With an RMR footprint, these Holosun optics are ready to mount onto a variety of mounting systems. The Holosun RMR, or ruggedized miniature reflex, optics lineup features multiple pistol red dot sights that match the footprint of the Trijicon RMR and have an adjustable LED. 

Many of these optics can be directly mounted to RMR optics ready pistols or with the assistance of RMR adapter plates. Find the perfect reflex sight optic for improved target acquisition with our selection from Freedom Gorilla.

Direct Mount vs. Adapter Plate RMR Footprint Compatibility

Direct mount RMR footprint models will directly mount to pistols with the RMR footprint. These include the 407C, 507C, 508T, and 507 COMP series. 

The EPS Full Size uses a modified RMSc footprint, or K Series footprint, which can directly mount to pistols with a K Series or modified RMSc footprint but also comes with an RMR adapter plate for mounting.

The Holosun 509T series uses a 509 footprint and also includes a RMR adapter plate for mounting onto RMR footprint pistols. 22 of the 22 products on our Holosun RMR footprint list can fit full size and compact pistols. 

What's Included with Adapter Plate Models

Both the EPS Full Size and 509T models come with an RMR adapter plate and everything you need for properly mounting to a pistol with an RMR footprint.

Open Reflex vs. Enclosed Emitter Red Dot Options

These Holosun RMR Footprint Optics come as either an open reflex or enclosed emitter. The open reflex optics are open while the enclosed emitters are completely encased, protecting the optic from dust, sand, etc. 

The open reflex optics include: Holosun 507C X2 (Green or Red), Holosun 507C X2 ACSS Vulcan (Green or Red), Holosun 507 Comp CRS (Green or Red), Holosun 407C X2 (Green or Red), Holosun 508T X2, and Ronin Holosun 507 Comp RD MRS

The enclosed emitters include: Holosun EPS Full Size MRS (Green or Red), Holosun 509T X2 (Green or Red), Holosun EPS Full Size 2 MOA (Green or Red), Holosun EPS Full Size 6 MOA (Green or Red), Holosun 509 ACSS Vulcan, Holosun 509T X2 FDE Green Dot, and Holosun 509T FDE. 

The housing material of 15 of the RMR footprint optics models is the durable 7075-T6 aluminum while the remaining 6 models, the Holosun 509T and 508T, use Grade 5 titanium for the housing. 

Our selection is also balanced between green and red dot reticles with 10 green dot reticle models and 11 red dot reticle model 

Multi-Reticle System (MRS) Technology

We have 10 models available with MRS, or Multi-Reticle System Technology. This technology allows you to toggle between the reticle options of a 2 MOA Dot, 32 MOA Circle, or both at the same time, allowing for rapid target acquisition benefits. 

ACSS Vulcan 10 MOA Chevron Reticle

The Holosun 507C X2 ACSS Vulcan (Green and Red) and the Holosun 509 ACSS Vulcan are the three ACSS Vulcan models we have available. These astigmatism-friendly RMR footprint optics use a 10 MOA Chevron Reticle that acts like a BDC, or bullet drop compensator.

Solar Failsafe & Shake Awake™ Technology Features

Out of the 22 models of our Holosun RMR footprint optics, 15 have an additional solar failsafe: solar panel at the top of the optic that powers the unit by sunlight or ambient light. These units also have side removable batteries. The other 6 models that don’t have a solar failsafe have a removable battery that can be replaced. 

All Holosun RMR footprint optics come with Holosun’s Shake Awake™ technology. This technology automatically turns the optic off after a period of inactivity and reactivates when it senses motion. 

Models with a side access removable battery can have their battery replaced even when mounted to a pistol.

Competition Ready CRS Reticle System

The Competition Ready Reticle System (CRS) is available on the Holosun 507 Comp CRS with a green or red dot. This makes you competition ready with a 8/20/32 MOA circle and 2 MOA dot, giving you multiple reticle options.
