The Bushmaster M4 is a semi-automatic or select-fire carbine manufactured by Bushmaster Firearms International, modeled on the AR-15. It is one of the Bushmaster XM15 line of rifles and carbines.
The M4 Type Carbine is a copy of the Colt M4 carbine. The semi-automatic is marketed to the U.S. civilian market in compliance with the National Firearms Act. An assault rifle variant can be ordered by military or law enforcement organizations with three-round burst or fully automatic capability.
The rifle's caliber is .223 Remington/5.56×45mm NATO, and the barrel is hard chrome lined in both the bore and chamber. Unlike the current Colt M4 Carbine which features a 4-position telescopic , the Bushmaster has a 6-position stock. It is compatible with most standard AR-15 parts, and has the ability to accept all AR-15/M16 type STANAG magazines.
All variants of the rifle are available in either M4A2 and M4A3 configurations; the difference being the M4A3 has a removable carry handle allowing access to a Picatinny rail for mounting accessories.
The standard M4 Type Carbine features a permanently fixed "Izzy" flash suppressor attached to a 14.5 in (370 mm) barrel which brings the barrel to a total length of 16 in (410 mm). Bushmaster also produces the Patrolman's Carbine variant which features the more common removable "bird cage" flash suppressor, attached to a 16 in (410 mm) barrel bringing the total barrel length to 17.5 in (440 mm). Both of these comply with current U.S. federal law which states a minimum 16 in (410 mm) barrel for a rifle. There is also a military M4 Type Carbine which comes with a 14.5 in (370 mm) barrel and a removable "bird cage" flash suppressor. The 6.8mm SPC Rifle only comes with a 16 in (410 mm) barrel and a removable "Izzy" flash suppressor.
