If you’re searching for a UTG OP3 4-16x44, a 30mm compact scope with side parallax, or the exact part OP3-GM4164UMOA (EAN 4717385555747), this model is built to deliver clarity, repeatability, and durability.
4–16X Magnification: A True “Do More” Range for Precision Work
The 4–16X range is a sweet spot for shooters who want:
Enough magnification for small targets and longer-distance hits (16X)
A practical low end for field shooting and quick acquisition (4X)
A versatile scope that can transition from paper/steel to hunting and pest control (where legal and appropriate)
This makes the OP3 4–16X44 an excellent option for anyone wanting more reach than a 3–9X without jumping to oversized, heavy long-range glass. (leapers.com)
Emerald Lens Coatings + Multi-Coated Glass for Crisp Sight Picture
UTG equips the OP3 line with best-in-class Emerald coatings designed to maximize light transmission and enhance clarity. Combined with quality glass, this helps maintain a clean, usable image across the zoom range—especially useful during early/late light windows or mixed background conditions. (leapers.com)
UMOA Etched Glass Reticle: Holds, Ranging, and Real-World Math
At the core is UTG’s UMOA range estimating etched-glass reticle, built to support:
Because it’s etched glass, the reticle remains visible even if illumination is turned off or the battery dies—critical for field reliability. (leapers.com)
UTG also publishes practical subtension details: at 10X and 100 yards, the center cross is 4 MOA end-to-end with 2 MOA hash marks, supporting holdovers up to 50 MOA, hold-under to 20 MOA, and 30 MOA wind holds per side. (leapers.com)
EZ-TAP® IE® Illumination: Red/Green + 36 Colors with Memory
Lighting conditions can change from bright sun to dark timber to indoor ranges quickly. UTG’s EZ-TAP® Illumination Enhancing (IE®) system provides:
Power comes from a CR2032 3V battery loaded at the rear eyepiece. (leapers.com)
SWAT Side Wheel Parallax: 10 Yards to Infinity
For precision shooting—especially with smaller targets or closer-range rimfire/airgun work—parallax adjustment is essential. This scope uses UTG’s Low Top Side Wheel Adjustable Turret (SWAT) with parallax adjustment from 10 yards to infinity, allowing you to fine-tune focus and minimize parallax error across a huge distance range.

Premium Turrets: Zero Lockable, Resettable, 1/4 MOA Clicks
