Defending Freedom Around the Globe. Founded in 1973, Bushmaster is a firearms manufacturer based in North Carolina and now owned by the Freedom Group. These are the same folks that own Remington, Marlin, DPMS -- among others. The XM-15 M4-A3 Heavy Barrel Carbine is a Colt / ArmaLite pattern rifle, which means it is completely interchangeable with standard AR-15 parts.

This has not always been the case as Bushmaster originally began in the early '70's by using steel uppers with an AK-47 style gas system. While these early rifles are now rare and extremely collectible, Bushmaster quickly abandoned the design and instead adopted a standard AR-15 operating platform. The model XM-15 is Bushmaster's designation for their AR-15 rifle.

At the heart of the design is a direct gas impingement system. Gas is tapped from the barrel as the bullet passes by the port located above the rifle's front sight base. The gas then rushes into the port and down a gas tube located above the barrel and into the upper receiver. From there, the gas tube funnels into the bolt carrier. This gas system unlocks the bolt and begins the cycling process, but only after the bullet has exited the barrel.

Direct impingement has several advantages over gas piston systems. For semi- automatic rifles with a barrel length of 16" or greater, impingement AR-15s are lighter, easier to free float the barrel, and much less expensive to manufacture.

A 6- position collapsible stock allows the shooter to adjust length of pull to their personal preference, while the carbine length handguard provides steady handling. The buffer tube dimensions are those of the smaller diameter commercial spec. However, everything else about the Bushmaster is mil- spec.

The XM-15's bolt has been magnetic particle inspected, shot peened and pressure tested to ensure that it's structurally sound and will not fail. Similarly, the gas key has been properly staked to the bolt carrier.

The heavy profile 16.1" 4150 chrome moly steel barrel is then chrome lined to make it less susceptible to fouling, reduce corrosion and enhance feeding. The 1:9" twist rate is fast enough to stabilize heavy bullets like the 69gr match rounds, while still capable of accurately firing standard 55gr ball ammo.

The Bushmaster XM-15 is chambered for 5.56 NATO cartridges , which allows you to safely fire both full power 5.56 or lower powered .223 rounds interchangeably without adjustment to the gas system. M4 feed ramps ensure proper feeding of ammunition to help reduce malfunction rates, even during rapid fire.

Since this is an M4 rifle, it is interesting to note that the trademark infringement lawsuit Colt filed against Bushmaster and Heckler & Koch was thrown out by the United States Court of Appeals, who ruled that both company's may use the "M4" designation since it's a generic term.

Both upper and lower receivers are forged from durable, lightweight aircraft grade 7075-T6 aluminum. Due to the fact the bolt locks into a steel extension on the barrel and not the receiver, the Bushmaster XM-15 can easily use such lightweight materials without sacrificing structural integrity.

The receiver surfaces are then hard coat anodized and dry film lubed per military spec to provide wear and corrosion resistance. The rifle weighs in at 6.7 pounds and includes one 30- round magazine. All steel parts wear a mil- spec manganese phosphate finish, including the barrel. Build quality is excellent and there is virtually no play between the upper and lower receiver.

A detachable A3 rear carry is easily removable for the mounting of optics on the Picatinny receiver rail. Unlike the rear sight, the A2 front sight post is fixed. In the rare event a round fails to go into battery, the rifle is equipped with a forward assist. Similarly, a spring loaded receiver dust cover is designed to keep out dirt and other debris from entering the action, but instantly opens on the first shot.

For repair, the Bushmaster is backed by a 1- year warranty. Overall, the Bushmaster XM-15 M4-A3 Heavy Barrel Carbine is an affordable, well built AR-15 designed for year of reliable service.
