Trijicon

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 3x30mm model is designed for law enforcement and military applications, where the combination of ample magnification, low light capability and long eye relief make it the ACOG of choice. This ACOG features a dual illuminated red crosshair 300 AAC Blackout 115/220GR ballistic reticle (for subsonic and supersonic rounds) and includes a TA60 flattop mount.
