SA80 History: XL70 Series Final Prototypes (Individual Weapon and LSW)

This video details the history and development of the British SA80 carbine variants, focusing on the 1989 prototype, a 1994 experimental version, and the adopted L22A2. It highlights design choices driven by parts availability and the evolution of the carbine's features, including barrel length, gas systems, and handguards, culminating in the Heckler & Koch redesigned L22A2.

This video delves into the pre-production XL85 and XL86 variants of the British SA80, highlighting their development stages before official adoption. It details critical design changes like the magazine well and improvements for the Light Support Weapon (LSW) to address reliability and accuracy issues. The adoption of the SA80 is also contextualized within the political landscape of RSAF Enfield's privatization.

The Aly & Kaufman AKB-23 is a bullpup conversion kit for the Brownells BRN-180, designed to replicate the feel and ergonomics of the British SA80/L85 rifle. Utilizing the AR-180's mechanical lineage, the kit offers an affordable way to experience the bullpup platform. It features a milled aluminum lower and 3D-printed furniture, with assembly requiring integration of the BRN-180 upper. Performance is noted as reliable, providing an authentic handling experience.

The Aly & Kaufman AKB-23 is a bullpup conversion kit for the Brownells BRN-180, designed to emulate the British L85/SA80. It features a milled aluminum lower with an AR-15 fire control group, connected via a trigger transfer bar. The 3D-printed furniture mimics the L85's ergonomics, and range testing confirms it captures the rifle's feel and accepts SA80 magazines.

This video demonstrates the terminal ballistics of the SA80 L86A1 Light Support Weapon firing 5.56x45mm NATO ammunition into a 10% ballistic gelatine block. The content explains the scientific principles behind ballistic gel testing, including the formation of permanent and temporary cavities, and the importance of penetration depth. It details how gelatine simulates human tissue for wound track analysis and discusses the characteristics of the 5.56mm round, its origins with the AR-15/M16 platform, and its effectiveness when yawing. The description also provides a link to the Royal Armouries collection.

This video provides an in-depth look at the Electronic Individual Weapon 97 (EIW97), an experimental electronic variant of the SA80, presented by firearms expert Jonathan Ferguson. It details the system's programming, software, and operational capabilities, including its unique tailoring for individual soldiers and integration potential with future soldier systems. The EIW97 explored advanced concepts like electronic ignition and programmable fire control, influencing modern small arms development.

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.
