|Description: Bushmaster Firearms International, LLC is a manufacturer and distributor of guns which is based in Madison, North Carolina. Bushmaster's firearms are typically offered in a 5.56 NATO (223) chambering with forged aircraft-grade (7075-T6) aluminum receivers. Most Bushmaster barrels are 4150 steel, offered in 1:9 twist rate, and chrome-lined to increase durability. Some barrels are available with 1:7 rifling, on special order. Stainless steel or chrome molybdenum barrels are available on certain models.
Originally marketed for police and the military, Bushmaster later changed its unique hybrid version AR-15/M-16 to the standard Colt / Armalite design. The First Generation rifles were chambered for the 5.56mm round. Bushmaster First Generation rifles are very rare and are collectibles.
In late January 2008 Bushmaster signed a licensing deal with Magpul, granting Bushmaster the rights to produce and distribute Magpul's Masada rifle, renamed the Bushmaster ACR. In 2010, Bushmaster made the ACR available to the civilian market.
