NcSTAR - 3x30 Fixed Sight Magnifier With Mount - Black is a sight picture magnifier, designed to be mounted behind Red Dot and Holographic Style Sights to provide a zoomed picture. The Sight and Mount are both constructed from hard wearing Alloy, and is designed to work on a Real Steel Firearm, making it highly durable. The Sight is Fog, Water and Shock Proof, and features a Prismatic Lens for the Highest Quality Image. The Magnifier features an adjustable Focus Ring, allowing you to focus in on details at a distance, with easy tweaking from around the viewing lens. The Magnifier is equipped with the ability to be adjusted in the Windage and Elevation Directions, allowing it to be used with a variety of different Sights. The mount features a Hand Screw, allowing the sight to be placed and removed from the Rifle without the use of any tools. This sight is perfect for those Airsoft Skirmishers who have a T1 or EoTech sight, and wish they had that little bit more magnification to be able to see targets at a distance.
