Full description


Externally this scope is based on the ELCAN M145C 3.4x scope, designed as an optic for support weapons like the M249, and assault rifles. The scope is constructed from Alloy and features a Rubber casing to protect it from damage and debris. The scope features an intermediate 4x magnification making it an excellent optic for use in outdoor skirmishes on Airsoft assault rifles and support weapons, sitting perfectly in-between non-magnified red dot sights and high-magnification sniper scopes. This M145C replica features an accurate recreation of the real M145C's tri-needle reticule, which allows users to quickly and accurately locate, track and engage targets. The scope is mounted onto Airsoft weapons by hand using the 20mm RIS mount included in the box. The scope is fully adjustable for windage and elevation and the top of the sight features backup ironsights, should your target to come too close to use the scope. If you're looking for an intermediate magnified optic for use on an Airsoft assault rifle or support weapon, the ELCAN Specter M145C is a perfect choice.
