This expert-level guide details the proper cleaning procedure for the Ruger Harrier rifle, as demonstrated by an instructor from the official Ruger Firearms channel. It covers essential tools, step-by-step instructions for cleaning the bore, bolt, bolt carrier, and firing pin, emphasizing critical inspection points for reliable function. Safety precautions are highlighted throughout the process.

This guide details 17 habits for extending the life of an AR-15, drawing on military armorer data. Key practices include listening to the rifle for early warnings, adhering to specific cleaning intervals, inspecting critical components like bolts and springs, using appropriate lubricants, and managing heat. Following these steps can help an AR-15 exceed 20,000 rounds of reliable service.

This video provides an abbreviated autopsy of a KAK K-Spec bolt carrier group, identifying significant gassing issues. The inspection reveals leaks at the carrier key and bolt tail, an oversized bolt tail opening in the carrier, and an improperly machined internal transition that can damage gas rings. The dual ejectors and weak extractor spring are also noted as potential contributing factors to poor performance.

This comprehensive guide from CJ at AT3 Tactical details the complete disassembly and reassembly of an AR-15 Bolt Carrier Group (BCG). It covers field stripping using minimal tools and then proceeds to a full deconstruction, including the extractor, ejector, and gas rings, with recommended tools and techniques for each step. The guide emphasizes proper lubrication and function checks for reliable operation.

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 provides an in-depth look at common wear points on a Rock River Arms Bolt Carrier Group (BCG). It highlights issues with gas rings, specifically a wide gap indicating potential failure, and a damaged cam pin due to excessive friction. The instructor recommends replacing these parts to ensure continued serviceability of the BCG.

This video discusses wear patterns on firearm components, specifically focusing on the bolt carrier group and bolt. It highlights the importance of even wear across these parts and addresses concerns like carrier tilt in AR-15 style actions, noting that some designs, like the HK416, mitigate these issues.

This video provides a practical guide to maintaining the gas rings on an AR-15 bolt carrier group. It demonstrates how to test the functionality of gas rings by standing the BCG on its end and offers a step-by-step method for removing and installing these critical components using simple tools like a dental pick. The instructor emphasizes that proper gas ring function is vital for reliable AR-15 operation.

This guide details a common technique for inspecting the gas rings on an AR-15 Bolt Carrier Group (BCG). The video demonstrates that an H&R M16A2 build from Palmetto State Armory failed the "stand test" for its BCG after only 2,000 rounds, indicating worn gas rings. This test is a quick way for experienced shooters to assess BCG health.

This video details troubleshooting a Noveske N4 Switchblock that experienced significant malfunctions, including light strikes, extraction failures, and ejector issues, after approximately 800 rounds. The presenter found the Switchblock to be finicky with buffer systems and explored swapping components, including a Centurion bolt carrier. After returning to factory parts and cleaning, the rifle appeared to function correctly, though the exact cause of the initial problems remains somewhat unclear, potentially related to gas rings or component tolerances.

This video, featuring firearms instructors Jason and Matt from Classic Firearms, details the five most common wear items on a traditional Direct Impingement (DI) AR-15. They emphasize practical experience over internet research, covering the extractor, gas rings, firing pin, buffer spring/castle nut area, and handguard retaining screws. The discussion includes how ammunition type (brass vs. steel) affects wear and offers practical tips like using witness marks for screw security.

This comprehensive analysis from Garand Thumb details a rigorous torture test on a $400 Palmetto State Armory Freedom Rifle AR-15. The test simulates extreme wear through thousands of rounds of suppressed, full-auto fire, documenting accuracy degradation, component wear (gas rings, extractor spring), and comparing performance against a Knight's Armament SR-15. The findings provide valuable insights into the durability and limitations of budget-friendly AR-15 platforms under harsh conditions.
