UTG OP3 Micro 4 MOA Green Dot Reflex Sight with Adaptive Base

The UTG OP3 Micro is a compact reflex sight built around a 4 MOA green dot reticle, designed for pistols and short-barreled rifles where a low-profile, lightweight optic is needed. Its purpose-built Docter footprint base makes it a direct mount for slides cut for Docter-pattern optics, while the included adaptive Picatinny base lets it drop onto any standard Picatinny rail with a quick swap.

The housing is precision machined from 6061-T6 aluminum and finished in a matte black anodization that keeps the sight light at just 0.08 lb. The 4 MOA green dot is adjustable through 8 brightness intensity settings for full sun down to indoor low-light, and a single CR2032 battery delivers 20,000+ hours of run time. The sight is rated IPX7 waterproof for dependable performance in wet conditions.

Whether you run it on a Docter-pattern pistol slide or mount it to a rifle with the included low-profile Picatinny base, the OP3 Micro gives you a clean, unobstructed sight picture with unlimited eye relief and intuitive target acquisition. The optic measures 35.8 mm in length and ships with the adaptive base for installation.
