Sightmark Ultra Shot M-Spec FMS Reflex Sight

The Sellmark Sightmark Ultra Shot M-Spec FMS Reflex Sight (Sellmark part no. SM26035) steps up from the standard Ultra Shot with a magnesium alloy body for even lighter weight without giving up strength. The 65 MOA circle-dot-crosshair reticle combines a 60 MOA circle with 5 MOA subtension and a 2 MOA central dot, giving shooters a fast circle for close targets and a precise dot for distance in the same sight picture. IP68 waterproofing rates the sight to 40 feet, well beyond the water resistance of most reflex sights, and a maximum recoil rating up to .50 BMG means it holds up to genuinely hard-recoiling rifles.
