SilencerCo
A barrel thread protector is one of those small accessories that pays for itself the first time you need it. The SilencerCo Black Nitride Steel Thread Protector for Firearm Barrels is a simple, durable solution for preserving the muzzle threads on your rifle or pistol while you're waiting on suppressor paperwork, transporting your firearm, or simply running without a can attached. Protecting threads from dust, debris, and damage is critical—cross-threaded suppressor mounts are expensive and frustrating mistakes that a few dollars' worth of prevention eliminates entirely.
Made from steel with a black nitride finish, this protector is built to handle repeated installation and removal without stripping or corroding. It's offered in two standard thread sizes to match the most common muzzle patterns in the US: .578 X 28 (found on most .45 ACP handguns) and 1/2 X 28 (the de facto standard across most centerfire rifles and many pistols). Installation is straightforward—hand-tighten onto your barrel threads without forcing, and you're done. No tools needed, no permanent modifications.
Whether you're a suppressor owner between Form 4 approvals, a hunter who runs suppressors seasonally, or someone who simply values clean threads and a professional-looking muzzle, this is the kind of thing you'll wonder how you ever did without. It's the small-dollar insurance that keeps your threaded barrel in ready condition for whenever your suppressor is ready to mount.

Hand-tighten the protector onto your barrel's muzzle threads. Do not force it or cross-thread—simply twist it on carefully until snug.
