This review delves into the Glock 18, a selective-fire machine pistol based on the Glock 17, known for its appearance in video games. It highlights the unique selector switch, its history with counter-terrorism and special forces, and the challenges of controlling its high cyclic rate during full-auto fire. The video also touches upon its internal mechanics, perpetual Gen 3 configuration, legal requirements (SOT), and its niche application despite its versatility.

The Polish PM63 Rak is reviewed as a machine pistol with significant ergonomic and operational flaws. Its reciprocating slide ejects debris, and the sights are difficult to use due to movement. The progressive trigger makes semi-automatic fire challenging, often leading to unintended full-auto bursts. Compared to other machine pistols like the Skorpion, the PM63 is ranked lower due to poor handling and distracting mechanics.

This video features a review of the Glock 18 machine pistol and a converted Glock 17. The creators explore whether these fully automatic firearms are as unwieldy as commonly perceived. The description also includes links to a related blog post, another YouTube video for further technical details, merchandise, and social media channels. Affiliate links are disclosed for support. The video emphasizes its documentary, educational, and entertainment purpose, adhering to NFA rules and disclaiming liability for misuse.

This review delves into the Vz61 Skorpion, a compact Czechoslovakian PDW developed in the late 1950s. It highlights the Skorpion's unique rate-reducing mechanism for controllable full-auto fire and its historical use by various state and non-state actors. The review also covers its pop culture appearances and the challenges of adapting it for the US market.

The VZ 61 Skorpion is a compact, full-auto machine pistol designed for second-line troops. Despite its small size, it offers controllable full-auto fire due to its light .32 ACP recoil and a unique rate reducer mechanism. The firearm features a folding wire stock and fires from a closed bolt for improved accuracy, making it a historically significant and fun-to-shoot NFA item.

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.
