A SilencerCo AC1360 9mm Luger thread protector is essential insurance for your suppressor-ready barrel when you're not running a can. This black steel 1/2"-28 TPI protector threads onto your 9mm barrel to guard the critical muzzle threads from dust, dirt, and debris—keeping them clean and crisp so your suppressor seats perfectly every time. Whether you're in the waiting period for ATF paperwork or simply transporting your AR-platform pistol or rifle, a quality thread protector prevents the cross-threading and thread damage that can turn a simple suppressor installation into a gunsmith visit.
The 1/2"-28 TPI (threads per inch) standard is the most common pitch for 9mm Luger barrels in the US market, making this protector compatible with most factory and aftermarket 9mm barrels built to that specification. Installation is straightforward: hand-thread it on gently and firmly—no tools required, no guesswork. The hard-wearing black steel construction resists corrosion and won't rattle loose in your range bag or truck bed.
SilencerCo's thread protectors are a no-brainer accessory for any serious suppressor owner. They're affordable, durable, and they solve a real problem: stripped or fouled threads are invisible until you need them to work, and by then it's too late. Keep one on your 9mm until your suppressor arrives, then rotate it to your next project. It's the kind of small detail that separates thoughtful shooters from everyone else.

The SilencerCo AC1360 is threaded 1/2"-28 TPI, which is the standard pitch for most US-made 9mm Luger barrels.

If you're unsure of your barrel's thread pitch, check the barrel marking, your rifle's documentation, or ask your gunsmith.
Yes—that's exactly what thread protectors are for. Wear it during transport and storage while your ATF Form 1 or commercial suppressor registration is pending, then swap it for your actual suppressor once it arrives.
No. The AC1360 hand-threads onto your barrel. Simply align it carefully and twist it on by hand until snug. Avoid over-tightening or forcing it, which can damage the threads you're trying to protect.
Yes, the AC1360 is designed for AR-platform builds. It will work on any AR-chambered 9mm with 1/2"-28 muzzle threads.
