I had a MI extended rail for my SCAR17, and decided the length and weight didn't suit my uses for the gun, but the OEM rail was too short for mounting a light and VFG comfortably, so I put it under a chop saw and ended up with what I consider the ideal rail for general use. It covers the gas block assembly and gives you just enough room to mount accessories without extending too far and adding too much weight. I might have gone for a Branham rail if they were available, but I suspect this might be lighter, but I don't have a way to compare them.
