True to an extent... but not in the case of an unchromed SU barrel vs. a standard 20" AR barrel. You would have to go to something like a $400 - $500 Douglas or Kreiger barrel to see an increase in accuracy from an unlined barrel over the chromed.Flyer said:Nope. At least, mine's not.
Possibly they'll have lined barrels in the future. There ARE upsides to a un-lined barrel, though... such as increased accuracy!
