Product Description

Nikko Stirling 1″ Dovetail High

Fits weaver/picatinny base (20-21mm) width. See http://www.tacticalscope.co.uk/blog/?p=50 if unsure how to determine what you have.

1″ (25mm) tube scope

Medium – Distance from base of mount to bottom of ring (the saddle) is 13.8mm (0.53″)

Additionally, based on scope being fitted onto a flat base rail and scope lens objective being flush to the gun body

Maximum outer scope case size = 52mm.
This equates to an approx. maximum scope lens size of 42mm as most scope outsides add around 10mm.
Can be more than 10mm if chunky flip up lens caps are being used so please take this into consideration and go up a size if in doubt.
However if the end of the scope will hang over the end of the stock or if the rail is raised then larger lens scopes can be accomodated.

Finally, machined from Aircraft Aluminum Alloy with Twin screws top and bottom for secure scope and rail grip and no recoil or scope shift
