The Stamm-Saurer Model 1907 was a rare Swiss straight-pull bolt-action rifle developed by Hans Stamm for Saurer to compete for military contracts. Despite its high quality and innovative features like a unique rear sight and integrated cleaning rod, it was rejected by the Swiss military. The rifle competed against the Schmidt-Rubin K11 and G11, ultimately losing due to existing institutional knowledge of the Schmidt-Rubin and Saurer's refusal to license production.

TFB TV's James Reeves and Kaya highlight the top 5 long guns from IWA & EnforceTac 2026. The list features innovative designs like the Schmeisser DRS-9 PCC, the compact Serengeti S-Mini shotgun, the robust Zastava M20 machine gun, Sako's versatile AR platform rifles, and the aesthetically striking Walther RS3 straight-pull bullpup rifle, showcasing a range of modern firearm advancements.

The WF-51 was a Swiss intermediate-cartridge rifle developed by Adolf Furrer at Waffenfabrik Bern, inspired by the German FG-42. It featured a unique tipping bolt mechanism and was chambered in 7.5x38mm, with 35 units produced for trials. Although it did not enter service, its development influenced later Swiss firearms before the adoption of the SIG Stgw 57.

This video provides a detailed look at the Swiss Schmidt-Rubin M1889 rifle, chambered in 7.5x53.5mm GP90. The presenter aims to debunk common misconceptions, particularly regarding the ammunition's "smokeless" properties, arguing that books describing it as "semi-smokeless" are incorrect. The video highlights the historical significance of this Swiss firearm and its specific caliber, offering expert insight for enthusiasts.

The Swiss 1897 Kadettengewehr is a single-shot training rifle based on the Schmidt-Rubin 1889/96 action. It features a unique dual-calibrated rear sight designed for both standard GP90 and reduced cadet loads, matching ballistics to ensure the cadet load at the muzzle equals the standard load at 100 meters. This rifle served the Swiss Cadet Corps from its production in 1898 until the early 1950s.

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.
