Aimpoint Carbine Optic (ACO) 1x Red Dot Sight with 2 MOA Dot
The Aimpoint Carbine Optic (ACO) is a 1x, non-magnifying red dot sight built around a 30 mm aluminum alloy sight tube and a fixed-height, one-piece mount for direct Picatinny rail installation. The 2 MOA red dot and 10-position rotary intensity control keep the setup simple while maintaining constant-on runtime up to 10,000 hours on a single DL1/3N battery.
This ACO is configured with an AR-height mount that places the optical axis at 39 mm above the rail for an absolute co-witness with standard AR-15 iron sights. Includes the original box and owners manual.
