Back in the early 2000's I bought an LMT rifle with a 16" piston barrel that had accuracy issues (2 -3 moa at 100 yards doesn't cut it for me). I know LMT has made great strides over the past two decades but am curious if anyone has any of their new piston uppers and what kind of accuracy you're getting with match grade 5.56 ammo? I would like to be able to ring steel out to 600 yards with this setup and I like piston uppers because I almost always shoot suppressed and pistons are a lot cleaner than DI; however, if by going piston means I'll sacrifice accuracy then I'll just deal with the carbon build up and stick with DI.
