1X Best 260° Ampoint CEU --Rail:21.2mm and central height:30mm

The CEU (Corner Engagement Unit) revolutionizes tactical operations with its 260° rotational design, enabling operators to aim around corners, up staircases, or down tunnels without exposing themselves. Using a dual-mirror reflective system, it delivers a true, non-reversed image with 1X magnification and unlimited eye relief, ensuring seamless target acquisition. Compatible with all sight systems via the TwistMount base, it allows co-witnessing with optics using low/high rise rings. Constructed from high-strength glass-reinforced polymer with anti-reflex coated mirrors, it withstands -45°C to +55°C operation, 25m submersion, and 500G shocks. Weighing just 130g (CEU only), it mounts to Picatinny rails with 30mm/40mm optical axis heights, turning standard weapons into scouting tools. Ideal for military, law enforcement, and CQB scenarios, this NVD-compatible device maintains zero impact on weapon POI while enhancing situational awareness in extreme conditions.

The CEU rotates a full 260° allowing the operator to safely look around either right or left-hand corners, up staircases or down tunnels from almost any angle. To mount the CEU, use the  TwistMount base and choose the CEU ring which allows co-witnessing with the  sight.
