North Korean Type 73: A PK That Uses Both Mags and Belts

The PKM, a Soviet-designed machine gun by Mikhail Kalashnikov, fires the 7.62x54R round and features a unique inverted AK-47-like gas system. It has variants like the PKT for vehicles and remains a globally used military firearm. The video highlights its history, design, and modern relevance.

The Zastava M84, a licensed PKM variant, is lauded for its extreme reliability and durability, even enduring 500-round bursts without erosion. Its design allows for easy conversion between tripod and bipod configurations. Modifications like folding stocks and Picatinny rails enhance its modern utility, making it a versatile GPMG with historical significance and combat-proven performance.

This YouTube video features Demolition Ranch conducting an accuracy test on a PKM machine gun, specifically highlighting its full-auto capabilities. The title and description suggest a focus on the firearm's performance and results, likely appealing to viewers interested in military surplus, heavy machine guns, and shooting dynamics. The use of hashtags like #fullautofriday and the mention of #civtac (civilian tactical) indicate a blend of enthusiast content and potentially civilian-legal aspects of such firearms.

This video provides a direct comparison between the PKM and M60 machine guns, demonstrating their destructive power on a Smart car. It highlights the visual impact and damage caused by sustained fire from both iconic weapons, offering insights into their operational characteristics and the effectiveness of their respective calibers in a destructive test scenario.

This video tests the ballistic penetration of various firearms, from handguns to .50 BMG rifles, against a flipped Range Rover. Smaller calibers like 9mm and .45 ACP failed to penetrate the undercarriage, while rifle rounds like 7.62x39mm and 5.56mm showed some penetration. The M60 and PKM machine guns inflicted significant damage, and the .50 BMG round easily destroyed the vehicle's gas tank and chassis.

This video showcases the formidable Russian DShK (Dushka) heavy machine gun, originally chambered in 12.7x108mm but modified to fire .50 BMG. The review highlights its immense power through tests against a vault door and ballistic dummies, demonstrating significant penetration and destructive capability. The content also includes a humorous Halloween skit and a sponsorship segment for home security.

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.
