Headstamp's Second Book! Thorneycroft to SA80: British Bullpup Firearms

This expert-level entry details the British L1A1 Self-Loading Rifle (SLR), specifically serial number one, as explained by firearms expert Jonathan Ferguson of the Royal Armouries. It covers the rifle's historical context, unique British modifications like 'sand cuts' and an enlarged magazine catch, its service life from 1957 to 1991, and specific markings for identification. The L1A1 SLR represents a significant evolution in British small arms development.

The L85A3 represents a significant ergonomic and structural modernization of the British Army's SA80 rifle, primarily featuring a new Heckler & Koch-designed slimline M-LOK handguard and an FDE Cerakote finish. While internal components largely remain A2 specification, improvements like electron beam welding enhance receiver rigidity. The optic is typically the Elcan Specter OS4, often paired with a Shield CQB red dot.

This video provides an in-depth look at the Rexim Favor SMG, featuring expert Jonathan Ferguson. The analysis covers its unusual internal mechanics, design features, and historical context, including company drama and the influence of designer Favier. The video also explores its unexpected afterlife in science fiction, referencing its appearance in Star Wars and Alien. The Royal Armouries museum context is highlighted, with links to their collection and support pages.

The Enfield Revolver, formally the 'Pistol, Revolver, Breech-loading, .476 inch', was a complex and ultimately unsuccessful British military sidearm. Despite passing initial trials for accuracy and durability, its unique sliding cylinder extraction mechanism proved problematic for loading and unloading. Introduced in 1879, it was superseded by the Webley Mk.I in 1887, marking the end of Enfield's revolver development.

This video explores the rare British SREM-1 bullpup sniper rifle, developed by the Armament Design Department in 1944. It features a unique pump-action mechanism integrated into the pistol grip and a 'downhill' bolt travel for improved sight alignment. Despite its innovative design, the SREM-1 was ultimately cancelled in favor of conventional sniper rifles and emerging self-loading designs.

This video features firearms expert Jonathan Ferguson examining the Sterling SAR80, a rifle developed as a legally distinct but ultimately derivative of the AR-18. The discussion will likely cover its design, historical context, and attempts at commercial viability, comparing it to its predecessor, the LAR.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
