rock-solid zero that withstands repeated firing cycles.
