OCL OPS/AE/OC Black Thread Protector - Durable & Reliable

The Otter Creek Labs OCL OPS/AE/OC black thread protector is a rugged muzzle device accessory built to protect your barrel threads when you're not running a suppressor. Made from 17-4 stainless steel and finished in black nitride, this knurled protector threads on securely and handles the wear and tear of field use without compromising the integrity of your muzzle threads.

Compatibility is straightforward: this protector fits Ops Inc 12 model muzzle devices, AEM5 suppressors, and OCM5 pattern devices. It also works with OTB, OTB-MB/FH, PTB, and MWA 1-piece adapters, so if you're running one of those platforms, you've got a ready solution for thread protection during transport, storage, or when swapping suppressors.

The knurled design gives you a positive grip for hand-tight removal and installation—no special tools needed. The black nitride finish resists corrosion and blends cleanly with most modern rifle builds. Whether you're a suppressor user managing multiple cans or protecting threads on a host gun between shoots, this is the kind of simple, durable accessory that belongs in your maintenance kit.
