Trijicon 100390 ACOG 4x 32mm Obj 36.80 ft @ 100 yds FOV Matte Black Finish Illuminated Green Crosshair 223

Trijicon's ACOG (Advanced Combat Optical Gunsight) is a fixed power, compact riflescope with an illuminated reticle pattern for use in bright to low/no light with legendary durability and reliability. Every feature of its design was chosen for a single purpose, to provide increased hit potential in all lighting conditions. Fewer moving parts than a variable optic equals more durability, and the forged 7075-T6 aircraft-aluminum-alloy housing provides for a nearly indestructible sighting system. Multi-coated lenses provide superior clarity and light-gathering capabilities with zero distortion. The ACOG is dry-nitrogen-filled to eliminate fogging and waterproof to 100 meters. It is shock-resistant, proven to withstand recoil from 22LR up to 50 BMG, and easily passes U.S. military drop test requirements.

• The 4x32 LED ACOG offers LED reticle illumination powered by a single AA battery. Users can select from six adjustable brightness levels with an "off" between each setting. The body has been optimized by moving the RMR mount forward to maximize its performance in conjunction with the ACOG. It includes Trijicon's TA51 mount which uses two thumbscrews to mount your ACOG to a Picatinny rail.
• This model has a green LED-illuminated .223 crosshair reticle.
