Paulo, a vice is not necessary.

Lay the rear of the lower receiver on a block of wood (1X2) and using a modified screwdriver blade and hammer, stake the castle nut.

Here’s a pic of my DIY staking tool.

- Old flat-tip screwdriver blade, removed from the plastic handle.
- Tip was ground down wider to produce a suitable stake indentation.
- Refinished with G96 Cold Blue and lightly coated with CLP to protect the surface from rust during storage.
