<Li> SME Ordnance, Malaysia </Li> <Li> Sarsılmaz, Turkey </Li> <P> The M4 was developed and produced for the United States government by Colt Firearms, which had an exclusive contract to produce the M4 family of weapons through 2011 . However, a number of other manufacturers offer M4 - like firearms . Colt previously held a U.S. trademark on the term "M4". Many manufacturers have production firearms that are essentially identical to a military M4, but with a 16" barrel . The Bushmaster M4 Type Carbine is a popular example . Civilian models are sometimes colloquially referred to as "M4gery" (/ ɛmˈfɔːrdʒəri / em - FOR - jər - ee, a portmanteau of "M4" and "forgery"). Colt had maintained that it retains sole rights to the M4 name and design . Other manufacturers had long maintained that Colt had been overstating its rights, and that "M4" had now become a generic term for a shortened AR - 15 . In April 2004, Colt filed a lawsuit against Heckler & Koch and Bushmaster Firearms, claiming acts of trademark infringement, trade dress infringement, trademark dilution, false designation of origin, false advertising, patent infringement, unfair competition, and deceptive trade practices . Heckler & Koch later settled out of court, changing one product's name from "HK M4" to "HK416". However, on December 8, 2005, a District court judge in Maine granted a summary judgment in favor of Bushmaster Firearms, dismissing all of Colt's claims except for false advertising . On the latter claim, Colt could not recover monetary damages . The court also ruled that "M4" was now a generic name, and that Colt's trademark should be revoked . </P> <Ul> <Li> Afghanistan: Used only by Afghan Army commandos .
