Note: The castle nut was meant to be installed using an adjustable or fixed spanner wrench. A traditional AR multitool or wrench can work but may cause damage to the castle nut. First position will be lost. Recommended torque value 40 inch pounds.
Due to dimensional tolerances between some manufacturer's receiver extension collar lengths and differing amount of true threads on various buffer tubes, some may experience difficulties installing.
