Late-Production Degtyarev PPD 34/38 at the Range

This review delves into the rare original DShK-38 Soviet heavy machine gun, highlighting its development from the DK and Shpagin's crucial rotary feed system. The video contrasts its 12.7x108mm caliber with the US .50 BMG and details its unique charging mechanisms and flapper-locking action. Despite slow WWII production, it became a ubiquitous post-war tank and allied weapon.

The PPD-40, designed by Vasily Degtyarev, was the first major Soviet submachine gun, initially influenced by the DP-27. Despite its accuracy and reliability, its complex, lathe-turned construction made it expensive. The PPD-40 saw significant development, notably adopting a drum magazine inspired by the Finnish Suomi M31, and was later replaced by the mass-producible PPSh-41.

The PTRS-41 is a Soviet semi-automatic anti-tank rifle, essentially a scaled-up SKS firing the powerful 14.5x114mm cartridge. It could penetrate 40mm of armor at 300 meters, making it effective against early WWII German tanks. Despite crude external wartime production, its internal mechanics are similar to the SKS, featuring a detachable barrel for transport.

The DS-39 was a Soviet attempt at a universal machine gun, designed to replace the Maxim. It featured an air-cooled barrel and a dual rate of fire, but suffered from critical design flaws like out-of-battery detonations and violent extraction. Despite its adoption in 1939 and use in the Winter War, it was produced in limited numbers and ultimately replaced by the SG-43 Goryunov.

The PTRD-41 was a simple, single-shot Soviet anti-tank rifle developed rapidly in 1941. Chambered in the powerful 14.5x114mm cartridge, it could penetrate significant armor at range. Its unique recoil-operated action ejected spent casings automatically, aiding in rapid firing. Despite its effectiveness, limitations like barrel life and firing signature prevented its use as a sniper rifle.

The RP-46 is a belt-fed conversion of the Soviet DP/DPM light machine gun, designed to bridge the gap between the RPD and heavier machine guns. It features a quick-change barrel, an adjustable gas system operated by a mallet, and unique cleaning rod storage within the bipod legs. Despite its 1946 adoption and service until 1961, original Soviet RP-46s are rare.

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.
