Doing a 13.7 build and I am in the midst of figuring out which rail I want to use. Using a BCM stripped upper so wanted to also use a BCM MCMR MLOK rail. My concern is that this rail, while measuring at 13 inches, actually extends out to 13.4 at the flared portion. Using a KNOX on this build. My concern is if I end up adding a can that I will run into clearance issues. Anyone have any experiences?
I had to shave the front of my 13in MCMR down. All you have to do is take the "wave" off the front of the MCMR so its flat on the front. I can get my Dead Air Sandman K on there with about 1/4in clearance.
