The Klärig Engineering "Protection Nut" protects the outher threadings and the "teeth" of the Klärig Engineering Borelock Brakes, when beeing used without suppressor.
Because of the very hard surface treatment of our brakes basically unneccesary, but because of many requests we offer them additionally.
But take care, that it does not loosen while shooting, otherwise the threadings will get damaged because of barrel vibrations.

The Nut is 100% Made in Germany, is made from special Tool Steel, and has the same surface treatment as our brakes (Surface Hardened and Oxidized)
Extremely corrosion and wear resistent.
