Masterpiece Arms Data Card Holder (Mounts to Full Size BA Chassis Only)

The Masterpiece Arms Data Card Holder is a precision-engineered accessory designed for long-range shooters and precision rifle builders who demand organized, field-accessible ballistic reference data. Whether you're dialing elevation for distance shooting, recording environmental conditions, or tracking load development notes, this data card holder mounts directly to your full-size BA (Masterpiece Arms) chassis for real-time access without breaking position. It bridges the gap between your scope and your firing solution, keeping critical information within arm's reach during competition, hunting, or range sessions.

Built to integrate seamlessly with full-size BA chassis systems, the Masterpiece Arms Data Card Holder features a low-profile mounting design that clears optics and accessories while securing your data card at optimal viewing angle. The compact profile—measuring just 3 by 0.5 by 4.5 inches and weighing only 0.09 pounds—adds negligible weight or balance shift to your precision rifle platform. Its secure retention mechanism protects your data card from movement or loss during recoil, vibration, or field transitions, while the design allows quick card swaps when switching ammunition or environmental conditions. The holder accommodates standard index cards or ballistic data sheets, making it adaptable to any shooting discipline.

Precision rifle enthusiasts, competition shooters, and long-range hunters benefit most from this mounting solution, particularly those running MasterPiece Arms chassis systems where OEM integration eliminates fitment guesswork. Installation is straightforward for users familiar with chassis-based rifle builds, mounting directly to the existing rail or receiver interface without modifications. This accessory is compatible exclusively with full-size BA chassis platforms—verify your chassis designation before purchase to ensure proper fit and function on your precision system.
