Rusan ARK2 adapter for Pulsar Krypton/Proton 58mm (outer dia.)

High-quality ARK2 adapter from Rusan for mounting Pulsar Krypton and Pulsar Proton thermal imaging clip-on devices on riflescopes with an objective lens outer diameter of 58mm.

The adapter has smooth adjustment of the display position relative to the field of view of the daytime scope, and thanks to its thin walls, only 3mm of clearance between the scope and the barrel is needed to mount it on the sight.

Mounting on the scope's objective lens is done with a lever and is very intuitive.

An objective lens tube outer diameter of 58mm is found, among others, on Delta Optical Titanium/Titanium HD series scopes with an objective lens diameter of 50mm.
