This video debunks the widespread claim that Colt revolvers are failing due to MIM (Metal Injection Molding) hammers. The speaker, TheYankeeMarshal, argues that while Colt does use MIM parts, including hammers, this is common across many manufacturers like Smith & Wesson, Taurus, and Ruger. He attributes isolated failures to manufacturing defects, not an epidemic, and explains that modern MIM processes produce parts as durable as older forged components. The video emphasizes distinguishing between individual failures and systemic issues, urging viewers to be critical of internet hysteria.

This video provides an in-depth analysis of the FBI's technical evaluation of a Sig Sauer M18 pistol that allegedly discharged uncommanded from its holster. It details potential design flaws, manufacturing defects, and user-related factors contributing to unintended discharges, drawing on a Michigan State Police incident and FBI testing.

This video features LFD Research detailing their investigation into uncommanded discharges of the SIG P320. They demonstrate how specific part combinations, tolerance stacking, and manufacturing variations can lead to the firearm firing without a trigger pull. The discussion highlights potential design flaws and the importance of understanding firearm mechanics for safety and reliability.

This YouTube Short discusses potential quality control issues with Smith & Wesson firearms. The title and brief description suggest a critical look at the manufacturing or reliability of S&W products. This video is likely aimed at firearm owners and enthusiasts interested in brand reputation and potential problems.

This video identifies the five most common reasons semi-automatic pistols jam: underpowered ammunition, poor lubrication, a dirty firearm, limp wristing, and manufacturing defects. The instructor emphasizes regular cleaning and proper lubrication as crucial preventative measures. He also notes that persistent issues, even with proper maintenance and good ammunition, may indicate a defect requiring professional attention.

This entry details Colt's historical issue with hard chrome plating on M16 bolt carrier groups. Despite hard chrome being a sound concept for the BCG, Colt's attempt to perform the plating in-house to save costs led to substandard results. The plating failed to meet specifications, causing flaking and operational problems, ultimately ruining a good design through cost-cutting measures.

This guide details a comprehensive barrel autopsy procedure for an AR-15, as demonstrated by Chad Albrecht from School of the American Rifle. It covers essential checks including thread runout, material verification, erosion gauging, straightness, gas port alignment, and headspace. The critical step involves using a borescope to identify manufacturing defects, such as the smoothbore condition found in the featured Ballistic Advantage barrel, emphasizing the importance of thorough inspection regardless of brand reputation.

This video identifies the top five reasons semi-automatic pistols malfunction or jam. The instructor, drawing from personal experience, details issues like underpowered ammunition, insufficient lubrication, a dirty firearm, improper grip (limp wristing), and manufacturing defects. He emphasizes regular cleaning and proper handling to ensure reliability.

This YouTube video features an "autopsy" or detailed examination of two Triarc Systems Bolt Carrier Groups (BCGs). The video title and description strongly suggest a critical look at the components. A comment reply from TRIARC Systems, LLC acknowledges the issues presented and states they will be addressed, inviting other users with similar experiences to reach out. This indicates a focus on product quality, potential defects, and customer service within the firearms industry.

This video details the catastrophic manufacturing failures that plagued the early production of the L96A1 sniper rifle by Pylon Industries for Accuracy International. It highlights critical defects like improperly machined bolt lugs and the use of incorrect materials, leading to dangerous malfunctions and injuries. The narrative emphasizes how these issues forced AI to develop its own manufacturing capabilities, ultimately establishing the company as a premier precision rifle maker.

This video provides a detailed physical inspection of two Salient Arms International Bolt Carrier Groups (BCGs). The instructor, with clear expertise in firearm components, meticulously gauges and examines various aspects of the BCGs, including headspace, extractor fit, gas key dimensions, firing pin protrusion, and internal finish. Several issues are identified, such as oversized gas keys, potential extractor problems, a failed firing pin hole gauge, and significant internal machining marks, highlighting potential quality control concerns with these specific units.
