KH-9: B&T Remakes the SITES Spectre Just Because It's Cool

This video announces the upcoming release of the limited production Swiss-made BT96, described as a Swiss MP5. The description highlights the rarity and impending availability of this firearm.

Alyssa Seymour provides an in-depth look at the B&T KH9S, a modern submachine gun drawing inspiration from iconic WWII and Cold War designs like the Sten and Sterling. The review highlights its unique side-feeding magazine, top-mounted charging handle, and tri-lug barrel for suppressor compatibility, emphasizing its heritage and modern features.

The B&T KH9-SD revives the 1980s Site Spectre design as a modern, integrally suppressed submachine gun. It features a ported barrel system to subsonic standard 9mm rounds, offering exceptional quietness. Despite its direct blowback action, it exhibits manageable recoil and high controllability, enhanced by Swiss engineering. The KH9-SD also boasts modular magazine compatibility, including Suomi drums, and a unique DA/SA trigger, positioning it as a high-end, retro-inspired collector's item.

The B&T APC9K SD is an integrally suppressed submachine gun, adopted by the US Army, featuring a two-stage suppressor system for enhanced quietness. Its ported barrel slows supersonic 9mm rounds to subsonic speeds, and it offers lower receiver options for B&T or Glock magazines. The hydraulic buffer system ensures a flat shooting experience with minimal recoil.

This review covers the B&T MP9, highlighting its iconic status and a new 3D-printed titanium suppressor. The new suppressor offers improved performance, reduced weight, and HUB compatibility for broader use on 9mm firearms, retailing at $850. The MP9 itself is shown in a full-auto demonstration, emphasizing its compact and select-fire capabilities.

This review details the Heckler & Koch MP5K PDW, focusing on its compact design, 9mm caliber, and 30-round capacity. Key features include a B&T collapsible stock, unique castle-style drum sights, and compatibility with an RS9 suppressor via direct thread. The firearm is presented as a high-performance SMG suitable for personal defense.

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.
