Forward Controls CNF – Castle Nut

The Forward Controls CNF (Castle Nut, Forward Controls) is a premium upgrade to the standard AR-15/M4 castle nut, engineered for precision, durability, and ease of installation. Unlike conventional castle nuts, the CNF is designed with extra staking notches and superior machining to ensure your receiver extension is secured under even the harshest conditions.

Key Features

• Precision Machined: Made from 4140 steel, heat treated, and finished in black nitride for exceptional strength and corrosion resistance.

• Improved Staking Design: Features 4 staking notches (instead of the usual 3), allowing more staking options and flexibility during assembly.

• Enhanced Security: Deep, well-defined notches make staking easier, providing a rock-solid lockup of the receiver extension.

• Mil-Spec Compatible: Works with AR-15, AR-10, and M4 platforms using standard receiver extensions.

• Professional Finish: Black nitride coating provides a sleek look and long-lasting protection against wear.

• Made in the USA: Forward Controls’ reputation for attention to detail and uncompromising quality comes through in every CNF.
