Frequently asked questions

Will this plate fit other RMR variants besides the RMRcc?

No. The RMRcc is a smaller footprint optic than the full-size RMR. This plate is cut specifically for RMRcc dimensions. Using other RMR versions will result in improper fitment and safety concerns.

Do I need a gunsmith to install this mount plate?

Professional installation is strongly recommended. The plate must align perfectly with the slide milling to maintain sight reliability and zero stability. Improper installation can compromise accuracy and durability.
