This guide details the installation of the Strike Industries modular chassis system for the FN PS90, focusing on improving ergonomics. The process involves disassembling the original PS90 stock and transferring internal components into the new chassis. While offering improved handling and accessory mounting options like a 1913 rail and M-Lock compatibility, it introduces a non-tool-less disassembly for the trigger pack compared to the original design.

Quick Summary

The Strike Industries modular chassis system for the FN PS90 enhances ergonomics by providing a more conventional grip, accessory mounting options via 1913 and M-Lock rails, and improved shootability. While it retains ambidextrous features, it trades the original's tool-less trigger pack disassembly for these ergonomic upgrades.
