Unique British Crankfire .58 Morse Manual Machine Gun

The LMG-25, Switzerland's first modern light machine gun, features a unique toggle-locking system developed by Adolf Furrer. Chambered in 7.5x55mm Swiss, it offers select-fire capability and a 30-round magazine compatible with the Stgw 57. A notable feature is the Advanced Primer Ignition (API) system, which reduces felt recoil and rate of fire by igniting the primer while parts are still moving forward.

The Stamm-Saurer Model 1916 is a rare experimental Swiss light machine gun designed by Hans Stamm. This air-cooled prototype, one of two built, retains features from water-cooled designs for manufacturing ease. It utilizes a short-recoil action, fires the 7.5x55mm GP11 cartridge from a 20-round magazine, and incorporates a unique out-of-battery safety mechanism.

This video details the legal distinctions and technical differences between registered bolt and registered receiver Uzi conversions for NFA compliance. Registered receivers are generally preferred due to their flexibility, allowing standard full-auto bolts and easier caliber conversions, unlike registered bolts which are caliber-specific and have replacement limitations. The discussion highlights the historical context of Uzi conversions and the ATF regulations that shaped their design.

The Marlin Model 1917 is a licensed copy of the Colt Model 1895/1914, itself an evolution of the original Colt 'Potato Digger'. It features a unique gas-operated system using a swinging lever mechanism, distinct from typical gas pistons. This lever, when activated by gas tapped from the barrel, cycles the action, earning the 'Potato Digger' nickname due to its violent movement potentially digging into the ground.

This video showcases the classic Reising M50 machine gun, a firearm designed in the late 1930s and likely manufactured around 1940, making it over 80 years old. The description highlights its historical significance and recommends the book "The Many Firearm Designs of Eugene Raising" by David Albert for further information. An Amazon link to the book is provided.

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.

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.
