Agram 2000: Croatia's Gangster Gun

This video analyzes the Springfield Kuna, a new Croatian firearm. It's described as a delayed-blowback PCC/SMG chambered in 9mm, likely featuring a pistol caliber carbine design. The video appears to be from the 'Forgotten Weapons' channel, suggesting a focus on historical context, design, and potential operational characteristics of this less common firearm.

While American-made firearms are valued, many high-quality options are imported from countries like Croatia, Turkey, and Germany. Imported handguns generally maintain high quality, though those from the Philippines and Brazil may be perceived as slightly lower. Caution and thorough research are advised for imported long guns, as high-quality examples are less common than handguns.

The Springfield Armory Kuna is a new roller-delayed blowback PCC, manufactured in Croatia by HS Produkt. It features fully ambidextrous controls, a tri-lug barrel, and an adjustable folding stock. While originally designed for military contracts, a civilian version is expected to launch around $1,000-$1,100 in 9mm, with proprietary 30-round magazines.

The RT20 is a unique Croatian 20mm anti-materiel rifle developed during the Homeland War, utilizing surplus anti-aircraft gun barrels. Its design features a bullpup configuration and a novel gas redirection system to manage the extreme recoil of the 20x110mm Hispano cartridge. While a single-shot bolt-action, its size and recoil necessitate a two-man crew for efficient operation and transport.

This video details the Vugrek 'Nokitel' cell phone gun, a clandestine firearm disguised as a mobile phone. It features four .22 rimfire barrels, each fired by a separate button on the keypad acting as a trigger. The designer, Mirko Vugrek, has a history of illicit firearm manufacturing, including this device and the Agram 2000.

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 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.
