Each barrel is magnetic particle tested to ensure that it is free of microstresses or flaws, resulting in consistency and quality in every barrel shipped from the factory.
Bore and barrel are chrome lined to resist corrosion and increased resistance to heat erosion, greatly improving barrel life and reliable chambering and extracting.
M4 style freed ramps and barrel extension provide consisten feeding.
This is a 14.5" barrel and is subject to all NFA rules. Cut for a carbine-length gas system.
