The FN PS90 magazine is an FN Herstal factory-produced magazine for the FN PS90 and FN P90 platforms. The magazine is designed to hold and feed 50 rounds of 5.7x28mm ammunition. Its impact-resistant, semi-transparent polymer body is incapable of succumbing to rust or other corrosion.

This top-mounted longitudinal magazine fits flush with the frame of the firearm and features a spiral feed ramp that rotates cartridges 90 degrees prior to loading them into the chamber. As is expected, this magazine benefits from the performance and reliability that has become characteristic of all FN Herstal factory products and is guaranteed to fit and function in your firearm.

No matter if you own a PS90 or an AR57 these factory magazines by FN should be your first choice for feeding your firearm 5.7 ammunition. There may be other alternatives, but only one has the FN logo that is recognized world wide for quality and performance.
