C&H Precision PMM Independent Drop-In Rear Sight (Idrs) For Trijicon RMR BUIS-IDRS-RMR

The C & H Precision PMM Independent Drop-In Rear Sight (IDRS) for Trijicon RMR is a ultra-low-profile, unmagnified 1x back-up iron sight (BUIS) component designed to solve the lack of rear sights on custom-milled or factory optics-ready pistol configurations. Developed by Parker Mountain Machine and distributed through C & H Precision, this specialized rear iron sight completely drops directly into the open drainage or mounting screw section on the rear housing of a Trijicon RMR or RMRcc red dot. CNC-machined from durable 6061-T6 aluminum and treated with a MIL-SPEC black hard-coat anodized finish, this sight provides a highly compact, non-obtrusive lower 1/6 to 1/8 "low-witness" sight alignment across the bottom of the optic window without consuming slide space or a traditional rear dovetail pocket. It serves as a passive structural component requiring zero battery power or electronics to operate. Available online through professional shooting gear storefronts like Arnzen Arms, this independent drop-in sight allows operators to run a reliable physical back-up sighting platform while preserving a clean field of view.
