Note: some of the tools listed here may not be required and some could be substituted with household items such as 2X4 wood, plywood, thick cloth, leather, plastic, rubber, metal materials, etc.

Tip: Have extra detent pins and you could use a clear plastic bag when you're installing your pivot takedown pin detent pin to prevent it from flying off.
