Eli N. ★★★★★

The eye relief is generous enough that I don’t have to smash my face into the stock, and the glass stays crystal clear even at the edges. For something this compact, it punches way above its size class—perfect for keeping the rifle light without losing that 3x reach.

Henry M. ★★★★★

The miniaturized body is what sold me—it mounts so cleanly and doesn’t throw off the rifle’s balance. Clarity at 3x is crisp, and it’s been holding zero through a couple of range days. Only wish it came with a slightly longer mount for my setup, but that’s a minor tweak.

Daniel ★★★★★

Mounted this behind my red dot and the eyebox is way more forgiving than I expected for something this tiny. The push-button flip mount locks up tight with no wobble. Glass is clear edge to edge.
