The UTG OP3 Micro is a miniature red dot reflex sight with a 4 MOA dot and the Doctor optic footprint. It ships on a low-profile Picatinny base, so it goes straight onto a rail, and the Doctor footprint lets you move it to a slide or plate cut for that pattern.
The housing is precision machined from 6061-T6 aluminum and finished in matte black anodizing. It is a tough, compact optic at an affordable price, and a good pick for a carbine, a pistol-caliber build or a piggyback mount over a magnified optic.
Features:
Before you mount it: If you are going to a slide or adapter plate, confirm it is cut for the Doctor footprint. Zero the optic at your preferred distance and recheck the mounting screws after your first range session.
