considering deconstructing a marginal wilson combat barreled 6.8 SPC to build a LW accurate 5.56, thinking 18 inch, I have a Noveske "LW" 18 inch which is not light weight. Something that would shoot at least MOA with 77 grain match king loads. Thinking a criterion barrel if I could find one or who makes an 18 inch LW accurate upper if such a thing exits! Thoughts? The Noveske shoots ok its just a bit on the heavy side for what I want, and done with the 6.8.
