I got the heavy variable mass for my large frame, because I plan to suppress. After 0 rounds fired mine still looks brand new without going KAC I probably couldn't have spent more, but that's not really the goal. LMT also makes great stuff. I was talking to craddock precision a month or so back, and I'm fairly sure he mentioned something about azimuth was who they were using in house.
