The Pistollo 77 is a unique SMG/PCC originating from the Czech Republic, designed to accept standard Glock magazines. It features a distinctive front-mounted charging handle and an under-handguard bolt release. The firearm utilizes a lever-delayed blowback operating system, contributing to a high-quality shooting experience, further enhanced by its trigger.

This video showcases the CZ-38 pistol from 1939, demonstrating its operation with .380 ACP ammunition. It features live-fire sequences from various angles, including a first-person perspective engaging steel targets. Slow-motion footage highlights the pistol's cycling and slide lock.

Polenar Tactical announces a significant sponsorship with Sellier & Bellot ammunition, a brand they have used and trusted for years. This partnership is highlighted as a major achievement, especially for them being based outside the US in Slovenia. The video announces an upcoming trip to the Czech Republic for a factory tour and further discussions on their collaboration, promising "kickass video content." Support links for their store and Patreon are provided.

This video provides an in-depth look at the Sellier & Bellot ammunition manufacturing process in the Czech Republic, showcasing the creation of 5.56x45mm rifle rounds. It details the journey from raw brass to finished cartridges, highlighting critical steps like cup punching, annealing, case drawing, bullet production, and automated loading. The presentation emphasizes the high level of automation and quality control employed in their modern facility.

This video demonstrates the VZ-58 rifle, specifically its reliability with a 75-round drum magazine in cold weather tactical drills. It highlights the rifle's performance during sustained fire and showcases various configurations and accessories available from Zahal. The content emphasizes the VZ-58's robust nature and feeding reliability, even under demanding conditions.

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.
