The Trijicon RMR Mount AC32058 is the purpose-built steel mounting solution that replaces the rear sight on 1911 pistols with a Novak .248 cut to allow direct mounting of any Trijicon RMR - the clean, integrated 1911 Optic Mount solution that gives serious 1911 platform owners the red dot capability that modern competition, duty, and defensive carry shooting demands without any slide milling, additional machining, or permanent modification beyond the existing Novak dovetail cut already present in the slide. The Optic Plate Trijicon AC32058 is specifically dimensioned for the Novak .248 dovetail cut - the industry-standard rear sight dovetail that most quality production and custom 1911 pistols feature from the factory. For 1911 owners whose slide already has the Novak .248 rear sight dovetail cut, the AC32058 installation is a straightforward rear sight replacement that requires no additional slide work to mount a Trijicon RMR in a clean, integrated position. The pistol scope mount AC32058 steel construction reflects the durability requirement that serious 1911 duty, competition, and defensive carry mounting hardware specifically demands - the material strength that handles the sustained recoil cycles that serious 1911 training and competition use accumulates while maintaining the dimensional stability and zero retention that a primary carry pistol red dot mount requires. At 52.6 grams, the AC32058 keeps the overall weight addition practical while delivering the structural integrity that steel construction provides over aluminum alternatives. The Trijicon 1911 Novak Cut .248 RMR Pistol Mount AC32058 accepts any Trijicon RMR configuration, giving 1911 owners the flexibility to choose the specific dot size and illumination type that best fit their shooting application.
