The WClose Quarter Battle Receiver (CQBR) is a replacement upper receiver for the M4A1 Carbine, developed by the US Navy. The CQBR features a barrel 10.3 in (262 mm) in length. This shorter barrel makes the weapon significantly more compact, which makes it easier to use in and around vehicles and in tight confined spaces. Special units such as commandos boarding ships and bodyguards for senior officers have found such shortened weapons very useful and use the CQBR.

The complete CQBR-equipped carbine has been type-classified by the US Navy as the Mk 18 Mod 0, or the Mk 18 Mod 1 with a sightless gas block and full-length accessory rail kit.

Insurgency[]


The Mk18 is a carbine featured in Insurgency.

It is exclusive to the Security Forces. It has a 30 round magazine, high recoil, and select full-automatic fire mode. Its compact size allows it to have the close-range versatility of a sub-machine gun, while retaining the firepower of a carbine.

However, due to its compactness and light weight, the Mk18 also has higher recoil than the full-sized M16A4 and cannot mount a M203 grenade launcher. Furthermore, unlike the sub-machine guns, the Mk18 has obstructive iron sights and an obstructive front sight with mounted optics.
