Ryohin Buhin Evolution Gear SRO Replica Dot Sight, Compatible with 20mm Rails, with Low Mount, RMR Mount Compatible, Reflex Sight, Red Dot Sight

[Compatible Airsoft Guns] ■Compatible with all airsoft guns with 20mm rails. [Mounting Ease] ★☆☆☆☆ | Includes a low mount compatible with 20mm rails. Easily attaches with two hex screws. When mounting on M4/MP7 rifles, we strongly recommend using a separate "riser mount" (such as the UNITY RISER MOUNT)! (It's too low and difficult to aim. It can also be used with AKs and P90s.) [Battery Requires] 1 x CR2032 button cell battery (sold separately). Please use a new battery. Used or unused batteries may discharge and malfunction. [Mounting to Handguns] Compatible with handguns with the separately sold "RMR Mount Base for Handguns." [7075A Aluminum Alloy + Hard Anodized] The body is made of 7075A aluminum alloy, boasting the same strength and lightness as the original. The surface is resistant to scratches and abrasions and features a luxurious matte finish with a beautiful "hard anodized" finish. [Ultra-realistic engraving] Even the 3D logo engraving and welding marks are realistically reproduced.
