Legal for you to own
Now for those looking to own one the FN PS90 is a semi-automatic only sport version designed for the civilian market. It has olive drab synthetic stock body and an MC-10-80 reflex sight identical to that used on the standard P90. Reflex sight can be removed and replaced with a special top rail to allow you to use third party optics. The barrel has 8 right-hand grooves, a rifled length of 376 mm and comes with a fixed "birdcage" type flash suppressor. The overall length of the PS90 is 667 mm. The receiver assembly is drilled and tapped to accept accessory Picatinny rails on either side. It accepts the standard P90 50-round magazines, but is sold only with a 10 or 30-round magazine depending on local and state regulations. The PS90 weighs 2.9 kg empty and 3.4 kg with a fully loaded 50-round magazine.
