DShK-38: The Soviet Monster .50 Cal HMG

This review explores a semi-automatic conversion of the Soviet DShKM heavy machine gun, chambered in .50 BMG by Midwest Metal Creations. Originally developed as an anti-aircraft weapon, the DShKM's design history is traced from its 1920s origins through Shpagin's improvements. The conversion retains the distinctive Shpagin feed system and unique charging method while adapting to a closed-bolt, striker-fired semi-auto operation for US accessibility.

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 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 takes viewers to Grand Power in Slovakia to showcase their impressive 12.7x108mm DShK. The description emphasizes the sheer power of this caliber, stating it makes .50 BMG seem like a training round. It also includes links to the creators' recommended gear, their full shows on CarbonTV, and their merchandise store.

This video explores the Ukrainian adaptation of the Soviet DShK heavy machine gun for infantry support roles. Modifications include a significant muzzle brake for recoil control, bipods, and shoulder stocks to enhance portability and suitability for trench warfare. The DShK's effectiveness against vehicles and hardened targets at long ranges is highlighted, with comparisons to historical US weapon experiments.

The RP-46 is a rare Soviet belt-fed adaptation of the DPM machine gun, notable for its unique bolt-handle actuated feed system. This mechanism uses a drop-in adapter with a cammed track and hooks to pull cartridges from the belt. Despite its innovative design, the RP-46 is seldom encountered today, highlighting its historical rarity.

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.
