This guide from AT3 Tactical provides a simple yet effective hack for correctly aligning an AR-15 gas block. By using the barrel's existing markings as a visual guide, users can ensure proper gas port orientation, preventing cycling issues. The presenter, with high authority in AR-15 assembly, demonstrates how to align the gas tube and block to cover these markings when viewed from above.

This video details modifications to an Albanian AK, enabling grenade launching capabilities. Key changes include a rebuilt rear sight block, a flat-topped receiver cover with a locking pin, and a grenade launcher spigot at the front. The spigot appears to function as a retention mechanism for the grenade, and an integrated gas cut-off lever is noted.

This video provides a comprehensive first look at the Meridian Defense MDC-101 and MDC-103, focusing heavily on the MDC-101 as a highly accurate AK-101 clone. The review highlights the firearms' clone-correct features, cold hammer-forged and chrome-lined components, and impressive reliability and shootability, particularly the soft recoil impulse of the 5.56 variant. The speakers, including gun quality enforcement expert Jacob Fox, emphasize the value proposition compared to imported or modified AKs, suggesting these American-made rifles set a new standard.

This entry details the experimental M1E10 Garand-Ljungman Prototype, focusing on its unique gas system inspired by the Swedish Ljungman rifle. Expert analysis by Ian McCollum highlights the design's attempt to simplify the M1 Garand's operating rod by using a direct impingement gas system. However, significant overheating issues caused by gas venting into the wooden stock ultimately led to its failure as a viable military firearm, despite potential manufacturing benefits.

This guide details essential quality control checks for budget or 'blem' AR-15 builds, emphasizing the need for user verification of critical components. Lucas Botkin, an established industry professional, demonstrates the use of specialized tools to ensure proper torque on the barrel nut, gas block, and castle nut, crucial for safety and reliability.

This video clarifies the function of the AK 'gas tube,' explaining that it is not critical for the rifle's operation, unlike the AR-15's gas tube. The AK's cycling mechanism relies on gas entering the gas block to push a piston. The 'gas tube' primarily aids in piston guidance and protects the gas block from debris. The speaker, from AK Operators Union, Local 47-74, emphasizes that an AK will still function without a gas tube, though its protective role is diminished.

This video provides a detailed comparison between Direct Impingement (DI) and Gas Piston AR-15 operating systems. It clarifies the fundamental mechanical differences, explains how each system cycles a firearm, and discusses the practical implications for heat, cleanliness, reliability, and cost. The presenter highlights the advantages of piston systems, particularly when using suppressors, while acknowledging that properly tuned DI systems can also perform exceptionally well.

This video discusses gas block options for an AR-15 build, specifically for a 300 Blackout caliber. It presents three choices: a basic milspec gas block, a WOE adjustable gas block, and a Strike Industries adjustable gas block, allowing the audience to vote on the final selection for the Audiencebuilt AR project.

This video breaks down the different AR-15 gas tube lengths (Pistol, Carbine, Mid, Rifle, and Intermediate) and their impact on shooting dynamics. The presenters demonstrate how barrel length and gas system choice affect recoil, muzzle rise, and overall shooting experience, emphasizing that the 'best' system depends on the intended application and build.

This guide details the disassembly and internal component overview of the Chinese Type 79 SMG, drawing from expert analysis. It highlights the AK-style fire control group and the unique integrated trunnion/gas block/feed ramp component. The information is presented with a high degree of technical detail, suitable for advanced users.

This video provides an expert-level overview of an Armalite AR-18 parts kit, detailing its components and historical context. Mark Serbu, a gun designer, examines the kit, highlighting its origins from Sterling in England, Costa Mesa, California, and Hawa Hoa in Japan. He discusses the differences between the AR-18 (machine gun) and AR-180 (semi-auto), noting the auto sear's location in the upper receiver. The video also touches on the unique gas system with a fixed piston and moving cylinder, the barrel extension integrated into the trunnion, and the challenges of repairing a torch-cut receiver.

This video details the historical evolution of the AR-15 handguard, from early polymer designs to modern modular systems like Keymod and MLOK. It highlights key innovations driven by military and competitive shooting needs, emphasizing the shift towards free-float designs and the impact of accessory mounting interfaces on weapon performance and modularity.
