The CHP Weather-Defender Optics Adapter for RMR/SRO/HOLO is a precision mounting solution designed to co-witness modern compact red dots on pistols and handguns that use standard optic-cut slides. Built by C&H Precision Weapons, a family-owned shop in Coastal Georgia, this aluminum adapter plate enables you to run one of the most popular compact optics—Trijicon RMR, SRO, or Holosun 507C, 407C, 508C, and 508T—on platforms configured for those mounting patterns. Whether you're building a duty gun, competition rig, or personal-defense pistol, a quality adapter plate is the foundation of a reliable optic installation.

Each Weather-Defender plate is precision machined on HAAS CNC equipment to tight tolerances and inspected multiple times before it ships to ensure zero shift under recoil and repeatable zero across cleaning cycles. The 6061 aluminum construction strikes a balance between light weight and structural rigidity—you get a rock-solid platform without unnecessary bulk. Stainless steel hardware resists corrosion and stands up to repeated disassembly for cleaning or optic swaps, a detail that matters if you run your gun hard or in wet, salty environments.

Installation is straightforward if you're comfortable with slide work, but remember that mounting an optic on a pistol requires precise fitment to your specific slide and optic combination. CHP makes this adapter for certain platforms and optic pairs—verify compatibility with your exact gun and red dot before ordering. Once locked down, the plate provides a repeatable mounting interface that lets you trust your zero in the field or on the range.
