Leupold Mark 6 1-6 3 Gun Optic
Mark 6 scopes have 34mm main tubes and feature mil-based ZeroLock™ windage and elevation dials that prevent unintentional adjustments in the field. They are available with different styles of ranging reticles located on the front focal plane (FFP), so the subtensions remain true at all magnifications. The 1-6x20mm allows both-eyes-open shooting without magnification, with the ability to zoom up to 6x for longer shots. It’s available with the illuminated TMR (Tactical Milling Reticle), the CMR-W 5.56 reticle calibrated for military M855 ammo at 900 yards, the CMR-W 7.62 reticle calibrated for 175 grain .308 loads out to 1,200 yards. The 3-18x44mm scope is available with the CMR-W 7.62 reticle, the illuminated TMR, or the Horus H58 mil-based reticle. TMR models require a battery, included, and do not have the FFP feature. 1-6x20mm is 10.3″ long with 5″ mounting space, 3.7″ eye relief and weighs 17 oz. 3-18x44mm scopes are 11.9″ long, have 5.3″ mounting space, 3.8″ eye relief and weigh 23.6 oz.
