ACOG 4x32 USMC for M4 w/TA51 Mt

The TA31RCO is an Advanced Combat Optical Gunsight ACOG designed for the M4 and M4A1 weapon system 14.5 barrel. It incorporates dual illumination technology using a combination of fiber optics and self-luminous tritium. This allows the aiming point to always be illuminated without the use of batteries. The tritium illuminates the aiming point in total darkness, and the fiber optic self-adjusts reticle brightness during daylight according to ambient light conditions. This allows the operator to keep both eyes open while engaging targets and maintaining maximum situational awareness.brbrDesigned to the exact specifications of the United States Marine Corps, the unique reticle pattern provides quick target acquisition at close combat ranges while providing enhanced target identification and hit probability out to 800 meters utilizing the Bullet Drop Compensator.brbrNo tools are needed for windage and elevation adjustments because the TA31RCO features external adjusters, making it waterproof up to 11m without the caps. Mounting bosses are integrated into the housing by the eyepiece to allow the easy addition of a Trijicon RMR not included.brbrThe TA31RCO-M4CP also includesbrbr- 1 Thumbscrew Flattop Adapter for Picatinny Rail TA51br- 1 killFLASH Anti-Reflection Device TA91br- 1 Scopecoat TA96br- 1 Lens Pen TA56br- 1 Lanyard Assembly for Adjuster Caps TA71Ebr- 1 Trijicon Logo Sticker PR15br- 1 RCO Manualbr- 1 Warranty CardbrbrSpecifications brbr- Magnification 4xbr- Objective Size 32mmbr- Bullet Drop Compensator Yesbr- Length 6.7 with ARDbr- Weight 15.8 oz. with mount and ARDbr- Illumination Source Fiber Optics & Tritiumbr- Reticle Pattern Chevron with Target Reference Systembr- Day Reticle Color Redbr- Night Reticle Color Redbr- Calibration 0.223 14.5 barrelbr- Bindon Aiming Concept Yesbr- Eye Relief 1.5br- Exit Pupil 8mmbr- Field of View Degrees 7br- Field of View at 100 yards 36.8br- Adjustment at 100 yards clicksin 2br- Mount Comes With Flattop Thumbscrew Mount TA51br- Housing Material Forged Aluminum
