This video provides an in-depth look at the BSA-28P Automatic Rifle, a post-war British experimental firearm. Jonathan Ferguson, Keeper of Firearms & Artillery at the Royal Armouries, details its design, operating mechanism, and historical context within Britain's search for a new service rifle. The entry highlights the rifle's unique features, its competition with other designs like the EM-1 and EM-2, and the reasons for its eventual failure in trials, including reliability issues and design complexity.

Quick Summary

The BSA-28P Automatic Rifle, designed in 1948 by BSA, was Britain's attempt to find a new service rifle. Chambered in .280 caliber, it featured a unique sideways tilting bolt and a gas system inspired by the M1 Garand. Despite its innovative design, it failed military trials due to critical reliability issues, including an out-of-battery detonation, leading to its rejection.

Frequently Asked Questions

What was the BSA-28P Automatic Rifle?

The BSA-28P was a post-war experimental automatic rifle designed in 1948 by Claude Perry and Roger Wackrow for the Birmingham Small Arms Company (BSA) as part of Britain's search for a new service rifle. It competed against designs like the EM-1 and EM-2.

What caliber was the BSA-28P chambered in?

The BSA-28P was chambered in the .280 (7mm Mk 1Z) intermediate cartridge. This caliber, combined with its select-fire capability, technically classifies it as an assault rifle by modern definitions.

Why did the BSA-28P fail to be adopted by the British military?

The BSA-28P failed primarily due to significant reliability issues encountered during military trials. A critical failure involved an out-of-battery detonation during a sand test, leading to its rejection in favor of other designs like the EM-2.

What were some unique features of the BSA-28P?

The BSA-28P featured a unique sideways tilting bolt head for unlocking, a gas-operated system inspired by the M1 Garand, and a built-in spigot grenade launcher. It also had a rate-of-fire reducer to manage its high natural cyclic rate.
