Ballistics Advantage - Barrel Autopsy

This in-depth analysis of an Anderson Manufacturing AR-15 barrel reveals significant quality control issues. Headspace was found to be short, and chamber mapping indicated constrictions causing potential extraction problems. Borescope inspection showed chrome flaking and a poorly machined muzzle crown, despite the barrel being chrome-lined.

This video demonstrates how to properly dimple an AR-15 barrel for a gas block using a BRD Engineering jig. Dimpling ensures the gas block set screws have a secure seating point, preventing movement and maintaining alignment with the gas port. The process involves using a specialized jig to accurately locate and drill the dimples, crucial for reliable firearm function.

This guide details how to effectively remove and prevent barrel corrosion on an AR-15. It emphasizes using a borescope for inspection, Evapo-Rust for rust removal, and specialized bore cleaners for post-soak cleaning. The expert instruction highlights the importance of proper cleaning and the application of protectants to maintain barrel integrity.

This video, titled 'Ballistic Advantage Barrel Autopsy', likely delves into a detailed examination or analysis of a Ballistic Advantage barrel. Given the 'autopsy' theme, the content is expected to involve a technical breakdown, potentially focusing on wear, performance, or manufacturing aspects. Viewers can anticipate an in-depth look at a specific firearm component, suitable for those interested in the intricacies of AR-15 barrels and their performance characteristics.

This guide details how to repurpose a worn AR-15 receiver set into a dedicated .22 LR build, a project undertaken by Hop due to excessive assembly and disassembly. The video highlights the advantages of dedicated .22 LR barrels over conversion kits and showcases specific components like a CMMG barrel and bolt kit, a Ballistic Advantage rail, and a Catch22 bolt catch for enhanced functionality. It also touches on suppressor performance differences for rimfire applications.

This BUILD BOX bonus video focuses on the maintenance of a firearm's Bolt Carrier Group (BCG). Host Chris Cerino demonstrates how to identify when a BCG requires attention, covering procedures like replacing gas rings and performing BCG testing. The episode is sponsored by Aero Precision, Ballistic Advantage, and Stag Arms. BUILD BOX is a DIY firearm show airing on the Outdoor Channel, and viewers are encouraged to enter the Ultimate Builder Giveaway for a chance to win prizes from various firearm brands.

This video details the diagnosis and repair of a feeding issue on a Sons of Liberty Gun Works East India upper receiver. The root cause was identified as a sharp burr on the barrel extension's feed ramp, causing rounds to jam. The solution involved polishing the feed ramps and adding a secondary bevel, replicating Colt's design, which successfully resolved the malfunction.

This video demonstrates the internal mechanics of an AR-15 bolt carrier group using cutaway models. It highlights the importance of internal bore dimensions for gas system efficiency and explains how to diagnose potential issues like gas leaks. The demonstration covers the cycle of operation, critical seals, and common manufacturing defects, offering advanced insights for AR-15 maintenance and troubleshooting.

This video provides a detailed autopsy of a faulty AR-15 Bolt Carrier Group (BCG). The analysis reveals critical manufacturing defects including an undersized bolt tail failing gauges, excessive firing pin protrusion causing pierced primers, an oversized firing pin hole, and an oversized cam pin hole leading to headspace issues. These flaws significantly compromise the BCG's function and reliability.

This video demonstrates a specialized technique for swapping an AR-15 rear takedown pin without full firearm disassembly. It highlights the use of a custom-fabricated tool, often made from a 1/16 inch Allen wrench, to depress the detent. The method allows for efficient pin replacement, particularly useful on rifles with staked castle nuts, by leveraging the old pin to guide the new one into place.
