Swedish Paratrooper Prototype: AK Fm/57

This video from Forgotten Weapons details the complex journey of Lithuanian rifles following WWII. Due to successive Soviet and German occupations, these arms were scattered, ending up in various national arsenals, with partisans, and eventually dispersed globally to regions like China, Vietnam, and Africa as part of post-war arms caches. The expert analysis highlights the geopolitical impact on small arms distribution.

The URZ, a rare Czech prototype, showcases a unique roller-delayed blowback action distinct from common HK designs. It features an innovative dual-purpose drum and belt box feed system with mechanical cartridge feeding via cam tracks in the bolt carrier. Only nine examples were ever manufactured, highlighting its experimental nature and historical significance in Cold War firearms development.

The Little Tom is highlighted as the world's first Double Action Only (DAO) automatic pistol, featuring a unique bi-directional magazine loading system. Its barrel disassembly involves pushing it back to release an oval lug from a dovetail slot. The internal mechanism demonstrates a specific trigger bar and hammer interaction for DAO operation.

This video details the French Trials FN CAL, a prototype rifle tested by the French military in the 1970s. It highlights the rifle's unique four-position selector switch and its specialized rifle grenade launching capability, featuring an adjustable rear stop and integrated folding sights. The modified 25-round magazine with a viewing window is also examined.

The LMG-25 is a unique Swiss toggle-locked light machine gun developed by Waffenfabrik Bern. It features a three-position fire selector (Safe, Semi-auto, Full-auto) and an innovative toggle-lock mechanism that articulates during the charging cycle. A key feature is its advanced primer ignition mode, designed to reduce recoil by igniting the primer while the bolt is still moving forward.

This video reviews "The World's Assault Rifles," a book described as essential for any firearm enthusiast's library. The author highlights its broad scope and deep detail, making it a foundational reference for modern military small arms. The video also includes links to the publisher for purchasing the book and to the creator's Patreon and merchandise store.

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.
