The Close 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, similar to the Colt Commando short-barreled M16 variants of the past. 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.
Its preliminary National Stock Number was 1005-LL-L99-5996; however, a complete CQBR-equipped carbine now has the NSN 1005-01-527-2288. The overall length of the upper receiver is 19.25 inches (489 mm). With the stock retracted, the overall length of the weapon is 26.75 inches (679.4 mm).
