So here I am, pondering a ground up 11.5" 5.56 pistol build. I've looked at, read and researched barrels to the point I can't decide. I want the best buck accuracy I can get from barrel "quality" If I go this route, obviously, weight is not my concern. I picked up a Colt Socom heavy barrel that I thought about having cut down and open the gas port. Then again, I read cutting a chrome lined barrel can cause later issues at the crown. Thoughts or barrel recommendations?
