Complimentary Installation Option:
At no additional cost, we offer complimentary installation of the XF50 receiver. If selected, we will professionally transfer all factory components—including the barrel, muzzle device, charging assembly, and all internals—from the original FN PS90 upper to the new XF50 Tri-Rail receiver. This ensures perfect fit and function using all OEM parts.
If you do not select the installation option, you will receive both the factory-assembled PS90 and the XF50 Tri-Rail receiver separately.
Important Note:
FFL required for shipment. Dealer license must be provided after order placement.
Build the ultimate PS90 platform with the strength and precision of the XF50 Tri-Rail receiver—now with optional professional assembly included.
