This entry delves into the history and necessity of the AR-15 forward assist, a feature debated since its inception. Expert Ian McCollum explains the original 'slick side' design, the military's push for a bolt-closing device, and the various prototypes and testing that led to the plunger-style assist becoming standard on Army rifles. It highlights the differing perspectives between Colt and Springfield Armory, and Eugene Stoner's own reservations about the device's utility.

Quick Summary

The AR-15 forward assist, a plunger-style mechanism, was added to the M16A1 rifle at the U.S. Army's insistence, despite designer Eugene Stoner's reservations. It was intended to manually close the bolt, with Colt's design proving superior in adverse condition testing over alternatives like Springfield Armory's modified charging handle.

Frequently Asked Questions

What was the original design of the AR-15 regarding the forward assist?

The original AR-15, designed by Eugene Stoner, was a 'slick side' rifle. This meant it lacked both a forward assist and a brass deflector, a design choice that reflected its initial intended role and user base before broader military adoption.

Why did the U.S. Army insist on adding a forward assist to the AR-15/M16?

The U.S. Army pushed for the forward assist primarily for standardization and perceived operational benefits. They cited psychological advantages for soldiers and potential functional needs in adverse conditions, despite initial opposition from the Air Force and the rifle's designer.

What were the main competing designs for the AR-15 forward assist?

Two primary designs emerged: Colt proposed a plunger-style device, while Springfield Armory developed a solution using a modified charging handle that could push the bolt carrier forward. Both aimed to fulfill the Army's requirement for a manual bolt-closing mechanism.

Did Eugene Stoner believe the forward assist was necessary?

No, Eugene Stoner, the original designer of the AR-15, believed the forward assist was largely unnecessary. He reportedly favored the Springfield Armory design mainly because it would be easier to remove later if deemed superfluous.
