I have a 15" evo on a 18" build. Great rail, solid lockup. Mostly a rnage only build, and hasn't given me any issues. It is a pretty wide rail, similar to the Troy series.
Great custome cs too. I've had a Rainer Arms Samson evo 12" too. No issues with that one either.
My friend had a 556 Tactical 15" that he over torqued and broke, Samson hooked him up with a new on no problem.
