Strike Industries T1 Riser Mount - Lower 1/3 Co-Witness, Flat Dark Earth Finish

The Strike Industries T1 Riser Mount in Flat Dark Earth is a co-witness adapter built for shooters running a red dot on top of a rifle with backup iron sights. This lower 1/3 riser positions your T1-pattern optic at the ideal height to align with the sightline of your backup irons—a setup that's become standard for serious hunters, competition shooters, and tactical carbine builders. If you're running irons as a failsafe while trusting your dot for speed, the geometry matters, and Strike Industries has engineered this mount to get it right.

The Flat Dark Earth anodized finish blends seamlessly with modern tactical rifle builds and resists glare and corrosion better than bare aluminum. Strike Industries is known for precision manufacturing and attention to detail, and this riser delivers the fit and durability you'd expect from a reputable optics mount maker. It's a no-frills, focused accessory—not a quick-detach marvel or a Swiss Army knife—just a solid co-witness platform that lets your backup sights stay in the fight when your primary optic needs to come off or fails.

Whether you're setting up a duty rifle, a hunting carbine with redundancy in mind, or a competition build where iron sight backup is required, this riser gives you a mechanically sound way to stack your optics correctly. The lower 1/3 co-witness height is the modern standard for AR platforms and similar rifles with Picatinny rail systems.

Frequently Asked Questions

What is a lower 1/3 co-witness riser?

A co-witness riser raises your red dot optic so that its optical axis aligns with the sightline of your backup iron sights. Lower 1/3 (sometimes called "lower third") is the height standard that positions the dot so that it sits roughly one-third of the way down the rear sight aperture, allowing you to use irons and optic together or independently. This is the most common setup for modern carbines.

What red dots does this mount fit?

The Strike Industries T1 Riser Mount is designed for T1-pattern red dot optics. Confirm that your optic uses a T1 footprint (also called a Trijicon RMR-type mount) before ordering.

Will this work on any rifle with a Picatinny rail?

This riser mounts to any Picatinny rail system. It's commonly used on AR-15 platforms and other modern rifles with top-rail real estate, but compatibility depends on your specific rifle's rail and your choice of optic.
