Stop rifle over-gassing with your bolt carrier group and buffer system

This video provides a detailed, step-by-step explanation of the AR-15 Bolt Carrier Group's (BCG) eight primary functions during the firing cycle. It breaks down the complex physics of gas operation, bolt unlocking and locking, extraction, and ejection, clarifying common misconceptions about how the BCG operates. The explanation is delivered with a focus on technical accuracy, making it valuable for intermediate AR-15 users.

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 guide details a basic cleaning procedure for an AR-15, recommended every 500 rounds. It covers field stripping the upper receiver, cleaning the barrel with a bore snake, cleaning the bolt carrier group (BCG), and proper lubrication of key contact points. The process emphasizes not over-lubricating to prevent carbon buildup. The video is presented by Justin from Palmetto State Armory.

This guide explains the benefits of using .22LR conversion kits or dedicated uppers for AR-15 platforms, primarily for cost-effective training and introducing new shooters. It highlights how these systems allow practice of essential firearm manipulations at a fraction of the cost of centerfire ammunition. The guide also touches on important considerations for bolt carrier groups, such as MPI inspection, material quality, and coatings, differentiating between options for high-volume training and critical applications.

This video provides a detailed comparison between the AR-15 and AR-308 platforms, highlighting key differences in components and compatibility. It explains that while some lower receiver parts like springs, selectors, and trigger mechanisms (with heavy hammers/springs) can interchange, major components like the bolt carrier group, charging handle, and upper receiver are platform-specific due to size and cartridge differences. The discussion also covers barrel nut variations, muzzle device thread pitches (1/2x28 for AR-15, 5/8x24 for AR-308), gas block diameters, and the importance of matching receiver height (high vs. low profile) with handguards for proper alignment. It emphasizes that AR-308 components are less standardized than AR-15 parts, with DPMS pattern being the most common but variations like ArmaLite and DPMS Gen 2 requiring specific attention.

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 operation of the FightLite MCR belt-fed upper receiver, as demonstrated by a professional tactical content creator. It covers preparation, proper belt feeding, and executing controlled full-auto fire strings through a barricade. The video highlights the weapon's performance and the shooter's satisfaction.

This video demonstrates the sound reduction capabilities of a suppressed Glock 19 pistol. It showcases a customized firearm equipped with a Trijicon SRO red dot sight and a SureFire X300 weapon light. The demonstration highlights the significantly reduced report of 9mm rounds when fired outdoors with a suppressor, emphasizing the effectiveness of the accessory.

This guide outlines a progressive approach to firearms training, emphasizing mastering skills 'slick' before integrating restrictive gear like plate carriers and helmets. The Barrel & Hatchet Instructor highlights the importance of gradually adding equipment to ensure proficiency is maintained and to test gear functionality under realistic conditions. This method ensures foundational skills are solid before introducing the complexities of operating with a full kit.

This guide details the customization of a Smith & Wesson M&P Metal 2.0 pistol, focusing on the installation of an optic, weapon light, threaded barrel, and compensator. The speaker, a tactical instructor, shares his personal build choices, highlighting the versatility and performance enhancements achieved through these aftermarket upgrades. The process involves mounting a Trijicon SRO, a Surefire X300 Vampire light, and a Griffin Armament barrel and compensator combination.
