The second gen Swampfox Liberator offers some awesome new features. Shake N Wake motion sensing auto on/off, super-efficient crisp 2 MOA dot emitter; and a greatly improved battery life all combine to provide a significant performance upgrade over the gen 1 Liberator . The Swampfox Liberator II 1x22mm Mini Red Dot Sight offers 2 night vision and 8 daylight bright illumination settings. While most red dots come with just one low profile mount, the Swampfox Liberator II comes with both a low profile and an absolute co-witness height 1913 MIL-STD picatinny mount. This optic is small and lightweight, but also rugged and waterproof. This mini optic will handle recoil from 12 gauge shotguns and .308 rifles with no problem. As always from Swampfox, the glass inside and out has premium clarity and multiple coatings: anti-scratch, anti-glare, anti-fog and hydrophobic. It comes in two model configurations, a green dot or a red dot.
