Liberator II keeps everything we liked about the original Liberator, while stuffing the inside with upgraded technology, like new emitters with greatly improved battery life and Shake 'N Wake motion sensing auto on/off. The first two brightness settings are night vision compatible, with the following 8 further settings daylight visible. Liberator II ships with two 1913 MIL-STD Picatinny mounts for use on a variety of platforms and the scope body is compatible with industry standard micro dot mounts. Small and light but tough, Liberator II is rated for 800 Gs of shock, so it's a great fit for 12 gauge shotguns and .308 rifles. Liberator II is waterproof, fog resistant and features hydrophobic & anti-scratch coatings on the anti-glare lenses. Battery Life : 25000 hours Brightness Settings : 10 settings Finish : Black Night Vision Compatible : Yes Power Supply : CR 2032 Reticle : Multi-Reticle System Sight Type : Red Dot Weight : 0.22 lbs
