A stainless thread protector from Christensen Arms in 5/8-24, the standard thread pitch for .30-caliber and larger rifle muzzles. A thread protector is one of those small parts that is easy to overlook until you need it: exposed muzzle threads collect dirt and get dinged, and damaged threads can cause a brake or suppressor to sit out of alignment, which at best hurts accuracy and at worst is unsafe. Stainless matches most modern barrel finishes and resists corrosion.

Cheap insurance for an expensive barrel, and worth keeping a spare of.
