This video provides an in-depth look at Beretta's new NAR (New Assault Rifle) platform, intended as the next service rifle for the Italian Army. The review highlights its development process, extensive testing under NATO AC225 standards, and key technical features. It emphasizes the platform's reliability, modularity, and ergonomic design, drawing comparisons to the AR-15 while showcasing unique Beretta innovations.

This guide outlines a 10-minute monthly maintenance routine for AR-15 owners to ensure longevity and prevent malfunctions. It emphasizes proper lubrication of the bolt carrier group (BCG) and strategic cleaning, rather than excessive scrubbing. Key steps include the gas ring test and careful barrel cleaning to avoid damaging the crown.

This video delves into the intricate mechanical design of the M1 Garand rifle, with animator Bruno detailing the complexities he encountered while animating its components. Key areas of focus include the convoluted bolt design, the non-linear cycling action, the challenging recoil spring system, and the precise machining required for parts like the clip release and the accelerator. The discussion highlights the unique engineering choices made during the Garand's development and contrasts them with more modern design philosophies.

This video compares the 6MM ARC and 6MM MAX cartridges, highlighting their technical differences, performance, and practical applications. While the 6MM ARC has gained significant traction and military adoption, the 6MM MAX offers potential advantages in AR-15 compatibility due to its use of a standard 5.56 bolt. However, the performance differences are noted as minuscule in real-world scenarios, with availability and existing adoption favoring the 6MM ARC.

This video provides an in-depth look at a Guatemalan contract Armalite AR-10, manufactured by AI Artillery. It details the rifle's history, its unique features like the ventilated bayonet shroud and fiberglass furniture, and its internal mechanics, highlighting its similarity to the AR-15. The presenter, Ian McCollum, demonstrates the field stripping process, emphasizing the gas piston system within the bolt carrier.

This video provides a direct comparison between Faxon and Centurion 6.5 Grendel bolts, highlighting their construction and features. The Faxon bolt is described as very milspec, nitrided 9310, well-built, and affordable, featuring milspec gas rings and a clean finish. The Centurion bolt is noted for its beefier lugs, hard chrome finish, and dual ejectors, with an upgraded spring in the extractor. Both bolts are Type 2 and come with a lifetime warranty.

This video details the first shots of a custom 6mm ARC AR-15 build. The presenter highlights specific components like a Rainier Arms barrel, BCM thermal fit, Griffin Armament lower, and Adabal 110 optic. Initial testing reveals cycling issues, particularly with ASC magazines, leading to troubleshooting and a comparison of Faxon and Centurion bolt carrier groups. Velocity data and accuracy observations are provided, with a focus on identifying and resolving build-specific problems.

During ammo shortages, the next items to disappear are magazines, reloading components, and gun parts. The video highlights that during the 2020 shortage, specific magazines like Glock and AR-15 Pmags became scarce and expensive. Reloading primers vanished almost overnight, while powders remained available but restricted. Gun parts for popular platforms like AR-15s (lower parts kits, BCGs) and Glocks also saw significant demand and scarcity, impacting repairs and builds.

This video demonstrates the correct procedure for checking a firearm's barrel for obstructions. It emphasizes that looking down the barrel from the muzzle end and seeing no 'daylight' is not a reliable indicator of an obstruction, as the bolt face will naturally block the view. The correct method involves disassembling the firearm, removing the bolt carrier group, and then inspecting the barrel from the breech end.

This guide details the essential steps for lubricating a new AR-style rifle before its initial firing, as demonstrated by an experienced instructor. It covers proper disassembly, specific lubrication points on the bolt carrier group and trigger mechanism, and reassembly. The video emphasizes the importance of lubrication for new firearms, drawing a parallel to car maintenance, and highlights the performance of the We The Pieu MX1 lubricant in hot conditions like those found in Utah.

This video from CF Clips discusses a potential issue with the SIG Sauer MPX firearm and its compatibility with FRT (Forced Reset Trigger) triggers. The core problem identified is the MPX's heavy bolt, which can reportedly damage or break FRT triggers due to the force of the bolt carrier group impacting the hammer. This insight comes from direct communication with FRT manufacturers, who have confirmed the MPX's harshness on their triggers.

This review covers the CMMG 22LR AR conversion kit, demonstrating its simple installation by replacing the standard BCG. The video highlights the importance of ammunition quality for reliable cycling, with CCI Mini-Mags performing best. It also touches on the kit's compatibility with Mil-spec AR-15 uppers and its last-round hold-open feature.
