Trijicon MRO HD 1/3 Co-Witness 2/68 MOA Red Dot, Black

Trijicon MRO HD 1/3 Co-Witness Features and Performance

The Trijicon MRO HD 1/3 Co-Witness is a compact red dot optic built for fast target acquisition, rugged durability, and dependable performance on rifles and carbines. Designed around Trijicon’s MRO HD system, this configuration uses a lower 1/3 co-witness mount that allows compatible iron sights to sit lower in the sight picture while keeping the optic’s window clear and uncluttered. That makes it a strong option for shooters who prefer a modern carbine setup with a more open view through the optic.

At the center of the Trijicon MRO HD 1/3 Co-Witness is an adjustable 68 MOA reticle with a 2 MOA dot. This reticle gives shooters a fast and highly visible reference for close-range shooting while still allowing for more deliberate shot placement when needed. With 1x magnification and infinite eye relief, the optic is designed to keep the shooter target focused and moving naturally through transitions, making it especially useful for defensive use, range training, and general-purpose rifle setups.

Built from forged 7075 T6 aluminum with a matte finish, the Trijicon MRO HD 1/3 Co-Witness is made for hard use and long-term durability. Its compact 2.9-inch length and lightweight 4.6-ounce build help it integrate well onto a wide range of rifle and carbine platforms without adding excessive bulk. The black housing and red reticle maintain a clean, professional appearance while reinforcing the optic’s practical, performance-driven design.

Powered by a CR2032 battery, the Trijicon MRO HD 1/3 Co-Witness uses a practical and widely available power source. It also offers a 70 MOA adjustment range, giving shooters flexibility when zeroing across different setups and applications. Its rugged temperature rating further supports its role as a dependable optic for serious use in a wide range of environmental conditions.

Many shooters choose the Trijicon MRO HD 1/3 Co-Witness because it combines a premium reticle system, durable forged construction, and a lower 1/3 co-witness mounting setup in one compact optic. It is a strong choice for shooters who want fast acquisition, dependable performance, and Trijicon’s trusted optic quality on a rifle or carbine platform.
