Adapt Your Sig P320 to the Popular RMR Footprint
The C&H Precision Optic Adapter Plate is a premium mounting solution designed to integrate the popular RMR footprint with the Sig P320 X5 and M17/18 platforms. Engineered for durability and precision, this adapter plate ensures a rock-solid fit, enabling you to enhance your firearm’s accuracy and speed in any shooting scenario.
Designed for Holosun EPS Footprint
This adapter plate converts the Sig Romeo 1 Pro footprint on your slide to securely mount the Trijicon RMR/SRO, Holosun 407C/507C, Holosun 507 COMP, and many more red dots using the RMR Footprint. Please check if your P320 has the Romeo 1 PRO footprint as opposed to the older Romeo 1 footprint. Additionally, make sure your P320 has a Plate Intergrated Rear Sight. This plate comes with a dovetail for a Glock rear sight since users with these pistols would normally lose their rear sight when installing an optic.
Precision Machined
Machined from 6061 aluminum for long-lasting durability, ensuring a solid and stable fit for your optic under heavy recoil and rigorous use. Every C&H Optic Plate is designed, manufactured, and machined in the United States at a small family owned business. Each plate is precision machined to the tightest tolerances on HAAS CNC machines and each plate goes through multiple quality checks before shipping to customers.
Low-Profile Design
Maintaining a thin and unobtrusive profile keeps your firearm looking good and doesn’t raise your optic absurdly high.
Easy Installation
Includes all necessary hardware for a quick, hassle-free setup, allowing you to install the adapter and confidently mount your optic.
