The Reptilia RMU Mount is a precision magnifier riser designed to co-witness magnification optics with lower-mounted red dot sights on Picatinny rails. If you're running a 3x or 6x magnifier behind a compact red dot—think a micro reflex sight at 1.93 inches in height—this mount bridges the gap by raising your magnifier 0.39 inches, putting both optics in proper optical alignment. Built from billet 7075-T6 aluminum and finished with Mil-Spec Type III hard anodote, the RMU is a lightweight, durable solution that doesn't add bulk to your rifle.
Reptilia engineered this mount to be low-profile and snag-free. The spring-loaded nitrided steel clamp and recessed bolt sit flush with the body, so nothing catches on your gear during transitions or storage. Installation is straightforward—it mounts to any M1913 Picatinny rail and clamps down securely. At just 51 grams, it won't throw off your rifle's balance, and it's made in the USA.
Whether you're setting up a precision optics stack for flat-range work, hunting, or defensive rifle builds, the RMU Mount solves a real problem: maintaining sight picture and target acquisition when magnification and a primary aiming system need to coexist. The black anodized finish blends with modern rifle platforms and resists corrosion and wear.

Frequently Asked Questions
What magnifiers work with the Reptilia RMU Mount?
The RMU is designed to work with 3x and 6x magnifiers in their original mounts, which typically measure 39mm or 1.54 inches in height. It can also be used with other optical accessories or backup iron sights that need height adjustment.
Will this mount work with my red dot sight setup?
Yes, if your red dot optic sits at approximately 1.93 inches in height (such as Reptilia's DOT Mount for Micros or similar compact reflex sights), the RMU will raise your magnifier into optical co-witness alignment. Always verify your red dot's specific mounting height for best results.
What rail does the RMU Mount attach to?
The RMU mounts to any M1913 Picatinny rail, which is the standard on most modern rifles and upper receivers.
Is installation complicated?
No. The spring-loaded steel clamp and mounting bolt make installation straightforward—simply position the mount on your rail and tighten the bolt. The recessed design keeps everything low-profile and secure.
