The Cyelee Calf V2 is an entry-level pistol red dot that delivers reliable performance without the compromises typically associated with lower-priced optics. It features a 3 MOA red dot, a 24x17mm window, and 10 adjustable brightness settings including two night vision levels, matching the core spec set of optics in higher price brackets.The Calf V2 mounts on pistols using the Doctor/Noblex footprint and is built from aircraft-grade aluminum with a sealed, waterproof housing. Top-loading battery access and Shake Awake technology keep the optic ready without manual intervention. A single CR1632 provides up to 50,000 hours of battery life.
