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 comprehensive cleaning process for a heavily fouled Cobalt Kinetics Pro Series AR-15 rifle, emphasizing the use of Radco CLP to break down stubborn carbon buildup. The instructor, Joe, demonstrates a thorough field strip, component cleaning, inspection for potential failure points like the cam pin and bolt, and reassembly. He highlights that while the rifle ran despite extreme neglect, regular cleaning is crucial for reliability, and advocates for a practical approach rather than a spotless deep clean for everyday maintenance.

This guide details how to clean an AR-15/M4/M16 rifle, emphasizing that while these rifles are robust and tolerate some neglect, regular cleaning is essential. Key areas to focus on include the bolt carrier group, chamber, and barrel. The instructor highlights the importance of inspecting critical components like bolt lugs and gas rings, and advises against over-cleaning parts that can lead to wear or out-of-tolerance issues. Proper lubrication of the bolt carrier group is stressed for reliable function.
