Dead Air DA424 Thread Protector 1/2x28 Steel Black

The Dead Air DA424 Thread Protector is a compact steel thread guard designed to shield the muzzle threads on host firearms when a suppressor is not in place. Precision-machined for a tight fit on 1/2x28 threaded rims, this protector is built for use with Dead Air rimfire adapters that mate to the Mask suppressor and similar rimfire setups.

The DA424 installs easily on any standard 1/2x28 threaded barrel, providing a low-profile cap that helps prevent damage, debris buildup, and thread wear during transport, storage, and routine handling. Its durable steel construction with a black finish delivers dependable corrosion resistance while adding virtually no length or weight to the host barrel. The protector covers approximately 0.4 inches of thread engagement, ensuring consistent protection without interfering with handguard clearance or other muzzle accessories.

Whether you run a dedicated rimfire suppressor platform or simply want to keep your host's threads in factory-new condition between suppressor mounts, the Dead Air DA424 is an inexpensive insurance policy against costly thread repair or replacement.
