This video from AT3 Tactical explores the function and necessity of the forward assist on AR-15 style firearms. It delves into the component's historical origins, specifically its introduction during the Vietnam War era, and examines its practical applications and potential drawbacks on modern rifles. The content aims to educate viewers, whether they are new to building or modifying AR-15s, to make an informed decision about the forward assist's role in their firearm setup. The video also touches on specific drills and potential problems associated with the component.

This guide, presented by School of the American Rifle, details how to identify and replace a malformed weld spring in an AR-15 Delta Ring assembly. A misaligned weld spring can cause the gas tube to be pushed off-center, leading to excessive friction or damage to the carrier key and gas tube. Replacing the faulty component ensures proper gas tube alignment and firearm reliability.

This video provides a comprehensive, step-by-step guide to building a .300 Blackout AR-15 pistol. Caleb from Brownells walks viewers through the entire process, from selecting top-tier components from manufacturers like Aero Precision and Sons of Liberty Gun Works, to detailed assembly of the lower receiver, upper receiver, gas system, and the installation of accessories such as optics and lights. The guide offers valuable tips on essential techniques like staking castle nuts and setting torque specs, making it an ideal resource for both novice builders and those seeking to learn more about AR-15 customization.

This YouTube video focuses on a common and crucial aspect of firearm ownership: the buffer system. The title, "What buffer system do you use?", directly asks for viewer input on their preferred buffer systems. While the description is empty, the title alone indicates a discussion or inquiry into different buffer systems, which are vital components for the reliable operation of firearms, particularly semi-automatic rifles like the AR-15 platform. Viewers interested in firearm maintenance, customization, or performance optimization would find this content relevant.

This video focuses on AR-15 lower parts kits, guiding viewers on how to select the right one for their build. It highlights the importance of understanding the differences between kits to ensure a successful firearm assembly. The description also encourages viewers to sign up for CMMG Insider updates and provides links to CMMG's website and social media channels for more information on releases and company news.

This video explores the theoretical and practical outcome of loading a 50 BMG cartridge into a 12 gauge flare gun. The experiment, conducted by a hobbyist, demonstrates that while the 50 BMG cartridge surprisingly fits, the flare gun's firing mechanism and primer strength are insufficient to ignite it. The test highlights the significant differences in primer resistance between ammunition types.

This video debunks the myth that shooting upwards is safe, explaining the lethal terminal velocity of falling projectiles. It showcases the Canik Mete MC9 Prime with a Gideon Valor optic and demonstrates the use of 9mm shot shells for controlled, less dangerous demonstrations, highlighting their unique projectile dispersal.

This video debunks the myth that a .50 BMG round passing near a target can be lethal due to shockwave. Using a ballistic mannequin head and a Big Kahuna Firearms Raptor-50 rifle, the test demonstrated that while the .50 BMG round impacted and destroyed a concrete block behind the target, it did not affect the mannequin or the cardboard placed near it. The conclusion is that a near miss from a .50 BMG is not fatal.

This video conducts a destructive test comparing the impact of .22 LR and .50 BMG rounds on a ballistic head model. The .22 LR caused minimal damage, while the .50 BMG completely destroyed the head, highlighting the vast difference in energy and destructive potential between the two calibers. The test also showcases the Raptor .50 BMG upper receiver as an accessible way to experience .50 BMG ballistics on an AR-15 platform.
