The Clip-On Eyepiece is the perfect tool to convert your existing thermal or fusion rifle sight to a clip-on sight for use with an existing daytime scope. Conversion takes only a few seconds. Outside thread is M52x0.75 which makes it suitable for a variety of standard clip-on adapters (also known as "clamps") to attach directly onto your daytime scope.
