Trijicon’s ACOG 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. Includes 3.25 MOA RMR Type 2 attached with mount thumbscrew flattop adapter LENSPEN lanyard assembly for adjuster caps Trijicon logo sticker ACOG manual and warranty card.
