The Cyelee Bull PRO is a competition-grade red dot engineered for drop resistance and fast target acquisition. It is drop-tested and rated drop-proof for 6-foot drops, optic-down, on pistols up to 45 oz on concrete, and has survived direct optic-down drops on full-size rifles. The large window and 3 MOA dot are tuned for maximum speed on the competition stage.The Bull PRO mounts on pistols using the RMR footprint and is built from aircraft-grade 7075-T6 aluminum. Motion Deactivated Standby activates the optic on movement and conserves battery during inactivity. Ten adjustable brightness settings including two night vision levels and a 50,000-hour battery life from a CR1632 make it suitable for training and competition.
