How to Remove Tie Rod Nut - Ball Joint Nut That Keeps Spinning

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 guide details essential quality control checks for budget or 'blem' AR-15 builds, emphasizing the need for user verification of critical components. Lucas Botkin, an established industry professional, demonstrates the use of specialized tools to ensure proper torque on the barrel nut, gas block, and castle nut, crucial for safety and reliability.

This video demonstrates the use of the Brownells AR-15 Buffer Tube Lower Receiver Fixture for simplifying buffer tube installation. The fixture securely holds the lower receiver via the grip screw and provides an adjustable, self-aligning support for the buffer tube, ensuring vertical alignment during tightening. This tool also offers additional benefits for staking the castle nut and can be used for other receiver tasks like installing pins and the grip.

This guide details the installation of the Sylvan Arms SA 5 Pro Folding Stock Adapter on an AR-15 or AR-10 platform. The process involves threading the adapter onto the receiver, securing it with set screws, and attaching the buffer tube. The video highlights this as a potentially more cost-effective alternative to the Law Tactical Folding Adapter, offering a step-by-step demonstration suitable for intermediate DIY gunsmiths.

This guide details the installation of the BCM Buffer System on an AR-15 platform. It covers the proper threading of the buffer tube, installation of the buffer retainer and spring, securing the end plate, and final insertion of the buffer and spring. The process emphasizes correct alignment and tension to ensure reliable function.

This guide details the use of the Suns of Liberty Gunworks Armorer Punch Set for AR-15 maintenance and installation. It covers specialized tools for pivot pin installation, various roll pin punches for different sizes, a unique bolt catch punch designed to protect receiver finish, starter punches for easier roll pin insertion, larger punches for stubborn pins, and 50°/40° staking punches for gas keys and castle nuts. The punches are constructed from heat-treated tool steel with a nitride coating.

This video from Buckeye Ballistics provides a practical, albeit unconventional, comparison of five common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) by shooting watermelons. The expert demonstrates varying levels of terminal performance, from the .22LR's significant splitting to the .45 ACP's complete watermelon fragmentation, highlighting the differences in hydraulic shock and expansion. The test utilizes specific hollow-point ammunition, including Speer Gold Dot, Aguila Super Maximum, and Underwood XTP, showcasing their effects.

This video provides a practical, safety-conscious comparison of common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) against concrete blocks. The host, demonstrating high authority and expertise, details the testing methodology and results, emphasizing the risks of ricochet. None of the tested pistol calibers fully penetrated the concrete block's second wall, suggesting their limitations for certain penetration scenarios.

This review of the Taurus TX22 .22 LR pistol details its features, including a 16+1 capacity and excellent trigger. While initial testing with CCI Mini-Mags was flawless, subsequent tests with various ammunition types revealed cycling issues and culminated in a catastrophic failure. The failure was attributed to a squib load followed by a second shot, causing a barrel bulge and ruptured casing, highlighting potential ammunition inconsistencies. The review provides a detailed look at disassembly and damage assessment.

This video from Buckeye Ballistics provides an experimental comparison of three popular rimfire calibers: .22LR, .22WMR, and .17HMR, using cantaloupes as ballistic mediums. The host, an experienced shooter, demonstrates the distinct terminal ballistics of each round, highlighting how bullet construction and velocity affect target interaction. The comparison offers practical insights into the performance differences between these rimfire cartridges on soft tissue simulants.
