Wilson Combat - AR-15 Upper Disassembly

This expert guide from School of the American Rifle details how to identify and replace a malformed weld spring in an AR-15's delta ring assembly. A misaligned weld spring can cause gas tube issues, leading to potential component damage. The video provides a clear visual comparison and step-by-step instructions for replacement, emphasizing proper alignment for optimal function.

This guide addresses a critical quality control issue identified by Shortshot Tony on a new Daniel Defense Mk18 upper receiver: a loose barrel nut. The video demonstrates how a hand-tight barrel nut leads to significant rail wobble. It highlights the importance of proper torque for AR-15 assembly and compares this failure to lower-tier brands, emphasizing the need for robust quality control even on premium components.

This guide details the process of lapping an AR-15 receiver to ensure proper barrel alignment for improved long-range accuracy. Instructor Stephen Caleb from Brownells explains that receiver faces can be slightly out of alignment, leading to barrel runout. The process involves using a specialized lapping fixture and aluminum oxide lapping compound with a drill to create a perfectly flat receiver face. This ensures the barrel seats flush and square, critical for precision shooting beyond 500 yards.

This expert-level guide details the step-by-step disassembly of the Ruger 10/22 rifle, as demonstrated by a Ruger firearms instructor. It emphasizes crucial safety precautions, lists the necessary tools (a 5/32 Allen key and a small punch), and walks through removing the action screw, separating the stock, and disassembling the receiver components. This procedure is essential for proper cleaning and maintenance of the popular .22 LR rifle.

This guide details the field stripping and reassembly process for the Browning Model 1910 pistol. It covers the unique barrel bushing removal mechanism, recoil spring assembly, and the steps to separate and rejoin the slide, barrel, and frame. The process highlights the pistol's blowback design and John Browning's engineering.

This guide details the field stripping process for the Smith & Wesson M&P 22X, as demonstrated by an expert firearm reviewer. It covers the essential steps for safe disassembly, cleaning, lubrication, and reassembly, highlighting the fixed barrel design common to this class of .22LR pistols. The process is presented with a strong emphasis on safety protocols, crucial for any firearm maintenance.

This guide details the dangers of 'thumbing the hammer down' on a loaded firearm, a technique strongly advised against by experts. It emphasizes that this action, which involves pulling the trigger while manually lowering the hammer, carries a high risk of accidental discharge if the thumb slips. The expert instruction highlights safer alternatives like engaging the manual safety for 'cocked and locked' carry or clearing the chamber entirely.

This guide details the advanced technique of hand stippling a 1911 firearm frame for enhanced grip, as demonstrated by a master gunsmith. It covers the precise application of texture using a punch and hammer, followed by meticulous filing to refine the edges. This process requires significant skill and attention to detail for a professional finish.

This guide details the proper technique for cycling the slide on a semi-automatic pistol, specifically the 1911, as explained by Ken Hackathorn. It emphasizes avoiding "gun abuse" by not slamming the slide on an empty chamber, which can cause premature wear. The explanation includes the mechanical reasons behind this, focusing on how the cartridge rim stabilizes the extractor and cushions the slide's action.

Massad Ayoob, a renowned firearms instructor and legal expert, details the critical post-Defensive Gun Use (DGU) protocol. He emphasizes that the most common mistake is failing to immediately call 911 after a DGU, even if no shots were fired. This action is crucial for establishing oneself as the victim complainant in the ensuing legal aftermath.
