Full description


The Rhino 4x32 Scope is a fixed magnification optic with a few tricks up its' sleeve. It's essentially a modern day equivalent of the ACOG design, keeping much of the original design that makes it so attractive. The optic itself is fixed at 4x magnification, which is the ideal level of zoom for most Airsoft engagements. The adjustment turrets can be found at the top and right side of the sight, and take the form of concealed turrets protected beneath threaded caps. This design helps keep dust and debris out of the internals of the sight, ensuring it functions as it should. Once the threaded caps have been removed, the sight can be adjusted for windage and elevation using a flat head screwdriver.

Should the fight get close and personal, the backup Red Dot Sight can be used to engage targets quicker and more efficiently. This backup sight can be adjusted for Windage/Elevation from its own set of controls. If you would like more details on the backup Red dot sight, see its description here. The scope has two very short 20mm side rails which can be used to add Lasers, Lights and other tactical gubbins to enhance the function of the sight; an additional rail is present on the top of this RIS version. An illuminated reticule makes the sight much easier to use in the dark or bright woodland, giving you the ability to illuminate the center dot (or Point of Impact) to five varying degrees of brightness. The sight is permanently mounted on an integrated 20mm Mount, which allows you to attach the sight to any 20mm RIS/RAS/Picatinny Rail System.

The reticule of the main sight is a typical Mil-Dot layout which is easy to read/use, and allows you to make last second adjustments to your shots, based on how your previous shot landed. This sight picture can be adjusted for windage/elevation by removing the protective caps and using a flat head screwdriver to make adjustments. The backup Red Dot Sight can be adjusted by making use of the included Allen Keys.
