Slow Motion: M1912 Steyr Hahn

This video details the history and technical evolution of the B&T MP9/TP9, tracing its origins from a Steyr project. Key improvements by B&T include the addition of a stock and the adoption of a standard Picatinny rail. The firearm's unique rotating barrel, short recoil operation, and innovative bolt manipulation feature using a 9mm cartridge are highlighted.

The Steyr AUG (StG 77) is a revolutionary bullpup rifle featuring an integrated 1.5x optic and extensive polymer construction. Its progressive trigger allows for both semi-automatic and full-automatic fire with a single trigger pull. The rifle also boasts a quick-change barrel system and a fully polymer fire control group.

The Steyr ACR was a 1990s bullpup rifle developed for a US military program, notable for its polymer construction and unique flechette ammunition. Firing needle-like projectiles at an extreme 4,800 fps, it featured an open-bolt action and a distinctive ring primer for reliable ignition. While innovative, it represented a departure from conventional firearm design.

Aimpoint is releasing the COA optic as a standalone product in 2024, expanding beyond its previous Glock-exclusive integration. The optic will be available for integration with major manufacturers like Springfield Armory and Smith & Wesson, with aftermarket support for custom A-cuts on existing firearms. New rifle mounts are also planned for release, making the COA a versatile option for various platforms.

The Steyr Scout rifle adheres to Jeff Cooper's strict criteria for a scout rifle: under 1 meter in length and weighing under 3 kg (6.6 lbs) for maximum handiness. It's designed for practical effectiveness, capable of taking down a 200 kg (450 lb) animal at ranges up to 300-400 yards/meters within the shooter's skill. The forward-mounted Leupold optic is a key feature for this versatile rifle.

The Samostril Netsch was a bizarre early 1920s Czech prototype automatic rifle designed by Jozef Netsch. It featured a unique gas trap system where a forward-moving barrel shroud cycled the action. Intended as a rifle-machine gun intermediate, it competed in 1923 military trials but failed after limited firing. Despite its failure, 25 were contracted, with many surviving in the VHU Prague collection.

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.
