HISTORY

Colt's first two models produced after the acquisition of the rifle from ArmaLite were the 601 and 602, and these rifles were in many ways clones of the original ArmaLite rifle (in fact, these rifles were often found stamped Colt ArmaLite AR-15, Property of the U.S. Government caliber .223, with no reference to them being M16s).

The 601 and 602 are virtually identical to the later M16 rifle without the forward-assist. Like the later M16 rifle their charging handle was re-located from under the carrying handle like AR-10 to the rear of the receiver. They were equipped with triangular fore-stocks and occasionally green or brown furniture. Their front sight had a more triangular shape. They had flat lower receivers without raised surfaces around the magazine well. Their bolt hold open device lacked a raised lower engagement surface and had a slanted and serrated surface that had to be engaged with a bare thumb, index finger, or thumb nail because of the lack of this surface. Their fire-selector was also changed from upward = safe, backward = semi-auto and forward = full-auto, to the now familiar forward = safe, upward = semi-auto, and backward = full-auto of the M16 rifle.

The only major difference between the 601 and 602 is the switch from the original four grooves, right-hand 1:14-inch (1:355.6 mm or 64 calibers) rifling twist rate to the more common four grooves, right-hand 1:12-inch (1:304.8 mm or 54.8 calibers) twist. This was done as the original 1:14-inch twist rate to just stabilize the 55 grain bullet used in the 5.56 Ball M193 cartridge under unfavorable conditions could induce too much yaw and due to the resulting excessive in flight bullet destabilization become inaccurate. The one turn in 12 inches increased accuracy and was optimized to adequately stabilize the M193 ball and longer M196 tracer bullets.
