Mud Test: 7.5 FK BRNO

Brandon Herrera conducts a 'practical' AK-47 mud test, replicating and exceeding conditions from a previous InRangeTV test. The AK-47, a legally registered machine gun, initially fails to fire after being caked in mud, exhibiting hammer follow due to grit. Minimal cleaning via submersion in stagnant water significantly improves reliability, allowing for semi-auto and full-auto function.

The Gewehr 43 (G43) experienced a critical failure during a mud test, exhibiting a failure to chamber followed by a double feed. The extensive ingress of mud into the receiver prevented the rifle from returning to battery, even after clearing the action. This test highlights the vulnerability of the G43's mechanism to environmental contaminants.

This video details a comprehensive torture test on the Glock 19 Gen 6 at Garand Thumb's range in Idaho. Host Jason subjected the pistol to extreme abuse, including being run over by an ATV and submerged in mud. While mud caused significant issues and broke the plastic rear sight, the firearm remained functional after rinsing, demonstrating notable durability.

This Steyr AUG redux mud test, using the adverse gas setting on a left-handed model, resulted in a failure to eject and a completely jammed charging handle due to mud and debris. Despite attempts to clear the jam with water and 'mortaring' the action, the rifle remained inoperable, highlighting a vulnerability in the charging handle track under extreme conditions.

This InRangeTV video conducts a mud test on the Arsenal SLR104 (AK74) and Valmet M76. Both high-end AK variants initially perform well but ultimately fail when subjected to repeated mud ingress into the locking lug recesses, preventing the bolt from closing. The analysis suggests that while tighter tolerances help initially, the AK design is inherently prone to failure in such conditions once mud reaches critical areas.

The InRangeTV mud test revealed significant reliability issues with the DS Arms FAL. Despite a control group firing flawlessly, the mud-covered rifle failed after only two rounds, specifically failing to return to battery. The non-reciprocating charging handle hindered manual clearing, highlighting a potential vulnerability in harsh conditions. While it outperformed the M1 Garand and M14 in this specific test, the FAL's performance was ultimately deemed a failure.

This video demonstrates the critical failure of a Bulgarian Arsenal SLR104 AK-74 variant when subjected to a mud test. Despite its platform's reputation, the rifle experienced immediate failures to go into battery, eject, and feed due to mud ingress. Repeated attempts to clear the weapon revealed significant friction and a complete mechanical stoppage, highlighting potential reliability issues under extreme conditions.

This video details the anatomy and historical use of 1700s grenades, focusing on their components like the external fuse and internal charge. It demonstrates the ignition process using a slow match and highlights the safety precautions necessary when handling replicas. The content also briefly showcases the hand mortar as an alternative deployment method for these early explosive devices.

This video provides a detailed instructional guide on applying a Gaza-style tourniquet, emphasizing proper technique for effective hemorrhage control. It highlights the importance of initial strap tightening before using the windlass for occlusion and securing it properly. The content also touches upon patient comfort and potential challenges during application.

This video details the historical loading process for the 1836 Colt Paterson revolver. It covers the unique disassembly required, including removing the barrel wedge and the barrel itself. The process involves setting the cylinder to half-cock, charging each chamber with 20 grains of powder and a lead ball, and using a specialized arbor tool to seat the projectile before capping and reassembly.
