RP-46: The Rarely Seen Belt-Fed Degtyarev

The DP-27, also known as the "Record Player" due to its pan magazine, was a Soviet light machine gun developed by Vasily Degtyarev. It utilized a unique 47-round pan magazine to reliably feed the rimmed 7.62x54mmR cartridge. While initially full-auto only with a grip safety, combat experience led to the modernized DPM variant.

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.

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.

This video provides a detailed look at the DP-27 Degtyaryov Machine Gun, a Soviet light machine gun. It demonstrates the loading process for the 47-round pan magazine using 7.62mm blanks and showcases assembly, including a muzzle device and receiver markings indicating a 1932 production date. The demonstration includes live fire from both prone and standing positions, highlighting the weapon's historical significance and operational aspects.

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.

This review of the Chinese Type 56 RPD details its development as a squad-level LMG designed for the 7.62x39mm cartridge, offering a lighter alternative to full-power rifle cartridges. It highlights the RPD's belt-fed system using 50-round metallic belts in a drum carrier and discusses variations in belt designs from Russia, Hungary, and China. The video also covers external features like the 'clubfoot' stock, internal mechanics including the long-stroke gas piston and flapper locking system, and its service history as a predecessor to the RPK.

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.
