Descrizione Vortex 1x30 StrikeFire II Red/Green Dot Sight with Cantilever Mount SF-RG-501 The Vortex 1x30 StrikeFire II Red/Green Dot Sight with Cantilever Mount is an unmagnified optic designed for quick target acquisition and tracking from dawn to dusk. The sight has a 4 MOA red/green dot with ten brightness levels, two of which work with night vision, for easy aiming on your target. All of the optics are also parallax free and are multi-coated for increasing light transmission. This sight also has unlimited eye relief for rapid target acquisition. The sight features 1/2 MOA shot correction to put you on-target, with a 100 MOA windage and elevation adjustment range that lets you compensate for most terrain and conditions. Its housing is nitrogen-filled and O-ring sealed for water and fogproof performance in all weather. Built-in front and rear flip-up lens covers protect the optics when not in use, and can be quickly deployed when targets present themselves. This model also includes a cantilever ring mount that positions the optic center 40mm above the base surface and attaches to a firearm via a Picatinny/Weaver mount.
