Strike Industries Tribus Enhanced Castle Nut & End Plate Set

The Strike Industries Tribus Enhanced Castle Nut & End Plate transforms standard AR-15 buffer tube installations with precision-engineered components that eliminate common staking and loosening issues. This matched set provides superior torque retention and streamlined installation compared to mil-spec alternatives.

What Makes This Different

The Tribus system features Strike Industries' proprietary anti-rotation design that maintains consistent torque without traditional staking methods. The enhanced castle nut incorporates multiple retention points that distribute stress evenly across the receiver extension threads. This eliminates the need for aggressive staking that can damage components while providing 40% greater holding power than standard castle nuts.

Key Features

• Anti-rotation castle nut design eliminates staking requirements
• Precision-machined 7075-T6 aluminum construction
• Low-profile end plate accommodates QD sling attachments
• Mil-spec threading compatible with all AR-15/AR-10 platforms
• Anodized black finish resists corrosion and wear
• Integrated wrench flats for secure installation
• Beveled edges prevent snagging on gear and clothing

Field testing demonstrates the Tribus system maintains zero movement under rapid-fire conditions and extreme temperature cycling. The enhanced end plate's reinforced QD socket supports heavy-duty sling systems without deformation. Competition shooters report consistent point of impact after thousands of rounds, while tactical users appreciate the snag-free profile during close-quarters operations.
