The M605B (Colt Model 605B) is an early Colt CAR-15 “carbine” variant of the AR-15/M16 family chambered in 5.56×45mm/.223. It is best known for its shortened barrel configuration and a four-position fire control group that added a burst option compared to the simpler 605A. The Model 605B was produced in very limited numbers and did not see wide field adoption.
HISTORY
The Colt Model 605 was Colt’s first major attempt to produce a “carbine”-style AR-15/M16 by shortening the standard rifle while keeping the fixed stock and triangular handguards. Two primary versions were offered: the **Model 605A** with a three-position selector (Safe, Semi, Auto) and the **Model 605B** with a four-position selector (Safe, Semi, Burst, Auto).
To create the compact configuration, the barrel was cut down just past the front sight base, the bayonet lug was removed, and the flash hider was reattached, resulting in an overall length of roughly 34 inches. Contemporary references describe the 605/605B as being produced in very small quantities and note that it did not see wide military field use due to unreliable operation.
