Radical Firearms AR-15 Issues - Broken Bolt

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 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 demonstrates the CompMag, a fixed magazine solution for AR-15 style rifles designed to comply with restrictive firearm laws, particularly in California. It details the unique side-loading process for up to 10 rounds and provides a clear method for clearing double feed malfunctions by locking the bolt back and clearing through the ejection port.

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.

The description emphasizes the educational purpose of the video, with the creator's views representing their own experiences. It also includes various promotional links for the channel, social media, and affiliate sponsors like Werkz Holster and Gatorz Glasses. The video aims to provide insights into the topic of gun control, with Nugent's commentary highlighted as significant.

This two-year, 8,000-round review of a PSA 10.5" AR-15 pistol reveals significant issues with quality control and durability. While some components like the SB Tactical brace and Rise Armament trigger performed well, the factory bolt carrier group and barrel showed premature wear. A major manufacturing defect in the lower receiver required modification. The speaker concludes PSA is a hobbyist brand requiring extensive user QC for high-volume use.

This video demonstrates how to securely attach a knife to MOLLE webbing using paracord. It highlights the importance of using Kydex or plastic sheaths with rivet holes for reliable mounting, explaining why softer materials like nylon or leather are less suitable. The tutorial covers preparing paracord and employing a 'boot lacing' technique for a stable attachment, offering advice on optimal placement on gear for functionality and comfort.

This review covers a Palmetto State Armory 10.5" AR pistol build, highlighting its components like the SBA-3 brace and PSA flash can. Despite an initial assembly issue with the buffer tube, the firearm proved reliable after 300 rounds with zero malfunctions, using various magazines and Wolf steel-case ammo. The light recoil and PSA polished trigger contribute to good controllability.
