If you'd like to own one of the most accurate AKM/AK-47 barrel models anywhere, take a look at this U.S.-made chrome lined AKM barrel. These barrels are chrome lined to add accuracy and longevity and are designed to fit a variety of
old Eastern Bloc-made AKM (7.62 X 39mm) models. This includes use as upgraded barrels for Romanian, Polish, Russian, Egyptian and Hungarian AKMs.
You'll find that it fits all AK-47 standard muzzle brakes with its 14x1 left-hand
threading. Gas ports have been pre-drilled. This unit has proven itself to be extremely accurate and also quite user-friendly for those doing rebuilds. It’s been used successfully on many rifles out there.
