Trijicon MRO-SD Green Dot Sight – No Mount, Black

The Trijicon MRO-SD (Miniature Rifle Optic – Subterranean Defense) features a 2 MOA green dot reticle optimized for lowlight and night vision compatibility. Built for close-quarters to mid-range engagements, this sealed reflex optic delivers the same proven MRO housing with brightness settings tailored for suppressed firearms and restricted visibility environments. Green dots typically offer better contrast in dim conditions and appear crisper to many shooters than red.

The MRO-SD uses a forged 7075-T6 aluminum housing with fully multi-coated lenses for excellent light transmission and minimal glare. Adjustable brightness settings include both super-bright daylight modes and ultra-low NV-compatible settings. The ambidextrous brightness control sits on top of the housing for quick adjustment without breaking cheek weld. This model ships without a mount—choose your preferred height and interface separately. The sealed design is waterproof to 100 feet and built to withstand recoil from calibers up to .50 BMG.
