Best AR15 Receiver Extension/Buffer Tube Jig

This video details a troubleshooting process for an AR-15 experiencing a stuck bolt carrier group. The issue was ultimately identified as an incorrectly sized buffer tube detent that was too long, causing it to catch. The presenter demonstrates the process of identifying the problem, swapping parts, and testing functionality, emphasizing the importance of correct component fit for reliable operation.

This guide details the installation of an AR-15 buffer tube using the LAW Tactical Alignment Tool (LAT) in conjunction with a Geissele Reaction Block. Expert instruction from the School of the American Rifle demonstrates how to achieve perfect alignment of the receiver extension with the lower receiver, crucial for proper function and preventing common assembly errors. The process involves securing the components, torquing the castle nut to 38-42 foot-pounds, and ensuring a reliable build.

This video provides an in-depth look at the Franklin Armory binary trigger system, presented as an alternative for those in states where FRTs are prohibited. The speaker highlights its affordability, especially after recent price drops, and its ability to provide rapid fire capabilities. The installation process is detailed, emphasizing the trigger's dual-mode functionality (semi-automatic and binary) and its potential to enhance range fun, even for new shooters. The speaker, an experienced firearms enthusiast, also touches on other gear like O-site optics and Shellshock ear protection.

This guide details how to address a seized AR-15 upper receiver, a common issue exacerbated by suppressor use and infrequent cleaning. The instructor, with extensive firearms experience, demonstrates a multi-stage approach starting with penetrating oils and progressing to more aggressive chemical cleaners when initial methods fail. The video emphasizes understanding dwell time and the effects of carbon buildup, offering practical solutions for a problem that can render a firearm inoperable.

This clip from the AT3 Tactical Podcast details a cautionary tale about attempting to refinish an AR-15 upper receiver using nail polish, resulting in a poor aesthetic. The discussion highlights common mistakes in firearm customization, such as improper surface preparation and the use of unsuitable materials. It offers advice on proper refinishing techniques, emphasizing cleaning and material selection, and contrasts the failed DIY attempt with professional options like Cerakote. The experience serves as a lesson in firearm modification and the importance of understanding the process before undertaking it.

This guide details the process of replacing the buffer and spring assembly in an AR-15 platform rifle. It covers disassembly, removal of the old components, installation of new parts like the Kynshot RB5000 hydraulic buffer or the Geissele Super 42 system, and reassembly with a function check. The video emphasizes proper technique and the benefits of upgraded components for recoil management and reliability.

This guide details the process of diagnosing and repairing an owner-induced feeding problem in an AR-15 upper receiver, specifically addressing a burr on the barrel extension's feed ramp. Expert gunsmith Chad Albrecht demonstrates meticulous inspection, burr removal, and polishing techniques to restore reliable feeding. The video emphasizes that such modifications, while often overlooked, are valid solutions for specific AR-15 malfunctions.

This guide details a diagnostic technique for AR-15 bolt carrier groups, focusing on efficiency rather than simple pass/fail. Developed by Chad Albrecht of School of the American Rifle, it uses custom gauges and cutaway components to illustrate gas dynamics, critical seals, and potential failure points like gas leaks. This advanced method helps troubleshoot functionality issues and understand the nuances of the AR-15's internal gas system.

This video provides a critical, expert-level inspection of a problematic AR-15 Bolt Carrier Group (BCG) by Chad Albrecht of School of the American Rifle. The analysis details numerous manufacturing defects, including an undersized bolt tail, excessive firing pin protrusion, oversized firing pin and cam pin holes, and a failing headspace check. The content highlights the importance of precision gauging in identifying critical failure points that impact rifle reliability and safety.

This guide details a specialized technique for swapping an AR-15 rear takedown pin without requiring a full disassembly. It leverages insights from Chad Albrecht of School of the American Rifle, emphasizing the use of a modified 1/16 inch Allen wrench or a specialized tool to manage the detent. This method is particularly useful for AR-15 variants with collapsible stocks, offering a more efficient approach to maintenance.
