YHM 22/556 Rifle Thread Protector 1/2x28 .640

The YHM 22/556 Rifle Thread Protector 1/2x28 .640 from Yankee Hill Machine Co is a precision-engineered muzzle component designed to protect rifle barrel threads when suppressors, flash hiders, or compensators are not installed. This thread protector is specifically compatible with .22 caliber and 5.56 NATO firearms, preserving critical barrel threading and preventing damage that could compromise future accessory mounting.

Manufactured from hardened steel, this thread protector resists corrosion and mechanical wear from routine handling, cleaning, and storage, making it a durable choice for various applications. The 1/2x28 thread pitch is the standard specification for these rifle platforms, while the .640-inch diameter is designed to fit properly on compatible barrel profiles.

This thread protector is beneficial for both operators and enthusiasts, serving as a practical barrier against accidental thread damage during transport or field conditions. It is ideal for maintaining prepped barrels for future accessory installations or for use on dedicated range guns between accessory changes. Law enforcement and military units frequently deploy thread protectors to preserve the integrity of newly issued or recently serviced rifles.
