This video focuses on essential tools and techniques for working with AR-15 upper receivers. It addresses a common concern about lubrication by clarifying that all necessary parts were indeed greased during the demonstration, specifically mentioning Aeroshell 64. The content showcases a variety of specialized tools designed for AR-15 upper receiver assembly and disassembly, aiming to demystify the process and provide viewers with practical knowledge for their builds or maintenance.
This SmythBusters episode tackles five common myths surrounding AR-15 rifle builds. The video debunks misconceptions about using reaction rods, the state of raw aluminum after lapping, gas block alignment, clamping the barrel for muzzle device installation, and the practice of using a torque wrench for barrel nut removal. Key takeaways include alternative methods to reaction rods, the protective benefits of grease on lapped aluminum, the forgiving nature of gas port hole sizing, the acceptability of clamping for muzzle device work, and that torque wrenches are not ruined by barrel nut removal. The video aims to educate viewers and set the record straight on these building practices.
This video addresses a feeding problem encountered with a Sons of Liberty Gun Works East India Upper Receiver during live fire testing. The owner later clarifies that the issue was due to user error during the installation of the rail, specifically attributing it to the "Real Avid lug lock" reaction rod used. The problem led to a feeding malfunction, which has now been identified and resolved by the owner.
This video reviews the Geissele Automatics Reaction Rod, a tool designed for working on AR-15/M-4 style rifles. The presenter explains how the rod securely clamps into a vise and holds the upper receiver by engaging the barrel's star chamber. This method allows for torque to be applied, particularly to muzzle devices, without stressing the aluminum receiver, making it an effective gunsmithing accessory.
