LUBE YOUR RIFLES.

This video from School of the American Rifle highlights critical manufacturing defects in AR-15 bolt carrier keys, specifically focusing on rough internal bores. Lead instructor demonstrates how a poorly finished carrier key can cause significant friction, premature wear on components like gas tubes, and operational issues, contrasting a problematic new Colt carrier with a well-functioning older model. The expert emphasizes the importance of a smooth bore for reliable function and longevity of expensive parts.

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 demonstrates John Lovell's preferred method for lubricating an AR-15, prioritizing oiling over extensive cleaning for standard maintenance. Key steps include applying Slip 2000 EWL directly to the Bolt Carrier Group (BCG) through the ejection port and magazine well, ensuring lubrication of vent holes and internal components. The process also covers lubricating the receiver and star chamber, followed by cycling the charging handle to distribute the lubricant effectively.

This guide details the evolution of AR-15 carrier key staking from early 'Gen 1' square staking to modern 'Gen 5' OCKS with serrated heads. It emphasizes proper torque values (vintage 35-40 in-lbs, modern 55-58 in-lbs) and the importance of sufficient metal displacement for screw security. The video, presented by an expert from School of the American Rifle, critiques commercial staking and references historical technical manuals.

This video provides an "autopsy" of an Anderson Manufacturing Bolt Carrier Group (BCG) that failed after only 150 rounds, specifically noting a "sheared lug." The content focuses on a detailed examination of a firearm component failure, suggesting a deep dive into the mechanical aspects and potential causes of the malfunction. This is highly relevant for firearm owners and those interested in the reliability and build quality of AR-15 platforms and their components.

This YouTube video offers practical tips and techniques for polishing stainless steel firearm components. The content focuses on achieving a high-quality finish on gun parts, likely aimed at gunsmiths, hobbyists, and firearm enthusiasts looking to customize or maintain their weapons. The video emphasizes real-world application and likely demonstrates various methods and tools used in the polishing process for stainless steel firearms.

This video humorously illustrates the disruptive effect of a high-concussion muzzle brake, the Rise Armament RA-701, on a public range. The shooter using the brake causes significant side blast and noise, forcing a nearby shooter to stop their own practice. The video satirizes range etiquette and the impact of aggressive muzzle devices.

This satirical review humorously contrasts a 'primitive' Glock owner with an 'enlightened' Sig Sauer owner, highlighting the Sig P365 X Macro. The video showcases the P365 X Macro's features and positions it as a superior choice for those seeking clarity and improved thinking in their firearm ownership.

This video demonstrates that polymer AR-15 lower receivers are significantly less durable than aluminum ones, failing under a single impact. An aluminum PSA lower receiver withstood repeated heavy impacts against a wooden post without functional compromise. The speaker highlights that the small cost difference ($20) makes aluminum a superior choice for durability.

This video humorously illustrates the ATF's shifting stance on pistol braces, depicting an agent initially permitting shouldered use of an AR-15 pistol with an SB Tactical brace, then immediately deeming it illegal and demanding a $200 tax stamp. The content highlights the perceived arbitrary nature of current firearm regulations and the potential for severe penalties, including being labeled a 'violent extremist.' The speaker, demonstrating knowledge of ATF rulings and NFA requirements, conveys a critical perspective on regulatory volatility.
