It's an alright mount - SureFire M79 Flashlight 6P / G2 Gun Mount - Universal Clamp Mount 1" Ring

I've read the reviews for this iteam and agree. I to thought it was machined aluminum but was disapointed to discover the mount was injection moulded plastic. I'm a firearms instructor, rifleman, and Trooper of six years. All an all, our dumb asses didn't realize that to adjust the diameter of the mount to fit our respective flashlights... you needed to turn the threaded latch mechanism. The threads allow you to slightly increase or decrease the inner diameter of the mount. We all probaly thought is was a fixed size and tourqued down on the latch.... thus breaking it. When I recieved the replacement, I played around with it and realized my error. It's since been on my Benelli M2, RR M4, 870 Tactical, and KSG. Aslong as you tighten the retention screw with a quarter, the mount holds its own.
Pros: Surefire quality, allows a small variance between diff. diameter flashlight
Cons: My first one snapped, but OpticsPlanet replaced it without question
