Law Tactical Gen-S Folder

In this video, Caleb breaks down the LAW Tactical Gen S Sidefolder for the AR-15 and walks through a full swap from a Gen 3M folding adapter to the new Gen S. You will see the profile and material differences, what changed in the latch housing, how the new flange design adds contact area, and how to install and tension the system correctly. This is a true bench install. Caleb uses the LAW lower alignment tool with a Geissele reaction block to keep the receiver extension perfectly aligned while torquing and staking the castle nut. Along the way, he covers the correct order of operations, what not to overtighten, where thread treatment belongs, and why pulling the system forward and keeping tension correct matters for long-term reliability.
