Frequently Asked Questions

What were the main technical changes in the M16A2 compared to the M16A1?

The M16A2 featured a 1:7 barrel twist for heavier NATO rounds, a 3-round burst fire mode, a reinforced receiver, a longer stock, a new pistol grip, round handguards, and a modified muzzle brake. It also included a cartridge case deflector.

Why was the barrel twist rate changed for the M16A2?

The barrel twist rate was increased from 1:12 (M16A1) to 1:7 for the M16A2 to properly stabilize the heavier 62-grain M855 NATO cartridge and the M856 tracer round, especially in cold weather conditions.

What was Eugene Stoner's opinion on the M16A2's design changes?

Eugene Stoner expressed skepticism, calling the 3-round burst 'ridiculous' and the complex sights unnecessary for combat. He felt the design compromises detracted from the original rifle's focus on lightweight portability and combat effectiveness.

What was the controversy surrounding the M16A2's 3-round burst feature?

The primary issue was the lack of a reset mechanism. If a shooter fired one round and released the trigger, the next pull would only fire the remaining two rounds of the burst, which was seen as a significant flaw.
