Just received the email from CHPWS regarding a new product. The PMM Independent Drop-In Rear sight for Trijicon RMR.
An excellent concept that integrates the rear BUIS into the housing of the RMR. Unsure if compatible with RMRCC. It also does not list technical specs such as dimensions or required front sight heights. I really like the idea. Especially for a slide that is being directly milled. Eliminates the need completely for a rear BUIS dovetail and would allow the sight to sit as far back as possible. If compatible with the RMRCC, I may be purchasing this combo and having a Glock 48 slide set up with it.
