Sightmark Ultra Shot M-Spec FMS is a full-size reflex sight built for fast shooting and demanding conditions. Large viewing window, multiple reticle options, and rugged construction make it suitable for rifles, shotguns, and other platforms where speed and durability matter.

Fast target acquisition

The wide lens (33 × 24 mm) gives a large field of view, making it easier to pick up targets quickly and track movement. The circle-dot reticle (2 MOA dot with 60 MOA circle and crosshair) helps combine speed and control, especially during transitions or dynamic shooting. :contentReference[oaicite:0]{index=0}

Built for hard use

Constructed from 6061-T6 aluminum with a reinforced housing, designed to handle recoil up to .50 BMG. Shockproof, dustproof and waterproof (IP68), with drop resistance up to 2.4 m. This is a setup that holds zero even under rough handling and heavy recoil. :contentReference[oaicite:1]{index=1}
