Why Choose an RMR Cut Slide?
Adding a red dot optic is one of the most effective ways to increase speed and accuracy. A properly machined RMR cut provides a secure mounting platform — no adapter plates, no extra height, no guesswork. Whether you're using a Trijicon RMR or Holosun 507C, this slide keeps your optic low, solid, and ready for action.
You also maintain your factory sight picture by co-witnessing with suppressor-height iron sights, offering fast target acquisition even if your optic fails.
