Leapers UTG® OP3 Micro SLS Red Dot 4 MOA – Auto Brightness, Side-Loading Battery (RMR Footprint)
Leapers UTG OP3 Micro SLS Red Dot 4 MOA – RMR Footprint Precision Optic
The Leapers UTG® OP3 Micro SLS Red Dot sight delivers compact, high-performance aiming for pistols, carbines, and tactical rifles with its 4 MOA red single dot reticle, precision-machined from 6061-T6 aircraft aluminum and finished in matte black anodization. Featuring auto and manual brightness modes with 8 intensity settings via a surrounding light sensor, it ensures crisp visibility in dawn hunts, airsoft CQB, or low-light tactical drills—without parallax issues thanks to unlimited eye relief and a large multi-coated glass lens. The side-loading CR1632 battery compartment means no re-zeroing after swaps, while IPX7 waterproofing and 15,000+ hour life at mid-brightness keep it reliable through rain, dust, or recoil-heavy sessions.
Key advantages shine in real-world use: 1 MOA click adjustments for precise zeroing, co-witness height with suppressor irons, and an RMR footprint compatible with most optics-ready pistols like Glocks or Staccatos. At just 1.3 oz (37 g) optic-only or 1.9 oz (54 g) with mount, it adds minimal weight for fast target acquisition on PCCs or hunting rigs. Installation is simple—use the included low-profile Picatinny base with #6-32 or #4-40 screws at 12-25 in-lbs torque, align tertiary laser-etched aiming points, and you're field-ready in minutes. Maintenance involves battery checks and lens wipes for sustained clarity.
