Much has been posted on this site about the Milspecs, but I'm compelled to be redundant. Based on three (308's) used for factory class competition owned over a ten+ year period and one more recently acquired 300WM, which continues to be my go-to LR rig for large game, I would answer YES! All my MilSpec rifles were sub .5MOA with little fuss, clean quickly, and hold accuracy for at least 200 rounds between cleanings. Put a bore scope in a MilSpec barrel, then compare it to.a standard fare Remington, or most any other factory class barrel from the usual suspects.
