Yankee Hill Machine Co .308 Rifle Thread Protector 5/8x24 .725 OD

This thread protector shields your rifle's muzzle threads from damage when a muzzle device or suppressor isn't installed. The 5/8x24 TPI threading is standard for .308 Winchester and 7.62 NATO rifles, and the .725-inch outer diameter provides a clean profile that matches most .308 barrel contours. Thread protectors prevent corrosion, dings, and cross-threading that can make installing brakes or suppressors difficult later.

Machined from steel with a black oxide finish for durability and corrosion resistance. Simply hand-tighten onto clean threads—no thread locker or excessive torque required. Remove before installing any muzzle device. The .725-inch OD matches standard medium to heavy barrel profiles on AR-10 pattern rifles and bolt-action .308 platforms.
