The U.S. Optics MR-10H425 1.8-10X

Shop Defensor Tactical for the U.S. Optics MR-10H425 1.8-10X, The MR-10H425 1.8-10X, has a 12-position, MIL scale Illuminated Reticle System (IRS) is optimized for target engagement at medium range distances and when engaging targets at medium range in low light conditions.  

Proprietary thin film coatings fused to precision-ground and polished lenses project sharp image resolution at over 85% light transmission beginning from the objective lens through the eyepiece to ensure a crystal clear sight picture even in low light conditions. 

Adjustable eyepiece with a range of +2 to -3 diopter ensures a sharp and distinct reticle image. 

32mm eyepiece and a 37mm objective at 1.8X magnification yield a 4mm exit pupil for rapid deployment of the IRS over a target. 

At 1.8X magnification the field of view at 100 yards spans 41.6 feet for maximum situational awareness through the sight picture. 

At 10X magnification the field of view at 100 yards spans 12.8 feet for maximum situational awareness through the sight picture. 

Low-profile Erector Repositioning Elevation Knob (EREK) is easily manipulated in any environmental condition including cold and inclement weather, with or without gloves. 

EREK incorporates a center screw for rough zeroing allowing maximum upward travel of 90 distinct, positive clicks per revolution in 1/10 MIL increments when adjusting the MR-10MIL elevation with the EREK.

Turret Parallax Adjustment Locater (TPAL) knob corrects perceived image shift, or parallax, at distances as near as 30 yards to infinity. 

US#1 windage knob with 48 distinct, positive clicks per revolution facilitates adjustment in 1/10 MIL increments.
