The EGW Advantage: A Perfect, Battle-Tested Fit

The Trijicon RMR footprint is the gold standard for pistol-mounted optics, trusted by law enforcement and competitive shooters worldwide. Our Trijicon RMR red dot adapter plates are engineered for a precise, action-specific fit, creating a rock-solid foundation that will not fail. While a universal optic plate might seem versatile, they often lead to a compromised fit. Choose the dedicated mount made for your firearm.

Uncompromising Quality & Premium Materials

Every EGW optic plate is CNC machined from ultra-strong 7075 T6 billet aluminum in our Pennsylvania facility. We choose 7075 aluminum for its superior strength and rigidity, ensuring maximum durability under the harshest recoil. This process guarantees every mount is dimensionally perfect and free from the hidden stresses found in cheaper plates. We believe in building parts that last a lifetime.

  • Precision CNC Machining: Guarantees a perfect fit for both your slide and your red dot sight.
  • Ultra-Strong 7075 T6 Aluminum: Provides the strength of steel at a fraction of the weight, making it the ultimate material for pistol optic plates.
  • Type III Hardcoat Anodizing: Delivers a rugged, non-reflective matte black finish that protects against corrosion and wear.

Frequently Asked Questions

Will this fit a Trijicon RMRcc?

No. This plate will NOT fit the Trijicon RMRcc. The RMRcc (Ruggedized Miniature Reflex for Concealed Carry) has a unique, narrower footprint designed for slimline pistols. It requires a specific adapter plate made exclusively for the RMRcc footprint.

Will this fit a Holosun 407C, 507C, or 508T?

Yes. The Holosun 407C, 507C, 507C X2, and 508T models all share the exact same Trijicon RMR mounting footprint. Our RMR plates are a perfect, secure fit for these popular Holosun optics, giving you a rugged and reliable mounting solution.

Will this fit a Holosun 507K or EPS Carry?

No. The smaller Holosun "K" series (407K, 507K) and the EPS/EPS Carry models use a different, smaller footprint (Modified RMSc). This RMR plate will not work with those optics. You must use a plate made specifically for the Shield RMS / Holosun K-Series footprint.

What is the difference between an RMR and RMSc footprint?

The Trijicon RMR footprint is the full-size standard, characterized by two large, central recoil lugs. The RMSc (Shield Standard) footprint is a micro-optic standard for slimline pistols. They are completely different sizes and are not cross-compatible. This plate is only for full-size RMR-compatible optics.
