These barrel thread protectors are designed to safeguard your firearm's threads when a suppressor or muzzle device isn't installed. Machined for a precise fit, they prevent damage, dirt, and wear that could compromise thread integrity. Available in black or silver finishes, they combine durability with a clean, professional look. Offered in sizes ranging from 0.600" to 1.000", these measurements correspond to the diameter of your barrel. Depending on your firearm, the protector may sit perfectly flush, protrude slightly, or recess slightly from the barrel surface- but will always provide secure coverage. Choose between multiple thread patterns to match your setup and keep your barrel threads safe in storage, transport, or everyday use. Note: Diameter selection corresponds to the diameter of the barrel you are putting this thread protector on.
