Suppressed OSS M3 Grease Gun and Bushmaster Booby Trap Trigger

This video compares a suppressed Thompson M1A1 prototype with the Sten Mk.IIS, detailing the Thompson's unique suppressor design and modifications. Despite comparable muzzle noise, the Thompson's significantly louder mechanical action and heavier, longer profile led to its abandonment in favor of the M3 Grease Gun in 1944 trials.

Hank Strange provides an expert review of the M3 Grease Gun, highlighting its unique manual of arms, including the internal crank-style charging handle. He demonstrates its operation and live fire, noting its 'humming like a sewing machine' cyclic rate and historical context as a 1943 suppressive fire weapon. The review emphasizes the importance of understanding its specific loading procedure.

This expert review of the M3 Grease Gun covers its .45 ACP direct blowback operation and open-bolt configuration. The demonstration highlights the original ratcheting charging handle, the weapon's slow and controllable rate of fire, and its performance on an outdoor range. The reviewer, identified as an expert, showcases practical handling and firing techniques.

The Welrod MkII is a unique bolt-action pistol designed for clandestine operations during WW2, chambered in .32 ACP. Its integrated suppressor is exceptionally quiet initially, producing a 'loud thump' rather than a crack. However, the suppressor's internal wipes degrade after about 10 rounds, diminishing its effectiveness and increasing the sound signature.

This review of the CMMG Dissent MKG 45 highlights its .45 ACP chambering and effective integration of accessories, including a Unity Riser, EOTech optic, Reptilia grip, and Tac Pack foregrip. The video features the new CMMG 46K suppressor and demonstrates its performance during live fire, noting the manageable recoil despite the potent .45 ACP round. The presentation is from an experienced firearm instructor.

This review compares the MP5K with and without a suppressor, demonstrating the significant reduction in sound and muzzle flash. The HK SP5K-PDW, chambered in 9mmx19, is shown to be a compact and effective platform for suppressed fire. The video highlights safe handling and controlled rapid fire, showcasing the firearm's performance on an outdoor range.

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.
