Frequently Asked Questions

What was the Colt 602's significance in firearm history?

The Colt 602 was a pivotal transitional rifle, bridging the gap between the early Colt 601 and the standardized XM16E1/M16A1. It represented a significant step in the AR-15's evolution towards becoming America's primary battle rifle.

What are the key differences between the Colt 601 and the Colt 602?

The Colt 602 featured black plastic furniture instead of the Colt 601's green fiberglass, a three-prong flash hider replacing the duckbill, and lacked a forward assist, which was added to later models like the XM16E1.

Why did the US military initially resist the AR-15 platform?

The military establishment favored the heavier, traditional M14 and viewed the lightweight AR-15 as a 'toy.' They were hesitant to adopt a rifle firing a smaller caliber bullet, despite its potential advantages in weight and handling.

What caused early M16 reliability issues in Vietnam?

Early issues stemmed from a change in gunpowder that increased fouling and the absence of chrome-lined chambers, leading to corrosion and extraction problems in humid environments. The rifle was also misleadingly marketed as 'self-cleaning'.
