Strike Industries Tribus Enhanced Castle Nut & End Plate - Red

The Strike Industries Tribus Enhanced Castle Nut & End Plate in red anodized finish transforms standard AR-15 buffer tube installations with precision-machined aluminum construction and integrated QD sling attachment points. This enhanced system replaces factory components with superior materials and expanded functionality for tactical applications.

What Makes This Different

Unlike standard castle nuts that require staking for proper retention, the Tribus system incorporates multiple locking mechanisms including precision threads and anti-rotation features. The integrated end plate eliminates the need for separate components while providing three QD sling mount positions at optimal angles. CNC-machined from 7075-T6 aluminum with Type III hard anodizing delivers corrosion resistance and wear protection that exceeds mil-spec requirements.

Key Features

• Three integrated QD sling attachment points positioned at 45-degree angles
• CNC-machined 7075-T6 aluminum construction with Type III hard anodizing
• Anti-rotation design eliminates need for staking or thread locker
• Compatible with mil-spec and commercial buffer tubes
• Wrench flats machined for standard armorer's tools
• Red anodized finish matches Strike Industries color coordination
• Single-piece end plate design reduces installation complexity

Field testing demonstrates reliable retention under rapid-fire conditions and extended training cycles. The QD mounting positions accommodate single-point, two-point, and transitional sling configurations without interference with charging handle operation or ejection port access. Hard anodized surfaces resist scratching from sling hardware and maintain color consistency through thousands of attachment cycles.
