Geissele Automatics Reaction Rod
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.
