Shooting the Worlds Shortest AR15

This guide details how to adjust the gas system on the HK MR556 A4, a civilian variant of the HK 416. The rifle features an adjustable piston-driven gas system with two primary settings (Normal/Suppressed) and an advanced 15-position fine-tuning capability. Proper adjustment is crucial for optimal performance, especially when using a suppressor, minimizing gas blowback and ensuring reliability.

This guide outlines seven essential firearms for a zombie apocalypse scenario, emphasizing practicality, logistics, and reliability over aesthetics. The selections include a 16-inch AR-15 carbine in 5.56 NATO, a Glock 19 Gen 5 in 9mm, a 12-gauge pump shotgun, a .357 Magnum lever-action rifle, a .357 Magnum revolver, a 9mm PCC, and a suppressed .308 bolt-action rifle. Each choice is justified by its specific advantages in maneuverability, ammunition availability, shootability, and effectiveness in various survival situations.

This video reviews the HuxWrx Flow 556 TI suppressor after 1,000 rounds. The instructor emphasizes its lightweight design and effective muzzle flash reduction, suggesting suppressors are increasingly important for tactical advantage in 2026. While sound suppression is good, flash reduction is highlighted as the primary benefit.

This review of the Ridgeback Rhodie 6 suppressor highlights its hybrid diameter design, forward venting system, and Inconel construction. Instructor Aaron C. of Sage Dynamics found it to be exceptionally reliable across various platforms, including short-barreled rifles and full-auto configurations. The suppressor demonstrated excellent performance in managing gas, reducing recoil pulse, and maintaining a low muzzle signature, even under night vision conditions.

This video tests the ballistic resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. It demonstrates that even smaller rounds cause superficial damage, while larger calibers like 7.62x39mm and 5.56mm create significant dents and fragmentation. The .50 BMG round causes the most substantial damage, but the hammer remains intact, suggesting a high degree of ballistic resistance.

This video outlines ten essential firearms for potential conflict scenarios, emphasizing practicality, reliability, and logistical considerations. It covers the AR-15 in 5.56 NATO for its widespread parts and familiarity, the AKM in 7.62x39mm for its durability and tolerance for harsh conditions, and the Glock 19 class in 9mm for its balance of size and capability. The discussion extends to full-size duty pistols, 12-gauge pump-action shotguns for close-quarters effectiveness, .22 LR rifles for logistical efficiency and small game, and .308 Winchester rifles for extended range and barrier penetration. The importance of suppressor-ready platforms for reduced blast and improved shooter endurance is also highlighted.

This video from DemolitionRanch, hosted by Matt Carriker, explores the capabilities of high-powered, regulated air rifles like the AirForce Texan SS and Sam Yang Dragon Claw. Carriker demonstrates their impressive power, accuracy, and surprisingly quiet operation due to integrated suppressors, highlighting a legal loophole where these airguns and their suppressors are not subject to NFA regulations. The content showcases ballistics testing and comparisons, emphasizing the expert knowledge of the host in firearms and related legalities.

This video features Nicholas Irving, a former Special Operations sniper, demonstrating and discussing various high-powered firearms. Irving, author of 'Way of the Reaper,' shares insights on sniper rifles like the Barrett M107A1 and SR-25, discusses the recoil of the S&W 500 Magnum, and tests the penetration capabilities of different calibers against an engine block. The content highlights practical applications and the effectiveness of these weapons in tactical scenarios.

This video demonstrates the dangerous consequences of firing incorrect ammunition calibers in firearms. Experienced instructor Matt Carriker shows how .380 ACP in a 9mm firearm and 9mm in a .40 S&W firearm can lead to cycling failures and severe brass deformation due to improper headspacing. The experiment highlights the critical importance of using the correct ammunition for each firearm to ensure safe operation and prevent damage.

This video from DemolitionRanch, featuring firearms expert Matt Carriker, tests the ballistic resistance of Flex Tape when used as improvised body armor. The experiment involves layering Flex Tape onto cardboard and testing its effectiveness against .22 LR, 5.7x28mm (FN PS90), and 9mm (CZ Scorpion Evo 3 S1) rounds. The results demonstrate that even extensive layering of Flex Tape is insufficient to stop common firearm calibers, highlighting the importance of proper ballistic materials.
