The Cyelee CAT0-G brings the premium green emitter from the CAT G PRO into an accessible carry optic, combining extra brightness with twice the efficiency of Cyelee&';s red emitter. It is built from 7075-T6 aluminum with a large window, recessed buttons, and a top-loading battery tray found typically only in higher-priced optics.The CAT0-G fits pistols with RMSc cuts, including 407K and 507K slides, and is suited to both carry and home defense use. Shake Awake technology activates the optic on any movement with no manual steps required. Sealed waterproof construction and a 50,000-hour battery life keep it ready in any conditions.
