This Kill Flash is for 4x32 ACOG scopes. This anti-reflection device uses a metal honeycomb mesh structure housed in strong plastic to provide a clear line of sight when looking through the sight directly, while blocking the view of the lens from an angle.
It fits pretty well, no need to screw out the hood to install to put it on
It also protects the Scope lens from mechanical damage (BB's).
Anti-Reflection Device stops your lens giving away your position
Attaches via a heavy duty band around the base of the scope.
