Area 419 Hellfire Thread Protector Features The Area 419 Hellfire Thread Protector is machined from 6061-T6 aluminum specifically to shield the precision threads and taper surface of the Universal Adapter from dings debris and corrosion. Because the Universal Adapter s taper surface is critical to achieving a proper lockup with Area 419 s self timing brakes protecting it from damage helps preserve consistent return to zero performance over time. The thread protector installs quickly over the adapter whenever a brake is removed whether for cleaning storage or swapping between rifles. A wrench is included to assist with installation and removal when needed. Finished in black anodizing the protector resists wear from repeated handling and provides a clean finished look on an otherwise exposed muzzle device. At just 1 inch long and a tenth of a pound it adds negligible bulk to the end of the barrel while in place. This accessory is particularly useful for shooters who run multiple Universal Adapters across several rifles and want every adapter protected when its matching brake is not installed. For Area 419 Hellfire system owners looking to keep their Universal Adapter threads protected between uses this thread protector is available for sale at GrabAGun.
