Attachment Methods for AR Gas Block/FSB

This video provides a comprehensive overview of AR-15 gas blocks, explaining their critical role in the direct impingement system. It details standard block types, attachment methods (set screw vs. clamp-on), barrel diameter considerations (0.625", 0.75", 0.93"), and the importance of proper fit to avoid rail interference. The guide also covers adjustable gas blocks for tuning recoil and suppressor performance, while cautioning they add potential failure points.

This guide addresses the myth of needing to pin an AR-15 gas block. While pinning offers superior durability, clamp-on or set-screw gas blocks are more modular and easier for home builders. The video demonstrates using set screws with a dimpled barrel for secure installation, with an option for pinning as an extra layer of security.

This guide details common issues encountered with budget AR-15 platforms, focusing on potential malfunctions and their causes. It covers gas port size and alignment, feed ramp issues, magazine catch installation, safety selector spring failures, broken forward assist assemblies, leaking gas keys, worn gas rings, and improperly machined bolt lugs. The information is presented from personal experience to help owners troubleshoot their firearms.

This guide details the proper installation of AR-15 gas blocks that utilize set screws. It emphasizes the importance of barrel dimples for secure mounting and compares the effectiveness of knurled tip versus cup tip set screws. Proper thread locker selection and application are crucial for preventing loosening and ensuring consistent firearm performance.

This guide details expert techniques for removing various threadlocking compounds from firearm fasteners, as demonstrated by Dave Timm. It covers strategies for low, medium, and high-strength threadlockers, including chemical de-bonders and heat application, emphasizing the importance of identifying the correct compound for effective removal. Instruction is provided by a recognized instructor from Guns & Tactics.

This video offers a highly critical, historically grounded analysis of the M14 rifle's shortcomings, attributing its failure to flawed US Ordnance Corps decisions regarding cartridge standardization and weapon design. The speaker, an expert in small arms, details how political motivations and resistance to innovation led to the adoption of an inadequate weapon system, contrasting it with superior alternatives like the AR-10 and FN FAL. The analysis highlights the detrimental impact of these decisions on US military effectiveness, particularly in Vietnam.

This expert-level entry details the M16's troubled introduction in Vietnam, debunking myths of inherent design flaws. It highlights how political decisions, procurement issues, and ammunition choices, rather than the core design by Eugene Stoner, led to early reliability problems. The entry emphasizes the mechanical evolution from the AR-15 to the M16A1 and the critical role of chrome lining, proper maintenance, and correct ammunition in establishing the platform's eventual success.

This guide, drawing on the expertise of a former Colt employee and AR-15 SME Hank Tatro, details the critical role of AR-15/M16 buffers. It explains how buffer design evolved to manage bolt carrier bounce caused by increased firing rates and different ammunition types. The guide emphasizes selecting the correct buffer for specific firearm configurations and warns against improper mixing and matching, particularly for duty applications. It covers standard rifle and carbine buffers, as well as H, H2, H3, and specialized 9mm buffers, providing insights into their construction and application.

This comprehensive review by Chris Bartocci, a recognized expert with extensive military armory experience, debunks common myths surrounding the Beretta M9/92FS. Bartocci details the pistol's history, including its selection over the M1911, and addresses controversies like slide failures, attributing them to ammunition and high usage rather than design flaws. He highlights the evolution of critical components like the locking block and discusses magazine reliability issues, offering practical insights for owners and enthusiasts.
