SA80 History: The First L85 Mockups (Sterling and Stoner)

Published on May 5, 2017
Duration: 12:54

This video explores the early mockups and prototypes of the British SA80 rifle, focusing on the Sterling and Stoner-based bullpup conversions. It details the design considerations, including caliber choices and configuration decisions, that led to the final L85 design. The prototypes demonstrate the feasibility of the bullpup concept using existing rifle platforms.

Quick Summary

The British SA80 rifle project originated from dissatisfaction with the 7.62 NATO FAL's power, leading to research into smaller calibers. Early prototypes were bullpup conversions of Sterling AR-180 and Stoner 63 rifles, demonstrating the feasibility of the chosen configuration.

Frequently Asked Questions

What were the early prototypes for the British SA80 rifle based on?

The early proof-of-concept prototypes for the SA80 were constructed by converting existing firearms into bullpup configurations. Specifically, RSAF Enfield used a Sterling AR-180 receiver for one functional prototype and a Stoner 63 for another, which served as a basis for the Light Support Weapon variant.

Why did the British military pursue the SA80 project?

Following the adoption of the 7.62 NATO FAL (SLR) in 1957, the British military felt it was too powerful. This dissatisfaction spurred early research into smaller calibers and a replacement rifle, ultimately leading to the development of the SA80 program.

What design choices were made for the SA80 rifle?

Designers evaluated various configurations, ultimately selecting a bullpup design with a straight-line stock. This configuration was chosen to minimize muzzle climb and maintain a compact overall profile for the rifle.

What was the Sterling 'Annoyance' Project?

The Sterling 'Annoyance' Project involved Sterling building a non-functional bullpup AR-180 mockup. This was a protest against the government allegedly copying their AR-180 design for the SA80 project without proper compensation or recognition.
