Colt bought the manufacturing rights for the AR-15 from ArmiLite in 1959, and in 1960 offered the first Colt AR-15.. the model 601.

The only reason the Army was finally forced to consider the platform was the Air Force wouldn't stop asking for it, along with the inconvenient fact that 1,000 rifles had been sent to Vietnam for testing (Project Agile 1961) and reports back were outstanding. Thus began the story of the M16.

This is a highly authentic reproduction of this first model AR-15.

* Note on Twist Rates:

Eugene Stoner originally designed the AR-15 with a 1:14 twist barrel, firing a 55gr bullet (the only bullet used at the time). Today we have a range of bullets available - which is why we offer this Assembly in two different twist rates:

  • 1:14 is historically correct and ideal for 55gr bullets. The choice If you want the closest possible to the real thing and will only shoot this bullet weight.
