Calico Light Weapons System: Roller Delay and Helical Drums

The Grand Power Stribog SP9A3s, or 'Mini Bog,' is a highly compact 9mm pistol utilizing a roller-delayed blowback system for reduced recoil. This review highlights its ambidextrous controls, improved magazine reliability with new curved options, and various brace configurations. The SP9A3s offers competitive value, especially considering its advanced action and compact design.

The Gerät 06 represents a crucial evolutionary step in German firearm design, bridging the gap between the G43 and the later Heckler & Koch roller-delayed blowback systems. Initially a gas-operated, roller-locked rifle, its development led to the discovery of the roller-delayed blowback principle by exploiting 'bolt bounce.' This innovation paved the way for lighter, cheaper, and more efficient firearm designs.

This video features a review of the Grand Power Stribog pistol, highlighting its versatility as a Pistol Caliber Carbine (PCC) platform. The reviewer demonstrates various Stribog models, discussing their differences and potential for customization with accessories like suppressors and optics. The A3 models are specifically mentioned for their roller-delayed blowback system, which reduces felt recoil. The review encourages viewers to consider the Stribog for their wishlist, emphasizing its adaptability for different calibers and configurations.

This video explains the inner workings of the Heckler & Koch P9S, a discontinued roller-delayed blowback handgun. It highlights the P9S's unique operating system and mentions its chamberings in 9mm and .45 ACP. The description emphasizes its historical significance as a notable firearm from the past, even though it's no longer in production. This content is ideal for firearm enthusiasts interested in the mechanics and history of specific handgun designs.

This review covers the PTR GI, an American-made G3 clone chambered in 7.62x51mm NATO. It highlights the rifle's historical significance, technical specifications like its roller-delayed blowback system, and practical range performance. The PTR GI is presented as a robust battle rifle, capable of reliable operation and decent accuracy at 200 yards despite a heavy trigger.

This video provides a humorous and opinionated comparison between the Matador Arms Mat9 and the Mac N Cheese V2.5. It highlights key mechanical differences, such as the Mat9's roller-delayed blowback system and monolithic upper versus the Mac N Cheese's straight blowback and MAC-11 upper. The video also touches on the philosophical implications of home-made firearms in relation to government control.

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.
