XF50

The XF50 System is a modular upgrade platform designed to enhance or fully replace the factory FN PS90/P90 upper. Whether you're upgrading an existing PS90 or building a P90-inspired firearm with minimal factory parts, the XF50 system delivers superior durability, improved modularity, and expanded compatibility.

Available in multiple configurations, including Slick Side and Tri-Rail, the XF50 Receiver provides a more rigid, stable platform for optics and accessories while maintaining full compatibility with factory and aftermarket components.
