Negev 7: Israeli Scales up to a 7.62 NATO Machine Gun

The Negev 7 is an Israeli 7.62 NATO chambered light machine gun, a modernized evolution of the 5.56mm Negev. Key features include a stable receiver-mounted optic rail, a quick-change barrel system, and a long-stroke gas piston operation. Unlike its predecessor, it is belt-fed only, utilizing 100 or 125-round boxes, and retains a rare semi-automatic fire mode for zeroing.

The IMI Galatz, a Galil-based DMR chambered in 7.62 NATO, was introduced in 1983 and imported to the US as a semi-auto rifle. It features a heavy 23-inch barrel, a substantial muzzle brake, and a unique left-offset scope mount with a spring-loaded bipod. The standard Nimrod 6x40 scope offers BDC out to 800 meters, and the rifle achieves approximately 1.5 MOA accuracy, balancing precision with a higher volume of fire.

The Negev LMG, developed by IMI (now IWI), was Israel's answer to reliability issues with the FN Minimi (M249 SAW). It features a unique dual-feed system engineered for magazine reliability, a three-position gas regulator for adjustable rate of fire (700-1000 RPM), and a fixed optics rail for consistent zero. Its internal mechanics utilize a short-stroke gas piston and dual recoil springs for improved controllability.

This review compares the Czech UK vz.59 and the Yugoslav M84 PKM, both chambered in 7.62x54mmR. While similar in weight and ergonomics, the PKM demonstrates significantly better controllability in full-auto fire, allowing for a maintained sight picture, unlike the UK vz.59 which transmits more recoil. The PKM's full-auto potential is highlighted as superior, whereas the UK vz.59 is noted as potentially more pleasant in semi-automatic for civilian use.

The PKM is presented as a highly effective and surprisingly lightweight General Purpose Machine Gun (GPMG), weighing only 16 pounds. Its design, often described as an 'upside-down AKM,' features an inverted gas system and a barrel more in line with the stock for improved control. Operating from an open bolt, it fires the powerful 7.62x54R cartridge and boasts a quick-change barrel system and a sturdy bipod.

This review covers the Russian PKM machine gun, highlighting its reliability and simplicity, making it suitable for combat use. The video details its AK-style operating system and field stripping process. It also features a review of the affordable Huntertown Guardian 22 suppressor on a GSG 1911 pistol.

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.
