MSBS Grot: The Complete History of Poland's New Army Rifle

The MSBS Grot ceremonial rifle, adopted by the Polish military in 2016, features a straight-pull bolt action and a 20-inch barrel for parade use. Modifications include a locked bayonet lug, a smooth rail cover, an enlarged right-side charging handle, and a disabled right-side magazine release. The fixed stock is reinforced for durability during drills, and it uses a 10-round blank magazine.

This video reviews the MSBS Grot rifle in its standard, bullpup, and 7.62x51mm configurations. The standard 5.56mm version is noted for its pleasant shooting experience and modularity, including left-hand ejection. The bullpup variant is significantly more rear-heavy, leading to increased muzzle jump. The 7.62x51mm model features a heavy barrel and remains comfortable to shoot despite the larger caliber.

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.
