How to measure for new mounts for your scope

Lets use a 3-9x50 scope for example: = 50mm lens

1: measure your lens = 50mm

2: half it = 25mm

3: check measurment of mount in product info (in mm from center of mount to base)

4: mount measurment is 40mm

5: add mount 40mm to half lens 25mm = 65mm

6: means maximum 65mm lens

from centre of mount to base of mount it is 40mm
your scope is 50mm so from centre to edge = 25mm
should give you aprox 15mm gap from scope lens to barrel

Please allow for items like Dust, lens covers, fixed sight hood on end of barrel
