The AR-15 forward assist, a feature insisted upon by the US Army, was a solution searching for a problem, with the Air Force and designer Eugene Stoner deeming it unnecessary. Despite initial opposition and the Air Force's preference for slick-side receivers, the Army's requirement for a manual bolt-closing device led to the adoption of the plunger-style assist, influenced by experiences with older service rifles. Testing showed Colt's plunger design performed better in adverse conditions than Springfield's alternative.

Quick Summary

Frequently Asked Questions

Why was the AR-15 forward assist added?

The US Army insisted on adding a forward assist to the AR-15 (M16) for standardization, citing psychological benefits for soldiers and potential needs for manually closing the bolt, despite designer Eugene Stoner and the Air Force believing it was unnecessary.

Did Eugene Stoner support the forward assist?

No, Eugene Stoner, the designer of the AR-15, agreed with the Air Force that the forward assist was unnecessary. He reportedly favored the Springfield design only because it might be easier to remove later.

Which forward assist design was ultimately adopted?

Colt's plunger-style forward assist was adopted by the US Army. It performed better than Springfield Armory's alternative in mud, dust, and cold weather testing, which was a key factor in the Army's decision.

What is a 'slick side' AR-15?

A 'slick side' AR-15 refers to an early receiver design that lacks both a forward assist button and a brass deflector. This was the original configuration adopted by the Air Force.
