MG38: Colt's Interwar Water-Cooled Machine Gun

The Colt MG38, based on the Browning Model 1917, featured significant design improvements like self-contained recoil springs and a higher rate of fire (up to 850 RPM) achieved by lightening the bolt. The 'B' designation in MG38B specifically indicated models sold with spade grips, differentiating them from earlier or standard configurations.

The M1922 BAR was a rare light machine gun variant developed from the M1918 BAR, featuring a heavier barrel and bipod for sustained automatic fire. While Colt produced commercial versions, only 500 M1922s were converted from existing stocks before being declared obsolete in 1941. Key features include cooling fins on the barrel and a rear monopod for stability, though it was less ergonomic for left-handed shooters.

The Marlin Model 1917, a licensed Colt Model 1895 'Potato Digger' variant, was a significant early gas-operated machine gun. Initially adopted by the US Navy, it later served as a crucial training weapon for the US Army during WWI due to Colt's production constraints. A redesigned aircraft variant with a linear gas piston was also produced, highlighting its adaptability.

TheYankeeMarshal, an experienced firearm enthusiast, discusses his perceived shortcomings as a firearm salesman. While knowledgeable about firearms, he admits to struggling with creating a sense of urgency or convincing potential buyers of their 'need' for a product, which he identifies as a critical sales skill. His background, featuring a collection of revolvers and pistols, underscores his deep familiarity with firearms.

The Stinger was a custom USMC weapon built from an AN/M2 aircraft machine gun, featuring a BAR bipod and M1 Garand stock. Modified for ground use, it had a high rate of fire (1400 rpm) and reduced ammo capacity (100 rounds) for portability. This unique firearm was famously used by Tony Stein during the Battle of Iwo Jima.

This video explores the real-life firearm that inspired Marty Robbins' 'Big Iron' song and compares it to a modern powerhouse, the Magnum Research BFR in .500 S&W Magnum. The custom 'Big Iron' recreation features a 10-inch Winchester barrel on a Great Western frame, chambered in .44-40. The BFR, a massive single-action revolver, demonstrates extreme recoil and terminal ballistics with the .500 S&W Magnum cartridge, far surpassing the .44-40 in destructive power during penetration and ballistic gel tests.

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.
