Description
The Yankee Hill Machine Thread Protector is a steel cap that covers the threaded muzzle of an AR-style rifle barrel when no muzzle device, flash hider, or suppressor is installed. It keeps the threads clean and undamaged between uses and is intended for AR-15 platform rifles chambered in .22 LR or 5.56x45mm NATO.
The protector is machined from steel with a matte black finish and is knurled for a secure grip during installation and removal. It threads onto standard 1/2-28 barrels and has a .720 inch outside diameter, matching common AR-style muzzle profiles.
