FN P90

The FN P90 is a submachine gun produced by the Belgian Fabrique Nationale de Herstal to replace the pistol-caliber submachineguns.


The submachine FN P-90 has several features that go beyond its unconventional design. Actually the proposal of the FN Herstal launched this little gun when the market was to provide a self-defense weapon (PDW concept Personeal Defense Weapon), compact enough to be carried by crew members with land and air vehicles, and had a power equivalent to fire an assault rifle at distances of 150–200 meters.

In order to gather these requirements in a submachine, the FN had to develop not only a new weapon, but also a new caliber, bringing back the ammo-style" bottle "found in rifles, submachine to the compact. The new size is 5.7x28mm, which is very small, being slightly larger than 9mm ammunition, in terms of length, but with an initial speed at the muzzle of the P-90, which has 11 ½ inches, 850 m/sec. Speed equivalent to a rifle at 7.62x51mm. Given this aspect in all, still, the fact of being fully jacketed bullet, the result is a very effective

performance piercing . Certainly, this penetrating ability, and the small diameter of the projectile stopping power of ammunition should not be very significant, because when there transfixed excessive, there will be little energy transfer to the target, thereby reducing stopping power. Still speaking in the ballistic characteristics of this new ammunition, the trajectory of the bullet is extremely tense, and after 300 meters, the drop of the trajectory of the bullet is extremely sharp .

The FN has chosen BullPup configuration to achieve to make its new compact weapon. In this configuration the gun mechanism is mounted within the stock optimizing the internal space of the gun, and limiting the length of the P-90 in a mere 50 cm. The operating system is the blowback with the bolt closed, feature, such that decreases the problems of using the P-90 in terms of dirt or merging. The finish of the P-90 is in high-impact plastic, and the barrel and firing mechanism, the only metal parts being the P-90 a very light gun. Other notable advance in the P-90 is its reflex sighting system which is already standard. With this aim, the soldier has an electronic point that is projected on the lens of sight, making it easier to target even in low visibility conditions. Actually there is a way of night sights, specifically, available on target system and allows the use of P-90 normally under these conditions . New versions of the P-90, as the P-90 TR (Triple Rail), show that the FN has not stopped thinking about how to improve your project by placing picatini rails on top and sides of the P-90, facilitating the mounting of accessories as laser sights and flashlights into the gun. For the civilian market North America and Europe, there is a carbine version known as PS-90, and whose pipe is larger, with 16 inches in length and only semi-automatic operation .

With the P-90, FN is a high- tech and high reliability with a single direct competitor in the market that is the modern HK MP-7

nterface system, or "Triple Rail". Originally, there was one full-length rail on the top of the base and two rail stumps on the sides of a slightly redesigned upper receiver. This original version was phased out, and is no longer in production. The newer TR models, initially introduced as TAC (for 'tactical') use the standard upper receiver, but with a full-length rail in place of the standard sight. The top rail itself has emergency iron sights contained just under the mounting area. In both cases of the TR, the side rails serve to mount accessories such as laser aiming devices or flashlights, while the integrated top rail will accept various optics with no tools or additional mounting hardware required.

  • P90 USG

The P90 USG (United States Government) variant is similar to the standard P90 with the exception of a revised optic system, developed based on input from the United States Secret Service and other government agencies. The aluminium sight uses a non-magnified black reticle that does not require ambient light.

  • P90 Laserex models

The P90 LV (Laser Visible) and P90 LIR (Laser Infrared) models add an integrated visible laser sight or infrared sight, respectively. They were introduced in late 1995. Both units are manufactured by the Australian company Laserex Technologies. The laser's power switch is a green button located under the trigger grip. The lasers have three internal settings: "off" – to prevent accidental activation, "low-intensity" – for combat training and extended battery life, and "high-intensity" – for maximum visibility.
