Velcro Barrel/Scope Mount

Not for the Osram L21B torches
 
Rubber Velcro Mount for the Barrel or Scope 

The small end fits up to 25.4mm (1 inch) and the large end up to 32mm. The rubber flexes out a bit to accommodate, but isn't an issue. 
 
Quite a popular mount this one.
 
The straps are quite long, so you can cut them to the right length if required.
 
Please note the clearance of the torch head and scope. The torch in the photo is a Sofirn C8 (same size as my Convoy C8+ and Osram C8+). Scope in the photo had a 40mm optic and measured 46mm outer diameter.
 
 

Includes:

1 x Flashlight/Torch Gun Mount
