Trijicon 700816 RMR Dual Defense Cerakote Black/FDE 1x 3.25 MOA Red Dot Reticle Fits Sig Sauer M17/18

The Trijicon RMR Dual Defense red dot sight is a purpose-built optic system for the Sig Sauer M17 and M18 pistols, combining a proven compact red dot with co-witnessed iron sights for duty, self-defense, competition, or range use. This kit pairs the RMR's proven reliability with suppressor-height night sights that align perfectly through the optic, giving you a redundant aiming solution if your dot fails or you need to transition to irons fast. The Cerakote Black/FDE finish is durable and professional, blending function with a clean aesthetic on modern duty or carry pistols.

Built for serious shooters who demand speed and precision, the RMR Dual Defense system eliminates the guesswork of aftermarket sight selection. The included night sights are engineered to proper optics-height geometry so iron sight posts remain visible within the lens, letting you confirm your dot picture and transition instantly if needed. Whether you're training for competition, building a duty gun, or setting up a personal-defense pistol, this kit removes the burden of sourcing compatible components separately.

Trijicon's RMR technology is combat-proven and trusted by military and law enforcement worldwide. The optic automatically adjusts its brightness to ambient light, so your reticle stays visible in direct sun or low-light scenarios without manual tweaking. Waterproof construction and 1 MOA windage/elevation adjustments allow you to dial in precision at your preferred range, while the 3.25 MOA red dot reticle is large enough for rapid target acquisition without sacrificing accuracy. For shooters serious about M17/M18 performance, the Dual Defense kit delivers both speed and failsafe backup in one integrated package.

Frequently Asked Questions

Will the iron sights be visible when looking through the RMR?

Yes. The included suppressor-height night sights are engineered to the correct height so the sight posts remain visible within the RMR lens, allowing you to see both your red dot and your iron sights simultaneously for fast target acquisition or backup aiming.

Is this compatible with my Sig Sauer M17 or M18?

Yes, this Dual Defense kit is specifically designed for the Sig Sauer M17 and M18 platforms and includes everything needed for that fit.

What if the red dot fails—can I still aim?

Absolutely. The co-witnessed iron sights function as a reliable backup, letting you transition to iron sights immediately if the optic is damaged or the battery fails.

How does the brightness adjustment work?

The RMR automatically adjusts the aiming dot's brightness to match ambient lighting conditions, so your reticle remains visible in bright sunlight and low-light shooting without requiring manual adjustment.
