The CS Predator (designated XM2 Predator) is a 5.56×45mm NATO, gas-operated long stroke gas piston, magazine-fed assault rifle developed in the Osean Federation during the 1980s. Its design is based on a Bushmaster ACR, with a flash hider of a M4. It was constructed as a need for a medium-range long barrel assault rifle to complement current M4 carbines and M16A4s.

The Predator is extensively used by the Osean Defense Forces and their allies, with decisions to largely replace the M16 rifle in Osean Army and Osean Marine Corps (OMC) combat units as a primary infantry weapon and service rifle. The Predator has been adopted by many countries, mainly allies of Osea as a standard assault rifle for their regular infantry units.

Since its adoption in 1998, the Predator has gone through many modifications. The XM2A1 and XM2A3 are the only upgrades of the Predator. The new variants strengthed the barrel, a selective fire including a 3-round burst and fulll auto fire, the SOPMOD, and an accessory kit containing optical attachments.

In April 2022, the Osean Army selected the SIG MCX Spear, designated the XM7, as the winner of the Next Generation Squad Weapon Program to replace the M16/M4/XM2.


The CS Predator is used for medium to short engagements, where the M4's short barrel would not be very effective as the Predator's long barrel. It has been a compact, light, customizable and accurate weapon. Though the Predator is not effective as the M4 in close quarters combat, due to its larger size and its longer barrel.

The Predator has a relatively low recoil, posing high damage and rate of fire. It is capable of long fully automatic fire, and is fitted with a 30-round magazine. ts high rate of fire makes it a good choice for intense firefights, while still possessing enough accuracy and damage to be reasonably effective at longer ranges.

The XM2A3 variant can fire 7.62×51mm NATO rounds in a 20-round magazine, but this ability was almost never used.
