This guide details the use of the Obsidian Arms Bolt Assembly/Disassembly Tool for AR-15, AR-10, and SR-25 platforms. The tool features dual knockout holes, beneficial for stubborn or damaged roll pins, unlike single-hole designs. It includes a roll pin holder and punch. The video emphasizes using a stable wood bench block for striking and a flat-face punch for final pin seating to prevent damage. Instruction is provided by Chad Albrecht, a recognized expert in AR technical maintenance.
This guide details the proper techniques for assembling AR-15 upper receivers, emphasizing the correct tool selection to prevent damage. Instructor Chad Albrecht of School of the American Rifle highlights the critical importance of using tools that engage both the upper receiver and barrel extension for barrel nut installation, and barrel-holding tools for muzzle device work. Improper tool usage can lead to catastrophic failures like sheared index pins and unthreaded barrel extensions.
This video provides a technical autopsy of two Palmetto State Armory AR-15 upper receivers, led by Chad Albrecht of the School of the American Rifle. The process involves detailed checks of torque, barrel extension clocking, sight alignment, muzzle device timing, and gas system function. Live fire testing confirms reliable cycling and bolt lock, with minor issues like extractor springs noted but deemed acceptable for the units' intended purpose.
This expert guide details the meticulous inspection process for PSA AR-15 upper receivers, led by Chad Albrecht of School of the American Rifle. It covers critical measurements like muzzle device torque, barrel concentricity, gas port size, and BCG dimensions, utilizing specialized tools to assess build quality and potential issues like over-gassing. The assessment provides a B- grade for PSA uppers, deeming them decent for their price point despite noted deviations from Mil-Spec standards.
This episode features an interview with Chad Albrecht, founder of School of the American Rifle (SOTAR). Albrecht is a Master Gunsmith, AR-15 Armorer, and Technical Instructor. The discussion centers on the popular and modular direct-impingement AR-15 rifle. Links to SOTAR's website and Instagram, as well as the podcast host's websites (SOLGW and GreenDragonTrading.co), are provided.
This product spotlight by Brownells Gun Tech Caleb focuses on the SOTAR Cam Pin (SCP) from Forward Controls Design. Developed in conjunction with Chad Albrecht of the School of the American Rifle (SOTAR), this upgraded AR-15 cam pin features a unique dimple for consistent indexing during Bolt Carrier Group (BCG) reassembly. This consistent orientation promotes even wear on the cam pin, extending its service life and, consequently, the overall lifespan of the BCG by preventing accelerated wear on other components. The video highlights the importance of this seemingly small part in maintaining the reliability and longevity of an AR-15.
This guide details a comprehensive barrel autopsy procedure for an AR-15, as demonstrated by Chad Albrecht from School of the American Rifle. It covers essential checks including thread runout, material verification, erosion gauging, straightness, gas port alignment, and headspace. The critical step involves using a borescope to identify manufacturing defects, such as the smoothbore condition found in the featured Ballistic Advantage barrel, emphasizing the importance of thorough inspection regardless of brand reputation.
This guide, presented by Chad Albrecht of School of the American Rifle, details the proper technique for using bore snakes on an AR-15 to prevent damage. It emphasizes inspecting bore snakes for wear, replacing them regularly, and pulling them straight through the barrel to avoid damaging the crown, which can degrade accuracy. The expert instructor highlights common issues seen in older rifles due to improper cleaning techniques.
This guide, presented by Chad Albrecht of School of the American Rifle, details the proper cleaning of an AR15 Bolt Carrier Group (BCG). It emphasizes avoiding aggressive scraping tools that can damage critical dimensions, instead recommending chemical solvents and non-abrasive tools like cotton swabs and nylon brushes. Proper lubrication is highlighted as more critical than extreme cleanliness for maintaining the BCG's function.
This guide details a comprehensive barrel autopsy performed by Chad Albrecht of the School of the American Rifle. It covers the methodology for inspecting a Rosco Manufacturing 10.5-inch Nitride barrel after 26,750 rounds of full-auto fire, focusing on identifying wear points like muzzle erosion, throat erosion, and gas port wear that impact accuracy. The process utilizes specialized gauging tools for objective analysis.
This guide details how to fix a carbon-locked adjustable gas block on an AR-15, as demonstrated by Chad Albrecht of School of the American Rifle. It involves a multi-day chemical soak, mechanical shock, meticulous cleaning of components, inspection for gas erosion, and reassembly. The process emphasizes thorough cleaning and proper reassembly to restore functionality.
