Works for my application, almost perfect - Surefire Classic Universal Weapon Light System Weaver Mount For 1.0" Diameter Tubes M12

I wanted a mount to attached a light to a scope on a .243. This is the only reasonably priced mount I could find. It works, but the one-slot Weaver section does not fits the slot perfectly for a Picatinny style screw. I just took a round file to the slot to make it a little bigger to fit the thumbscrew.
Pros: Hard to find application
Cons: Needs some custom tweaking
