Improving Mosins: The Estonian M1935

This video focuses on a "Ski Trooper" variant of the Finnish M28 rifle, exploring "Adventures in Surplus." The description also promotes a Kickstarter campaign for a book titled "Forged in Snow," suggesting content related to historical firearms, winter warfare, or snowy environments. The M28 is a Mosin-Nagant variant, commonly chambered in 7.62x54mmR.

This video focuses on the iconic 1891 Mosin-Nagant rifle, a historical and widely produced military bolt-action firearm. The description highlights its official designation as the 3-line rifle M1891, its Russian nicknames 'Mosin's rifle' and 'mosinka', and its primary chambering in the 7.62×54mmR cartridge. The rifle's development timeline from 1882-1891 is mentioned, along with its extensive service in the Russian Empire and Soviet Union, and its continued use in various global conflicts. With over 37 million units produced, it stands as one of history's most mass-produced military bolt-action rifles.

The Russian Mosin-Nagant 1891 is a historically significant, long, and hefty bolt-action rifle chambered in 7.62x54mmR. While its cock-on-open action can be stiff and its trigger mushy, it offers a simple safety mechanism and decent ladder sights. Despite ergonomic quirks, it's considered an enjoyable rifle for hobbyist shooting, with recoil comparable to .30-06.

This video focuses on the Mosin-Nagant Model 1891/30, a significant military rifle known for its five-shot bolt-action design and internal magazine. Primarily chambered in the 7.62×54mmR cartridge, the 1891/30 is highlighted as the most produced variant, issued to Soviet infantry from 1930 to 1945. The description details key modifications from earlier Dragoon rifles, including flat rear sights marked in meters and a cylindrical receiver (often replacing the octagonal 'hex' receiver), and its common use as a sniper rifle in World War II. Collectors often favor earlier models with octagonal receivers.

This review details Finland's first standard sniper rifle, the m/27PH, a modified Mosin-Nagant. Despite its historical significance, the rifle is critically examined for its poorly designed, heavy Physika prismatic scope with extremely short eye relief. The review highlights the rifle's limited production, logistical issues, and eventual obsolescence in favor of captured Soviet rifles.

This expert-level overview details the Finnish M28 Mosin-Nagant, often called the 'Ski Trooper' rifle. Ian McCollum explains its development as an improvement over the Russian M91, its unique sourcing of parts from international surplus markets, and specific features like SIG barrels and double sling slots. The rifle's complex history, including Austro-Hungarian capture and Italian reparations, is meticulously traced.

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.
