The Backup Tactical Thread Protector 1/2×28, Flag Pattern (Backup Tactical part number FLAG) is a custom thread protector that adds a bit of personality to an otherwise purely functional part, machined with a flag pattern on its face. Thread protectors keep a barrel’s exposed threads clean and free of dings whenever a suppressor, muzzle brake, or compensator isn’t mounted, preventing grit and impact damage that can make a device harder to thread on cleanly later. Cut to the common 1/2×28 pitch found on most 5.56/.223 and 9mm pistol-caliber barrels, it threads on and off by hand for quick swaps.
