The FN P90 is my favorite PDW type firearm. It is a futuristic looking bullpup design which has actually been around since the 80's. This gun was ahead of it's time, featuring fully ambidextrous controls. It even ejects spent cases straight down so it is no problem to shoot from the left or right shoulder.
The early P90's came with an integrated optic. The one I have is the tritium illuminated version which features a black reticle and glows orange when viewed in low or no light.
The gun is fed from a magazine which loads on the top of the gun and holds 50 rounds of 5.7x28mm ammo. This is the same ammo used by the FN Five-Seven pistol.
This gun has been featured in many television shows, movies and video games. It is no wonder why. This little gun is awesome and super fun to shoot. The recoil is practically nothing so you can shoot fast and maintain accuracy.
