High-Quality Stainless Steel Replacement Barrel
Stainless steel replacement barrel for the 580 Series Mini-14 and newer Ranch Rifles can also be used to upgrade an old series Mini-14 to a barrel with the heavier contour (requires installation of .625" gas block, available separately). Comes with pre-installed, factory-height front sight assembly that will work with standard factory rear sight. Gunsmithing required—barrel must be properly indexed and final reamed for proper headspace.
