Specifically built for the AR platform, the Wolverine 1x28 FSR LQD Red Dot Sight offers a generous 28mm objective lens and a 2 MOA aiming dot with 10 brightness levels (including two that are compatible with night vision gear) for close-range engagements, whether tactical or recreational. Impact point adjusts at 1/2 MOA per click, with 120 MOA total elevation and windage adjustment ranges. This optic is so efficient it can run for a million hours on one AA battery, with the reticle on its lowest setting; runtime on level 6 is 50,000 hours, and you'll get 900 hours out of the battery if you use the brightest setting all the time. The Wolverine is built for the rigors of the field, IP67-rated water-resistant, submersible to 3.3', and recoil tested to 800 Gs.
