Trijicon 4x32 ACOG Rifle Scope w/ Colt Knob Thumbscrew Mount TA31-D-100581, Color: Black — Free 2 Day Shipping w/ code 2DAYAIR

As one of the most well-known Advanced Combat Optical Gunsights (ACOG), the 4x32 TA31RCO-M855 from Trijicon uses advanced technology to help with target acquisition and optical clarity. To achieve this, it uses a combination of fiber optics and self-luminious tritium, allowing the aiming point to always be visible without the use of batteries. This is because the tritium illuminates the aiming point in total darkness, while the fiber optic self-adjusts the reticle brightness during dayling according to ambient lighting conditions. This means you can keep both eyes open while acquiring targets and aiming through the optic, even when you are moving between varying brightness levels. This improves your depth perception, accuracy, and situational awareness, making it the perfect optic for tactical situations.

Originally designed to meet the exact specifications of the United States Marine Corps for their M16A4 and M16M4 weapon systems, the unique reticle pattern provides quick target acquisition at close range, as well as enhanced accuracy and identification at up to 1,000 meters. It is also waterproof up to 11m and doesn't require special tools to adjust for windage or elevation because it features external adjusters.
