Question: After cleaning a firearm, what is a crucial step to prevent rust and ensure proper function without over-lubricating?

Answer options: ✅ Apply a thin, even coat of appropriate lubricant to all metal surfaces, then wipe off any excess.

  • Submerge all small components in a bath of general-purpose oil for several hours.
  • Leave all components completely dry to avoid attracting dust and debris.
  • Apply a thick layer of grease to the bore and chamber to protect against moisture.

Correct answer: Apply a thin, even coat of appropriate lubricant to all metal surfaces, then wipe off any excess.

Explanation: Proper lubrication post-cleaning is essential for a firearm's longevity and reliable operation. A thin coat protects against corrosion and reduces friction, while excess lubricant can attract dirt or impede function, as emphasized in maintenance guidelines.
