This video delves into the AR-15 "anti-walk" versus "anti-rotation" pin controversy, distinguishing their functions and addressing common misconceptions. Caleb and Brownells Gun Tech Steve clarify that anti-walk pins are essential for certain aftermarket cassette-style triggers, preventing pins from walking out due to the absence of a standard hammer spring. Anti-rotation pins, on the other hand, are designed to prevent pin rotation, which theoretically mitigates wear on receiver holes over extensive use, though the video suggests this is often a solution to operator error. The discussion also covers pin breakage, attributing it to firearm issues like overgassing rather than pin design, and reassures viewers that incorrect pins likely won't cause problems until significant round counts are reached.
This February 2023 Q&A features the InRange TV channel collaborating with Print Shoot Repeat (PSR). The discussion covers a wide range of topics, primarily focusing on 3D printing in the context of firearms. Key areas explored include potential issues with YouTube, the feasibility of using printed guns in competitive matches like Brutality, aftermarket improvements for VHS2, and the possibility of 3D printing a PS90. They also delve into 3D printed fire control groups (FCGs), barrel harmonic tuning devices, recommendations for 3D printers, the future of 3D printing materials and designs, and design weaknesses like layer lines. Other topics include alternative DIY hobbies, the development of reliable 3D printed cartridge cases, tips for printing magazines, ECM barrels, whether PSR has printed anything concerning to shoot, the advantages of 3D printing over molds, favorite printed gun designs, DIY tools and accessories for the gun community, utilizing unique 3D printing shape capabilities, and a comparison of the impact of 3D printed guns versus suicide drones on the future of conflict.
This YouTube video provides a detailed guide on how to remove and install the Fire Control Group (FCG) on an AK-variant rifle. The demonstration specifically involves replacing the factory Arsenal trigger with a Tapco G2 trigger. The description also includes a link for viewers interested in purchasing firearm-related items.
