Question 3: What is the primary purpose of lubricating a firearm after cleaning?
- To improve accuracy
- To reduce friction and prevent corrosion on metal parts (Correct answer)
- To increase muzzle velocity
- To add weight for stability
Correct answer: To reduce friction and prevent corrosion on metal parts
Lubrication reduces wear on moving parts and creates a protective barrier against moisture-induced corrosion.
Question 4: Before cleaning a firearm, what is the mandatory first step?
- Remove the stock
- Ensure the firearm is unloaded and action is open (Correct answer)
- Apply solvent to the barrel
- Disassemble the trigger group

- Compressed air canister
Correct answer: Cleaning rod with patch holder
A cleaning rod fitted with a patch holder allows you to run solvent-soaked and dry patches through the bore to clean it.
Question 6: Why should excess oil be wiped off a firearm after lubrication?
- Oil attracts debris and can affect ammunition reliability (Correct answer)
- Oil makes the firearm look unprofessional
- Excess oil increases weight significantly
- Oil corrodes the finish over time
Correct answer: Oil attracts debris and can affect ammunition reliability
Excess oil attracts dirt and debris that can cause malfunctions, and oil in the chamber can affect primer ignition.
