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.[3] 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 M601''' (Colt Model 601) is an early AR-15–pattern 5.56×45mm/.223 rifle produced by Colt after it acquired the AR-15 design from ArmaLite. It is best known for its “slick-side” receiver (no forward assist), early-pattern features (including triangular handguards and distinctive early furniture), and its role as a direct predecessor to the later [[M16]] family. In ''Military Conflict: Vietnam'', the tables above list its in-game values pulled directly from the weapon script.


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.

A commonly cited technical difference between early Colt AR-15 production runs is barrel twist rate: early rifles used a **1:14** twist, while later rifles shifted to **1:12** to better stabilize the standard 55-grain ball (M193) and tracer projectiles across a wider range of conditions. These incremental changes—along with later durability and maintenance-focused updates seen on Vietnam-era M16 variants—reflect how the platform evolved from early AR-15 production into the standardized U.S. service rifles of the Vietnam War period.

The M601 (Colt Model 601) is an early AR-15–pattern 5.56×45mm/.223 rifle produced by Colt after it acquired the AR-15 design from ArmaLite. It is best known for its “slick-side” receiver (no forward assist), early-pattern features (including triangular handguards and distinctive early furniture), and its role as a direct predecessor to the later M16 family. In Military Conflict: Vietnam, the tables above list its in-game values pulled directly from the weapon script.

HISTORY

After ArmaLite sold the AR-15 rights to Colt in 1959, Colt’s first major production model was the **Model 601**, which entered serial production around late 1959 and continued into the early 1960s. Early 601/602 rifles closely followed the original ArmaLite pattern and were often marked “Colt ArmaLite AR-15” rather than “M16,” reflecting the transitional period before the M16 designation became standard. The Model 601 is generally distinguished by its early “slick-side” upper (no forward assist) and a variety of early-production external details that were refined on later M16-family rifles.

A commonly cited technical difference between early Colt AR-15 production runs is barrel twist rate: early rifles used a **1:14** twist, while later rifles shifted to **1:12** to better stabilize the standard 55-grain ball (M193) and tracer projectiles across a wider range of conditions. These incremental changes—along with later durability and maintenance-focused updates seen on Vietnam-era M16 variants—reflect how the platform evolved from early AR-15 production into the standardized U.S. service rifles of the Vietnam War period.
