Belton Repeating Flintlock: A Semiautomatic Rifle in 1785

The Belton Repeating Flintlock, designed in 1785, featured an innovative seven-shot magazine and a unique 'port fire' mechanism. This system allowed for sequential firing by sliding an ignited slow-burning fuse to successive touch holes, approximating a semi-automatic action without re-priming. The mechanism utilized secondary triggers to control the fuse's movement.

The Remington-Keene rifle, developed by John W. Keene and manufactured by Remington, was a tube-fed, bolt-action rifle chambered in .45-70 Government. Despite competing in the 1878 US military trials and seeing limited adoption by the Navy, it was commercially released in 1880. Its design features a unique bolt disassembly via a left-hand thread screw and a bottom-loading gate with an elevator mechanism.

This video revisits a classic brass-framed Henry rifle, highlighting its historical significance as an advanced firearm during the American Civil War compared to standard single-shot rifles. Hickok45 demonstrates the rifle's repeating action and loading process, noting that while original models used .44 rimfire, this modern reproduction is chambered in .44-40. The review showcases the rifle's rapid-fire capability on a private range.

This video explores an experimental Gras-Vetterli repeating rifle from the late 19th century, highlighting its unique Vetterli-style side loading gate and internal cartridge elevator. Despite its innovative design, it was ultimately rejected by the French military in favor of the Kropatschek system, illustrating the competitive landscape of repeating rifle development during that era.

The Colt Franklin, patented in 1884, was a unique bolt-action rifle chambered in .45-70, featuring a 9-round detachable hopper magazine designed by General William Franklin. Despite passing US Army and Navy trials with high reliability, only 50 were produced, and they were not adopted, likely due to concerns about the external magazine's durability. The rifle's design incorporated innovative feeding mechanisms and a bottom ejection system.

The Burgess 1878 Military Carbine, chambered in .45-70 Government, was an innovative lever-action rifle produced by Whitneyville Armory. It featured a unique and robust locking bar mechanism designed by Andrew Burgess, capable of handling high pressures. Despite its strength, the carbine faced production issues, including jamming in its side-loading variant and dangerous ammunition detonation problems with Remington UMC cartridges, which ultimately limited its military adoption and commercial success.

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.
