No more Hitch Vise slop! (Hitch Vise Part 2)

This video showcases the X-PRT90, a three-position FRT specifically designed for the FN P90 platform. Unlike 3D printed alternatives, the X-PRT90 features robust construction with all-metal components, including stainless steel and aluminum parts. The installation process is aided by an included jig, allowing for integration into the factory P90 trigger group. The speaker emphasizes the durability and quality of the metal construction over plastic alternatives.

This entry details the unique XR-86 custom rifle, a 1986 build by Wilfred Ellis. It masterfully combines components from an M60 (flash hider), an M14 (gas system), and an AR-15 (trigger, bolt, locking system). The AR-15 trigger is notably rotated 90 degrees, and its bolt is integrated with the M14 gas system, showcasing advanced gunsmithing.

This video provides a detailed, step-by-step guide on how to build a Sig P365 X Macro chassis system, incorporating the Radian Afterburner + Ramjet barrel and compensator. The instruction, delivered with clear expertise, covers the disassembly of the original slide, installation of the new barrel assembly, and integration with the chassis and a folding stock. The presenter demonstrates efficient techniques for modular firearm upgrades.

This guide details the installation and operation of the X-PRT90 progressive trigger system for the FN PS90 SBR. The X-PRT90 offers a unique third position that allows for a faster rate of fire by pushing through the trigger pull, effectively creating a legal 'forced reset' malfunction. The video also touches on CMMG barrel modifications and the PS90's unique bottom ejection.

This guide explains how to adjust the trigger weight on a 1911 pistol, specifically addressing a viewer's request to increase a 3lb trigger to 5lbs. The process involves understanding that the 1911's trigger pull is governed by its leaf spring. Adjustments can be made by tuning the existing spring or by replacing it with a pre-tuned spring of the desired weight. The speaker, demonstrating experienced knowledge, emphasizes the importance of proper firearm handling and understanding the mechanism.

This guide, presented by an expert firearms instructor, details the benefits and installation of adjustable triggers for platforms like the AR-15. It covers understanding trigger mechanics, adjusting pull weight, reset, and overtravel, and highlights ideal users for these components. The instruction emphasizes safety and practical application for competition and precision shooting.

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.
