This video explains the historical origins and design rationale behind the AR-15/M16 forward assist. It details how the US Army's requirement for a manual bolt closure mechanism, stemming from their experience with reciprocating charging handles, led to its inclusion, despite initial design intentions by Eugene Stoner and Colt. The speaker highlights the debate over its necessity, noting that forcing a fouled bolt can worsen jams.

Quick Summary

The forward assist on AR-15 and M16 rifles was added due to US Army requirements for manually closing the bolt on fouled actions, a need arising from their familiarity with reciprocating charging handles, despite designer Eugene Stoner's original intent.

Frequently Asked Questions

Did Eugene Stoner design the forward assist for the AR-15?

No, Eugene Stoner and Colt did not originally intend for the AR-15 to have a forward assist. The US Army's requirements, stemming from their experience with reciprocating charging handles, led to its eventual inclusion.

Why did the US Army want a forward assist on the M16?

The Army, accustomed to reciprocating charging handles, needed a mechanism to manually ensure the bolt closed fully into battery, especially if the rifle became fouled or dirty during operation.

What is the main argument against using the forward assist?

The primary argument is that forcing a round into battery on a dirty or fouled rifle can create a worse jam, potentially making the firearm inoperable until cleared, sometimes requiring a 'mortaring' technique.

What is the AR-15's charging handle type?

The AR-15 platform features a non-reciprocating charging handle. This design choice meant that a separate mechanism, the forward assist, was considered necessary by the Army for manual bolt closure.
