I have the 4 port LMT brake with xeno mount. I was noticing that the end of the brake was shiny and the first baffle in my scythe ti was also. Investigated it and realized that it was not able to fully seat on the taper. I can either cut the brake down to a 3 port( i wouldn't think this would have any effect on accuracy) or they sell a single port, don't really want a single, but may have to.
