This review of the Madsen Model 1945 submachine gun, presented by Ian McCollum of Forgotten Weapons from the Springfield Armory National Historic Site, highlights its unique design and historical context. The firearm is noted for its quality construction, pistol-like reciprocating slide, and use of Suomi magazines. Despite its advanced features for the time, its complexity and cost led to commercial failure, making it an extremely rare collector's item.

This review of the Glock 45 Gen 6, presented by 1ShotTV, highlights significant ergonomic improvements over previous generations, including a new grip texture, integrated palm swell, and beaver tail. While the pistol demonstrates excellent reliability with various ammunition types and impressive accuracy even at 100 yards, the reviewer expresses strong dissatisfaction with the new flat-faced trigger, deeming it heavy and mushy. Despite this drawback, the Gen 6 is considered by the reviewer to be the best out-of-the-box Glock released to date due to its enhanced frame.

This entry details the CZ 482 pistol, a precursor to the vz.52, highlighting its unique roller-locked mechanism and high-quality construction.

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.
