A thread protector is a small part that saves a big headache. It covers exposed muzzle threads on rifle and pistol barrels to prevent dings, cross-threading, and grime buildup whenever you’re not running a muzzle device or suppressor. Options come in common thread pitches like 1/2×28 and 5/8×24 in a range of materials, with knurled or textured finishes for easy removal by hand. Need something different on the end of your barrel?
