The Holosun ARO-MRS-GR combines fast sight acquisition with reticle versatility. Its Multi-Reticle System lets you choose between a precise 2 MOA green dot, a fast-acquisition 65 MOA green circle, or the combined circle-dot—giving shooters the flexibility to adapt to changing engagement distances.
Constructed from 7075-T6 aluminum with a matte black hard-anodized finish, the optic is IP67 waterproof and shock-rated to withstand heavy recoil. The fully multi-coated lens ensures a bright, clear sight picture, while the enclosed emitter design provides consistent performance in all conditions.
Powered by a CR2032 battery, the ARO-MRS-GR offers up to 50,000 hours of operation on setting 6. Shake Awake™ technology automatically powers the optic on when motion is detected and turns it off when idle, while retaining the last brightness setting.
The sight provides 12 brightness settings—10 daylight and 2 night-vision compatible—and allows precise 0.5 MOA windage and elevation adjustments with ±50 MOA total travel. Included are a Picatinny mount set for lower 1/3 co-witness and an additional low mount for alternate setups.
