This guide details the installation of the CMMG ZEROED Adjustable Gas Block. It emphasizes pre-installation steps like securing the barrel nut and aligning the gas tube. The process involves sliding the gas block onto the barrel, aligning set screws with barrel recesses, and securing them. Proper alignment is crucial for optimal gas system function and is indicated by the flushness of the set screws.

This video demonstrates a common issue encountered during gas block installation: shallow or improperly tapped threads on the set screw holes. The instructor from School of the American Rifle shows how to identify this problem, where the set screw doesn't fully seat, leading to a false torque reading. A practical solution involving running a tap through the holes to clean and deepen the threads is presented as a quick fix, emphasizing that this is a common gunsmithing task rather than a reason to return a part.

This guide details a method for installing low-profile AR-15 gas blocks using a thumb screw for initial alignment and a borescope for precise gas port alignment. It emphasizes the importance of set screws with teeth for better grip and provides torque recommendations for thread lockers like Rocksett and high-temperature red Loctite.

This video from School of the American Rifle discusses the proper application of high-temperature thread lockers like Rocksett and Hot Lock for firearm components. It emphasizes using these products for areas exposed to significant heat, such as muzzle devices and suppressor mounts, to ensure they remain secure. The instructor advises against using standard blue thread locker in these applications due to its lower temperature rating.

This guide details the installation and tuning process for the EC Tuner, a precision rifle accessory designed by Erik Cortina for .22LR firearms. It covers component identification, secure installation using specific tools, and the critical hand-adjustment technique for optimizing barrel harmonics to achieve smaller group sizes. The process emphasizes precise tensioning of set screws for repeatable performance.

This guide, presented by a Brownells technical expert, details the proper installation and alignment of an AR-15 gas block. It emphasizes the importance of aligning the oversized gas block port with the barrel's gas port, discussing tolerances and the common practice of dimpling the barrel for set screw indexing. The expert recommends dimpling only the rear screw to accommodate variations between manufacturers.

This video details the Warren Tactical Series sight sets designed for Glocks. These sights are constructed from steel for durability and fast target acquisition, favored by competitive shooters and law enforcement. They are engineered to fit factory dovetails with minimal fitting and offer various front sight options including plain black, fiber optic (red/green), and tritium for low-light conditions. Rear sights feature a non-serrated face, drift adjustability for windage, and a locking set screw, with radius corners for snag-free holster draws and a U-shaped notch for quick sight alignment.
