MAC/Skorpion Hybrid at the Range: the Alka M93

The Crogar M91 is a rare Croatian submachine gun developed during the 1991 Homeland War, featuring an open-bolt design and utilizing Yugoslavian M56 magazines. Its construction shows MP40 influence, particularly in the telescoping recoil spring. Production was limited, with most examples phased out after the war.

The Alar SMG was an emergency submachine gun produced by students in Sisak, Croatia, during the early Croatian Homeland War. Early prototypes featured simple mechanics inspired by the PPSh-41, while later production versions incorporated side-folding or under-folding stocks and rifled barrels smuggled from Austria. Approximately 80 units were made before production ceased as more standard arms became available.

The HS-91 is a unique Croatian submachine gun from the 1991 Homeland War, blending features of the Yugoslav M56 and Russian PPSh-41. This video details its hybrid design, markings, and a distinct side-latch disassembly method, differing from the PPSh-41. Expert analysis highlights its historical context and manufacturing origins.

The Kresimir is a unique semi-automatic grenade launcher developed in Croatia during the Homeland War. It fires M50 hand grenades using 7.62x39mm blank cartridges for propulsion, a complex two-stage firing sequence that first ignites the grenade's timer and then fires the blank. The weapon features a mechanical charging handle due to its heavy bolt and a reciprocating magazine, with sights graduated up to 500 meters.

This review of the Springfield Armory Kuna highlights its unique roller-delayed operating system, designed for reduced recoil and a smoother shooting experience. The pistol is chambered in 9mm, features a 30-round capacity, and boasts fully ambidextrous controls. Expert analysis points to its potential as a Personal Defense Weapon (PDW) with superior stability and faster follow-up shots compared to traditional handguns.

The ALKA mod 93 is a Croatian submachine gun developed during the Homeland War, influenced by the MAC-11 and Vz. 61 Skorpion. It features a robust sheet metal construction, a high rate of fire (~1200 rpm), and a compact design. Despite its origins, it's noted to handle better than a standard MAC-10.

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.
