When combined with the synthetic six-position telescoping stock, you get a carbine that weighs in at just 6.7 pounds unloaded. The inclusion of a muzzle brake is intended to reduce recoil and muzzle rise. The chrome lining serves to protect the barrel and the chamber from rust and corrosion as well as giving them higher resistance to wear. The Bushmaster M4A3 Patrolman carbine features a 16-inch, chrome-lined barrel (1:9-inch twist rate) and an overall length of 32.5 inches. As noted, the configuration available here is the M4A3, which includes a removable carry handle that, when removed, offers access to an integrated MIL-STD 1919 rail. It is also worth noting that the Patrolman is available in two different configurations: the M4A2 and the M4A3. Based on the M4-type carbines that the company is famous for, each Patrolman is built with an increased barrel length to make them BATFE compliant. The Bushmaster M4A3 Patrolman carbine is one of the company's most popular civilian versions of the M4.

Today, the M4 is swiftly replacing most M16s still in service with the United States Army. The major difference is the shortened barrel characteristic of the M4, which typically measures 14.5 inches. Though the M4 and the M16 have 80 percent parts commonality, some key differences do exist. Though very similar to the M16, the M4 is both shorter and lighter than the M16 and is equipped with a six-position telescoping stock. The M4 carbine is a part of a family of firearms that can be traced back to M16 rifle, which was originally based on Eugene Stoner's AR-15. Today, Bushmaster still makes its home in Madison, North Carolina, though its production facility is in Ilion, New York.

Now, nearly 40 years later, Bushmaster is known for its line of firearms that provide the military, law enforcement agencies and civilians with AR-15-patterned firearms known for their quality, reliability, accuracy, durability and value. That company was Bushmaster Firearms International LLC. In 1973, a company was founded in Madison, North Carolina with an aim to provide a line of high-quality AR-15-patterned rifles and carbines.
