Apex Tactical Specialties Thread Protector Features The Apex Tactical Thread Protector is machined from stainless steel with a natural finish that matches Apex barrels though it installs just as well on other brands of threaded 1/2x28 barrels. It is the same protector that ships standard with Apex Grade threaded barrels so shooters get genuine factory quality hardware. A rubber O-ring included with the protector cushions the muzzle crown and helps keep the unit from loosening under recoil or handling. This simple addition prevents unwanted wear and galling on exposed threads whenever a suppressor or compensator is not mounted. The knurled exterior gives a firm gripping surface making it easy to hand tighten or remove the protector without tools. Each package includes one thread protector sized to fit any standard 1/2x28 pistol barrel. Beyond protecting the threads the protector gives a pistol a neat finished appearance when no muzzle device is installed. Shooters who swap between a bare barrel and a suppressor setup will appreciate having a dependable easy to use protector on hand.
