AR-15 Extreme Duty Wide Castle Nut For Car/M4 Buffer Tube (Matte Rainbow PVD Coated)

Description

This AR-15 Extreme Duty Wide Castle Nut is engineered for US Made production standards, providing a robust interface between the upper receiver and the buffer tube. Constructed from Steel, this component utilizes the Gen 3 design, which offers an enhanced profile for improved structural integrity compared to standard Mil-spec nuts. The Matte Rainbow PVD Coated finish provides corrosion resistance and a distinct visual profile, featuring an iridescent surface that shifts through pastel hues of pink, purple, blue, and yellow.

• Material: Steel construction for maximum durability.
• Fit: Compatible with Mil-spec and Commercial Buffer Tube.
• Design: Wide profile with Gen 3 geometry for enhanced strength.
• Finish: Matte Rainbow PVD Coated for aesthetic appeal and protection.

Designed for experienced builders, this nut ensures a secure lockup for the castle nut retainer pin. The wide design allows for better engagement with the Buffer Tube internal threads and the takedown pin, reducing the risk of stripping or loosening under recoil. The Matte Rainbow PVD Coated surface is not only visually striking but also serves as a durable barrier against the elements and wear.

Installation requires standard AR-15 tools. Ensure your buffer tube is compatible with Mil-spec or commercial standards before purchase. This part is a direct replacement for worn or stripped Castle Nut, restoring proper function to your upper receiver assembly. The US Made origin guarantees adherence to specific manufacturing tolerances and quality control measures.
