3. Pivot the hook side of the tool upwards, and snap it into place around the base of the rear nut.

If your R2-0 is new, the tool should be a very tight fit and should have zero play.

A properly installed R2-0 will secure tightly to your Geissele mount and will not shift or pop off, even under intense recoil.
