Owen V. ★★★★★ Aug 18, 2026

The K-Clamp mounting tech is the real deal, held zero through a solid 300 rounds without budging. Weighs almost nothing on the rifle, and the anodizing matches the upper perfectly.

Violet ★★★★★ Aug 18, 2026

Installed this riser and the 2.26” centerline puts my optic exactly where it should be for a heads-up position. The 7075-T651 aluminum feels rock solid and the hardcoat anodizing is a perfect match.

Timothy L. ★★★★★ Aug 16, 2026

The titanium K-Clamp mounting tech locks down rock solid with zero wobble after a full day at the range, and the Type III hardcoat finish looks like it'll shrug off anything. Took a few minutes to torque it to spec, but once it's on, the lower 1/3 co-witness lines up perfectly for my setup.
