Yankee Hill Machine Co. .308 Rifle Thread Protector 5/8x24 – .920 OD

This Yankee Hill Machine thread protector caps the muzzle threads on .308 rifles threaded 5/8x24, preventing thread damage during transport, storage, or when shooting without a muzzle device. The .920-inch outer diameter matches common bull and heavy-profile barrels, maintaining a clean, flush appearance at the muzzle.

Machined steel construction with a black oxide finish provides corrosion resistance and durability. Hand-tight installation is sufficient for range use; apply anti-seize compound to threads before installation to prevent galling and simplify removal when mounting suppressors or muzzle brakes. Check headspace if removing and reinstalling muzzle devices frequently.
