Timber Creek Outdoors TCCN Castle Nut - AR-15 Black Anodized

The Timber Creek Outdoors TCCN Castle Nut delivers precision-machined reliability for AR-15 buffer tube installations. This black anodized aluminum component ensures proper buffer tube retention while providing the clean, professional appearance that discerning builders demand.

What Makes This Different

Unlike standard castle nuts that rely on basic staking methods, the TCCN features precision-cut castellations that provide multiple secure staking points. The Type III hard anodized finish resists wear and corrosion better than standard mil-spec coatings. Each castle nut undergoes CNC machining to ensure consistent thread engagement and proper torque retention across multiple installations.

Key Features

• Type III hard anodized black finish for superior corrosion resistance
• Precision CNC-machined from 6061-T6 aluminum billet
• Standard AR-15/M4 carbine buffer tube threading (1.148"-16 TPI)
• Multiple castellations provide secure staking options
• Consistent torque specifications prevent over-tightening damage
• Compatible with all mil-spec and commercial buffer tubes
• Made in USA with lifetime manufacturer warranty

Installation torque specifications remain consistent at 35-40 foot-pounds, ensuring proper buffer tube retention without thread damage. The precision machining eliminates the binding issues common with lower-quality castle nuts during installation. Professional armorers and home builders alike appreciate the consistent thread engagement that prevents cross-threading during assembly.
