This expert-level guide details the disassembly of the Ruger Harrier rifle, emphasizing crucial safety precautions throughout. It covers separating the upper and lower receivers, removing the bolt carrier group and charging handle, and further disassembling the bolt carrier group into its core components. The instructions are clear and actionable, suitable for intermediate users seeking to perform routine maintenance.

This expert guide from Brownells details the critical process of replacing an AR-15 gas key. Instructor Caleb emphasizes meticulous cleaning, precise surface preparation using India stones, and correct installation with Loctite 638 and specific torque values (50-58 inch-pounds) for Grade 8 screws. The final staking procedure ensures long-term reliability by mechanically locking the screws, preventing gas leaks and cycling malfunctions.

This video offers a detailed product spotlight on Brownells AR-15 Bolt-Carrier Groups (BCGs). Paul Levy highlights various configurations and finishes, including Nitride, Parkerized with chrome-lined interiors, Titanium Nitride (TiN), Nickel-Boron, and Hard-Chromed. Special mention is made of the Slick-Side option for Retro Rifle builders and a Lightweight BCG. The description emphasizes the quality of materials (steel alloy), precision machining to military specifications, Magnetic Particle Inspection (MPI) of bolts, proper staking of gas keys, and the use of components from top-tier manufacturers. A Lifetime Guarantee is also a key feature discussed.

This video features Mike Mihalski, founder of Sons of Liberty Gun Works (SOLGW), discussing the critical role of the AR-15 bolt-carrier group (BCG). Mihalski emphasizes SOLGW's "return to fundamentals" approach, focusing on creating a robust, mil-spec BCG with reinforced common failure points rather than innovative but potentially less reliable features. He highlights the importance of materials like Carpenter 158 steel and traditional phosphate finishes, and explains the correct procedures for high-pressure testing and magnetic particle inspection, advocating for proven designs over unproven "new and exotic" materials that could lead to brittleness. The discussion aims to educate viewers on what makes a high-quality and reliable BCG.

This video from Brownells Gun Tech™ explains the critical importance of a properly staked gas key on an AR-15's bolt carrier group. Caleb Savant details how gas pressure cycles the action and why loose gas key screws, caused by insufficient staking, will lead to gas leaks. This prevents proper bolt carrier cycling, rendering the rifle inoperable. The video emphasizes that proper staking is essential for reliable function, whether for recreational shooting, duty use, or personal defense.

This video focuses on a physical swap and gas key replacement for the KAC Sandcutter Carrier. It delves into the technical aspects of modifying or maintaining this specific firearm component, suggesting a focus on gunsmithing or detailed firearm component analysis.

This video provides a practical guide to diagnosing and fixing common AR-15 gas system issues. It details how to identify over-gassing by ejection patterns and suggests solutions like adjustable gas blocks. The content also covers under-gassing causes, such as loose gas blocks or tubes, and emphasizes inspecting the bolt carrier group's gas key and gas rings for wear or leaks. Proper gas tube alignment is highlighted as a critical, often overlooked, factor.

This video delves into the critical topic of gas and carrier keys for firearms, highlighting the discrepancies between "mil-spec" claims and actual product quality. The analysis focuses on distinguishing between good and bad examples, suggesting that not all parts marketed as military-specification meet the intended standards. This content is valuable for firearm owners and builders seeking to understand the importance of component quality and proper specifications.

This video focuses on the maintenance and modification of an AR-15 rifle, specifically detailing the processes of gauging, replacing, and 'dimple' staking the carrier gas key. It aims to provide viewers with the technical knowledge to perform these tasks themselves, contributing to the upkeep and potential customization of their AR-15 firearms. The content is geared towards individuals interested in the mechanical aspects of their rifles and gunsmithing.

This video provides a comprehensive guide to cleaning and maintaining the AR-15/M-16 platform, emphasizing the importance of a clean Bolt Carrier Group (BCG) to prevent stoppages. It details manual and ultrasonic cleaning methods, checks critical components like the gas key for tightness, and explains proper reassembly, including staggering gas ring gaps. The tutorial covers both upper and lower receiver maintenance, bore cleaning, and concludes with a function check.
