The MPO's Non-Obscuring Milling Reticle was designed for competition shooters who need to make precise shots, spot their hits (or misses), and make quick follow-up shots under a time constraint.
The main hurdle we found in designing a first focal plane reticle was having useable crosshairs at mid-power that don't grow too thick at higher magnification or become too hard to see at low magnification. Our solution is the Non-Obscuring Milling Reticle or N-OMR. The N-OMR's main feature is crosshair lines that are open in the center so the shooter can see through them at high magnification. At lower magnification, this makes the lines appear thicker.
The intersection of the crosshairs is left mostly open, except for a small 0.05 MRAD dot. This dot helps the shooter easily center targets and still have a precise aiming point at high magnification. Both the vertical and horizontal crosshairs have a section dedicated to measuring to 0.1 MRADs. This portion is close to the center of the crosshairs so users can get accurate measurements at high magnification.
The main crosshairs are graduated in 0.5 MRAD increments, which minimizes clutter on the reticle while still allowing easy holds down to 0.25 MRADs. The top of the reticle is left open so shooters can spot their own shots (or misses) without obstruction. The lower “Christmas Tree” portion has 0.2 MRAD holdover dots for fine aiming in windy conditions or when the shooter is “on the clock” in competition. Full MRADs are marked with a thicker vertical line.
How To Use This Reticle - An Example
Let's say the shooter is engaging a target at 1,000 yards with a 10 mph crosswind. The shooter determines he needs 10 MRADs of elevation and 1 MRAD of windage. The shooter has three options for achieving the correct hold:
- Dial the windage to 10 MRADs and the elevation to 1 MRAD into the wind and take the shot.
- Dial 10 MRADs with the turret and hold 1 MRAD into the wind using the horizontal crosshair increments.
- Decide speed is of the essence and don't dial at all. Instead, hold 10 MRADs of elevation and 1 MRAD of windage using the reticle alone.
