Experimental Romanian Paratrooper PKM

This video from Shot Show 2026 provides an in-depth look at new and surplus firearms from Zastava Arms USA. Key highlights include discussions on M70 parts kits with differing receiver thicknesses, the historical significance of trench art on surplus rifles, and the functionality of Zastava's grenade launching spigots. The review also covers the M57 surplus pistol, a new M90 configuration with a pinned and welded flash hider, a .300 Blackout M85 variant, and the highly anticipated semi-auto M84 (PKM). The information is presented by Ranko, a representative with deep knowledge of Zastava products and history.

This video provides an expert look at the semi-automatic Zastava M84 PKM, a firearm based on the Russian PKM design, chambered in 7.62x54R and featuring a heavy barrel. It also highlights the Zastava AK Suppressor, claimed to be the lightest and quietest in the U.S. based on Pew Science testing, with compatibility across several Zastava models. The firearm is currently awaiting ATF approval for the U.S. market.

This video provides a detailed comparison between the Soviet RPD and PKM machine guns. It highlights the RPD's rifle-like ergonomics and AK-inspired internals, contrasting it with the PKM's lighter feel due to stamped construction and its more powerful 7.62x54R caliber. Key differences in features like charging handles, barrel systems, and receiver construction are discussed.

This Q&A delves into the history and evolution of Finnish small arms, comparing iconic models like the Suomi KP/-31 to Soviet counterparts such as the PPSh-41, highlighting Finnish design superiority in quality and reliability. It covers early service rifles like the Berdan II, details the Suomi's features, and discusses Finnish Maxim machine guns. The discussion extends to modern Finnish firearms, including the RK 95 and the new Sako M23 AR platform, while also touching on Finnish culture and spirits.

The UK vz.59 Czech Universal Machine Gun features a unique pistol grip charging system and a push-through belt feed for 7.62x54R cartridges. While functional, its light weight and low profile result in significant recoil, making full-auto control difficult compared to heavier platforms like the PKM. Downward ejection of hot casings also presents a handling challenge.

This video provides an in-depth look at the Yugoslav M84, a variant of the Soviet PKM machine gun. It covers the historical context of its development, stemming from the need for a modern GPMG, and details its mechanical operation, including its open-bolt firing cycle, belt feed mechanism, and unique features like the hinged recoil spring guide. The review also touches upon its similarities to the AK platform, particularly in bolt design and receiver construction.

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.
