FN P90 - Variants

Variants

P90 TR

The P90 TR (Triple Rail) model, also known as the "flat-top," was introduced in late 1999. It features a receiver-mounted triple MIL-STD-1913 (Picatinny) rail interface system, or "Triple Rail," for mounting accessories. There is one full-length accessory rail integrated into the top of the receiver, and two rail stumps are included on the sides of the receiver. The top rail will accept various optical sights with no tools or additional mounting hardware required, and the side rails serve to mount secondary accessories, such as tactical lights or laser aiming devices.

P90 USG

The P90 USG (United States Government) model is similar to the standard P90, except the reflex sight housing is aluminium, and the sight has a revised reticle. The black reticle consists of a tiny dot inside of a small ring, which is joined by three posts that glow red in low light conditions due to tritium-illumination. The USG reflex sight can be removed and replaced with a special MIL-STD-1913 (Picatinny) rail mount for attaching a different sight.

P90 Laserex models

The P90 LV (Laser Visible) and P90 IR (InfraRed) models, both of which were introduced in late 1995, have an integrated laser sight manufactured by Laserex Technologies in Australia. The P90 LV model projects a 8 mW visible laser intended to be used as a low-light shooting aid or for dissuasive effect, while the P90 IR model projects a 4.5 mW infrared laser that can only be seen with night vision equipment. Both laser systems are compact, consisting of a small, flat panel integrated into the front end of the weapon's frame.

The Laserex P90 laser systems have a weight of 131 g (0.29 lb), and they are activated by means of a green pressure switch located on the underside of the weapon's pistol grip. The lasers can be configured for three different internal settings: Off – disabled to prevent accidental activation, Training – low intensity for eye safety and extended battery life in training, or Combat – high intensity for maximum visibility. The Laserex P90 laser systems have a battery life of 250 hours when used on the Training setting, or a life of 50 hours when used on the Combat setting.
