The Spuhr Trijicon RMR Red Dot Mount Interface is a precision-machined accessory designed to attach a micro red dot directly to a Spuhr Ideal Scope Mount System (ISMS). Crafted from lightweight, high-strength T651 aluminum, this adapter allows shooters to run a secondary, unmagnified optic at a 12 o'clock or 45-degree offset for fast transitions to close-range targets. While engineered specifically for the Trijicon RMR (Types 1 and 2) and Trijicon SRO, its footprint also natively shares compatibility with popular options like the Holosun HS407C, HS507C, and HS508T. This unit weighs just 0.7 ounces, measures 0.374 inches in height, and comes packaged with a dedicated shim plate and mounting hardware. Note that it is threaded for 6-32 UNC screws and is designed exclusively for ISMS mounts rather than the Spuhr Hunting Series. Spuhr Trijicon RMR Red Dot Mount Interface A-0010i
