Strike Industries Tribus Enhanced Castle Nut & End Plate - Blue

The Strike Industries Tribus Enhanced Castle Nut & End Plate delivers superior retention and installation convenience compared to standard mil-spec components. This precision-machined upgrade features an integrated end plate design that eliminates the need for staking while providing multiple attachment points for tactical accessories.

What Makes This Different

The Tribus system incorporates Strike Industries' proprietary retention mechanism that maintains zero movement under heavy recoil without requiring permanent staking. Unlike traditional castle nuts that rely on staking for security, this enhanced design uses mechanical retention features machined into both the nut and end plate. The integrated construction reduces parts count while increasing reliability and simplifying installation for both professional armorers and home builders.

Key Features

• Integrated castle nut and end plate eliminates staking requirement
• Machined from 7075-T6 aluminum with Type III hard coat anodizing
• Multiple QD sling swivel attachment points for tactical flexibility
• Proprietary retention system prevents loosening under recoil
• Compatible with all mil-spec AR-15 buffer tubes and extensions
• Blue anodized finish matches Strike Industries aesthetic
• Tool-free installation with standard castle nut wrench

Field testing demonstrates consistent lockup across thousands of rounds in both semi-automatic and full-auto applications. The enhanced end plate provides solid mounting points for single-point and two-point sling configurations without compromising structural integrity. Weather resistance testing shows the hard coat anodizing maintains finish integrity through extended exposure to moisture, salt spray, and temperature cycling typical of duty environments.
