Water-Cooled .50s: The US Navy Mk22 Pedestal Mount

The Colt MG52-A is a water-cooled .50 caliber heavy machine gun developed from John Browning's designs. Originally the Model 1924, it was later designated MG52 (water-cooled) and MG53 (aircraft). It featured a dual-feed capability and a complex ladder sight, but had a difficult charging handle compared to the later M2 Browning. Approximately 11,000 units were sold internationally before WWII, with the MG52-A becoming rare in the US.

The Manda is a minimalist .50 BMG single-shot sniper rifle developed by Croatia's Ministry of the Interior during the Homeland War. Utilizing repurposed Browning M2 barrels and featuring a unique BDC scope mount, it was designed for simplicity and effectiveness. Only 84 were produced between 1991 and 1994, serving with the Croatian Special Police before being retired.

The Cobray Terminator is critically reviewed as one of the worst shotguns ever made, featuring a crude design allegedly using M2 Browning .50 BMG barrel shrouds. Its slam-fire mechanism and unique, difficult loading procedure contribute to extreme recoil and poor handling, making it a low-quality firearm.

This video announces the release of 'Small Arms of WWII - United States' by Ian McCollum and Headstamp Publishing. The comprehensive 500-page book covers a wide array of American small arms from the era, including pistols, rifles, submachine guns, and heavy machine guns, with detailed photography and historical context. It is available for pre-order directly from the publisher.

Platinum rapper Money Man joins Demolition Ranch's Matt Carriker to test some of the most expensive firearms available. The lineup includes a Taran Tactical Sand Viper, a full-auto AK-47, a CheyTac M200 Intervention, a Barrett M107, and a Browning M2 'Ma Deuce'. Money Man shares his preferences, highlighting the Sand Viper's trigger, the AK's performance, and the M2's raw power, while promoting his album 'Purple Heart'.

This analysis debunks case head separation as the cause of the RN-50 explosion, highlighting its fixed 0.200" headspace and internal brass plug support. Unlike the M2 machine gun, which relies on headspace for safety, the RN-50's design prevents pressure from venting into the action even with hypothetical case failures. Future parts will address SLAP rounds and cap vent theories.

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.
