Swedish K: The Carl Gustav m/45B and the Port Said

This video features a deep dive into two significant 9mm submachineguns: the Smith & Wesson M76 and the Swedish K (Carl Gustaf m/45). Brownells Gun Tech Keith Ford and Paul Levy from Rock Island Auction Company provide a detailed comparison. The M76 was developed for the U.S. Navy in 1966 as a successor to the Swedish K, which was popular with SEAL teams in Vietnam but faced export restrictions. The M76's design emphasized speed, cost-effectiveness, ruggedness, and ease of repair, delivered by S&W within nine months. The comparison also includes an Egyptian-built Swedish K, offering viewers a direct look at these historical firearms.

This video provides an expert-level overview of the Carl Gustav M/45, commonly known as the Swedish K, presented by Larry Vickers. It details the submachine gun's design, including its unique 36-round magazine, MP40-style safety, and side-folding stock. The review highlights its historical significance, particularly its use by US Special Operations in Vietnam, and mentions licensed variants like the Egyptian Port Said. Vickers' deep knowledge of firearms mechanics and historical context establishes high authority.

This video showcases the Swedish K SMG, specifically the m/45 variant, at Shooters Express in Belmont, NC. It features first-person perspective (FPV) full-auto firing demonstrations and highlights the firearm's historical significance as a vintage collector's item. The review touches on its 9x19mm Parabellum caliber and availability for rent.

The CBJ-MS is a modernized 9mm submachine gun based on the Swedish K, designed as a compact PDW-style platform. It features a unique progressive trigger for semi and full-auto fire without a selector, a grip safety, and a vertical foregrip that stores a spare magazine. The muzzle is compatible with standard M16 bipods for added stability.

This video is a book review of Frank Iannamico's work on the Smith & Wesson Model 76 SMG. The reviewer highlights that the book covers much more than just the Model 76, delving into earlier S&W 9mm carbines (1940 "Light Rifle", 1945 SMG), the Swedish M45/B (Swedish K) and its Egyptian derivative (Port Said), and various experimental variations of the Model 76. It also discusses copies and clones that emerged in the 1980s and 1990s. The reviewer praises the book as a valuable reference for owners and enthusiasts of these firearms, despite wishing for more tabulated data.

The Smith & Wesson Model 76 is a 9mm SMG developed as a domestic alternative to the Swedish K for US forces in Vietnam. While often overshadowed by its Swedish predecessor and later clones, the original S&W 76 is a well-built firearm featuring a simple blowback action, a 36-round magazine, and a folding stock. Its design incorporates features like internal debris clearance grooves and an ambidextrous selector, distinguishing it from the M45.

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.
