This entry details the pre-production XL85 rifle and XL86 Light Support Weapon, precursors to the British SA80. It highlights their design evolution, including improvements to the magazine well and reliability enhancements through tighter tolerances. The political context surrounding their adoption, driven by the privatization of RSAF Enfield, is also discussed. Instruction is provided by Ian McCollum, demonstrating high expertise in firearm history and manufacturing.

This video demonstrates the terminal ballistics of the SA80 L86A1 Light Support Weapon firing a 5.56x45mm NATO round into a 10% ballistic gelatine block. It explains the principles of permanent cavity, temporary cavity, and penetration, using the gelatine block as a scientific standard to simulate human tissue. The description also touches on the history and design intent of the 5.56mm round as an intermediate rifle cartridge.

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.
