FPM Gunworks Whistling Bunghole .30 / 7.62mm Thread Protector 5/8x24 Black DLC

The FPM Gunworks Whistling Bunghole is a compact thread protector built for .30 caliber and 7.62mm platforms using a 5/8x24 thread pattern. Made from 17-4 stainless steel and finished in black DLC, it offers a durable, low-profile option for protecting muzzle threads when a muzzle device or suppressor is not installed.

With its short 0.90 inch overall length, this model is a practical fit for shooters who want a clean-looking thread protector that adds durability without unnecessary bulk. It is a strong option for rifle builds, replacements, and general maintenance where thread protection and a refined finish are both important.
