I am using a barrel/magazine picatinny style clamp. I already know which one i am purchasing, however I need to find a very heavy duty flashlight ring. I need a ring to mount on my rail that will hold the light in the ring securely and be able to take abuse. I was looking at this ring...this is a style I like. I just dont know who makes this particular one. Does any of any suggestions for a heavy duty flashlight ring?
