The Reptilia Dot Mount 1.93" RMR is a precision mount designed for shooters running red dot optics on AR-pattern rifles and other firearms with M1913 Picatinny rails. This slim-line mount positions your optic at 1.93 inches above the rail—a height that clears most co-witness setups and provides natural sight picture for shooters accustomed to traditional rifle ergonomics. Built from billet 7075-T6 aluminum with a durable Milspec Type III hard anodized finish in FDE (Flat Dark Earth), it handles the recoil and environmental demands of hunting, duty, and tactical shooting without unnecessary bulk.

Installation is straightforward: the spring-loaded nitrided steel clamp and fastening system sit flush with the mount body, eliminating snag points and maintaining a low-profile footprint on your rail. Reptilia's design philosophy emphasizes simplicity and reliability—no levers, no rotating components, just a solid mechanical interface that holds zero and stays put. The FDE finish blends seamlessly with modern rifle platforms and pairs well with contemporary optic aesthetics.

This mount works with a range of red dot platforms that share RMR mounting geometry, making it a versatile choice whether you're pairing it with a Trijicon RMR, an Holosun HS407K, or compatible variants. If you're building a lightweight hunting rifle, upgrading a duty gun, or setting up a precision 3-gun platform, the 1.93" height offers flexibility without compromising sight radius or ergonomics.

Frequently Asked Questions

What red dot optics does this mount fit?

The Reptilia Dot Mount 1.93" RMR is compatible with Trijicon RMR and Holosun HS407, HE407, HS507, HE507, and HE508 series optics—any red dot that uses RMR mounting geometry.

Will this mount fit my AR-15 or other Picatinny rail system?

Yes. This mount attaches to any M1913 Picatinny rail found on AR-pattern rifles, shotguns, bolt rifles, and other firearms with standard top rails.

What does the 1.93" height mean, and why does it matter?

The 1.93" measurement is the distance from the Picatinny rail to the optical axis of your red dot. This height places the optic above most co-witness and backup iron sight configurations, giving you a clean sight picture while maintaining tactical flexibility if you want to run irons alongside your dot.

How difficult is the installation?

Installation is simple. The spring-loaded clamp and mounting bolt secure your optic to the mount, which then locks onto your Picatinny rail. All components sit flush with the body for a streamlined profile.
