Ross 1912 Cadet: Straight Pull .22 Rimfire Training Rifle

This expert-level entry from Forgotten Weapons' Ian McCollum details the Ross 1912 Cadet .22 rifle. Production estimates place the total between 13,000 and 17,000 units, with production ending in 1917. McCollum highlights that auto-ejection of spent casings is not a feature but a symptom of worn locking surfaces, necessitating professional gunsmithing.

This YouTube video, titled 'Just In! Swiss K31 Carbine Straight Pull Rifles,' focuses on showcasing a specific firearm. While no transcript is available, the title clearly indicates the main subject is the Swiss K31 carbine, highlighting its straight-pull action. The description provides links to the creator's social media profiles on Facebook, Instagram, and Twitter, suggesting a platform for further engagement and content sharing related to firearms.

The Whitney Wolverine is a .22 caliber semi-automatic pistol from the 1950s, notable for its Atomic Age design featuring a tubular shroud instead of a traditional slide. Its mechanical components are steel, housed within an aluminum frame, and it utilizes a unique tapered magazine with a heel release. An attempt to reintroduce it in 2002 with a polymer lower was unsuccessful.

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.

This video examines the Webley .22 Target Model Mk IV Revolver. The description highlights its history as a factory .22 rimfire target model introduced in 1932, featuring a 6-inch barrel and adjustable sights. It notes that while mechanically similar to the .38 MkIV, its firing pin was adapted for rimfire cartridges. Production ceased in 1967, and these revolvers are considered relatively rare today. The video also promotes Headstamp Publishing books and the "Forgotten Weapons" content platform.

The KK-Mpi-69 is an East German .22 rimfire training rifle based on the AKM design, featuring a simple blowback action instead of gas operation. It was used for pre-military youth training, offering realistic handling with a standard AK receiver and safety selector, including a full-auto position. Approximately 50,000 were produced between 1970 and 1975.

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.
