Yankee Hill Machine Co. YHM-3412-B Thread Protector 1/2x28 .640 OD – 5.56/.223/22LR Rifles

This Yankee Hill Machine thread protector shields your rifle's muzzle threads from dirt, damage, and corrosion when running without a muzzle device or suppressor. The knurled cap threads onto standard 1/2x28 TPI muzzle threading common to 5.56 NATO, .223 Remington, and .22 LR rifles, providing a clean, finished look while keeping threads clean and undamaged for future use.

Machined from steel with a black finish, the protector features a .640-inch outside diameter that profiles cleanly with most standard-contour barrels. The knurled exterior allows for hand-tight installation and removal without tools. Compatible with any firearm using 1/2x28 threading, including AR-15 pattern rifles and many bolt-action rimfire rifles.
