Suggestions for M4 Light and Light Rail for fore end. in Benelli Posted January 12, 2016 I've paid more and gotten less with other light mounting solutions. I think I paid nearly the same amount for the Surefire M80 rail, and hated it. The price is high, but you are buying a quality made CNC machined item made here in the US. These aren't extrusions like most of the other offerings. Plus this won't interfere with disassembly of the weapon like most of the other options out there. Get the carriercomp spring/follower and preferably one of their magazine tubes. My older setup, the Surefire Outdoorsman body/tailcap and a M600C Scout head. I've swapped the head for a 500 lumen M600U head. Currently it and the mount are out being painted in Burnt Bronze Cerakote. Here is a M600C 200 lumen head's barrel shadow. The 500 lumen model is similar, you just have a further throw. In the field, I don't even notice the shadow. Thank you very much! The picture helps tremendously.
