UTG® OP3 3-12X44 30mm Compact Scope, AO, IE®, Glass UMOA

The UMOA reticle features hash marks at minute of angle increments for precise range estimation and bullet drop and wind drift compensation. This reticle is the best choice for long-range precision shooters who want clear adjustments and to rapidly calculate holds. The reticle’s center crosshair can be illuminated to assist aiming under different light conditions.

At 10X magnification at 100 yards, the reticle provides a 4 MOA (from end to end) center cross and equally distanced hash marks at 2 MOA increments all the way up to 50 MOA for holdover, 20 MOA for hold under, and 30 MOA on each side for wind drift. The center cross can be illuminated to assist aiming under different light conditions.

2. Range estimating requires common knowledge of your target’s actual width and or height.

3. Set your scope at 10X magnification or the highest power of your particular scope should your highest power be below or above 10X magnification. View the target through the scope. Estimate the height or width of the target in MOA by determining how many hash marks the target spans.

4. Once the target’s height or width has been measured in MOA, use the following formula to estimate the distance to the target. An example scenario is provided to you below for reference.

The length of an animal from shoulder to tail is 40 inches (1.016 meters). We see through the scope at 9X magnification that the animal spans 20 MOA. The distance to the animal can be derived using the formula below.

(1.016 x 3,438/20) X (9/10) = Range in meters to the animal
157.2 = Range in meters (or 172 yards) to the animal
