If you are looking to purchase this item, please visit our UK store
The Zero Compromise Optic ZC527 is 387mm (15.24 inches) long, weighs only 1075g (37.9oz) and reaches 35 mil in elevation adjustment and 21 mil in windage adjustment.
It is in a class of its own!
Of all other optics in this magnification range, a very generous field of view of 7m / 100 meters (21ft/100Yds) results in one of the widest in the industry.
Outstanding light transmission and exceptional resolution are just two attributes of the best optical design ever developed, perfectly complementing the very best mechanical properties in the industry.
Our goal is not to build Rifle Scopes.
We strive to build the absolute best riflescopes in the world!
We don't compromise on quality, we simply use the best materials and techniques to create the scope you have always dreamed of.

Every ZCO product places the reticle in the First Focal Plane of the optical system. This means that the reticle stays the
the same size in relation to the target no matter the magnification setting.
Whether you are using a mil radian (MIL) or Minute of Angle (MOA) reticle, it is important to remember this is simply an
angular unit of measure. This angle is the same no matter the distance; 1 MIL at 100 yards is also 1 MIL at 500 yards and 1 MOA at 100 yards is also 1 MOA at 500 yards.
This is important for making corrections to the elevation or windage turrets through the observed impact of the bullet downrange, no matter the distance, as well as for range estimation with the reticle.
Follow the desired formula below to determine your target distance:
MIL
1. Target size in inches x 27.77 / Target size in MIL = Target distance in Yards.
2. Target size in inches x 25.4 / Target size in MIL = Target distance in Meters.
3. Target size in cm x 10.93 / Target size in MIL = Target distance in Yards.
4. Target size in cm x 10 / Target size in MIL = Target distance in Meters.
MOA
1. Target size in inches x 95.5 / Target size in MOA = Target distance in Yards
2. Target size in inches x 87.3 / Target size in MOA = Target distance in Meters.
3. Target size in cm x 37.60 / Target size in MOA = Target distance in Yards.
4. Target size in cm X 34.38 / Target size in MOA = Target distance in Meters.
Follow this example:
You know a steel target downrange measures 18” x 24” and a mil reading with the reticle in your scope gives 1.00 MIL
and 1.33 MIL respectively, and you want the distance to be in “Yards.”
18 x 27.77 = 499.86 Yards 24 x 27.77 = 501.11 Yards
1.00 MIL 1.33 MIL
In this example, we could figure for a 500-yard target distance. Obtaining accurate mil readings through the scope takes
practice, and the more accurate the reading, the more accurate the calculated distance.
Since the reticle is in the First Focal Plane (FFP) and we know that mils or MOA are an angular unit of measure, we can
make fast and accurate corrections to the elevation or windage turrets on the scope when we observe bullet impact downrange that is not where we want it to be. The reticle now essentially becomes a magnified ruler and is accurate no matter the distance.
Place the crosshairs where you want the bullet to impact, then observe where the bullet actually went. Read the reticle for both vertical and horizontal displacement (MIL or MOA depending on the reticle) based on actual bullet impact. If the group needs to come up and left, for example, dial the exact amount on the elevation turret in the UP direction and LEFT on the windage turret as measured with the reticle
