Before cleaning a firearm, what is the most critical first step?
Answer: Perform the PROVE procedure to ensure the firearm is completely unloaded
The PROVE procedure must always be performed first to confirm the firearm is empty. Many accidental discharges during cleaning result from failures to verify the firearm is unloaded.
What is the purpose of applying a thin coat of gun oil after cleaning a firearm?
Answer: To prevent rust and corrosion and to lubricate moving parts for reliable operation
A thin coat of gun oil after cleaning protects metal surfaces from moisture and corrosion and ensures moving parts operate smoothly and reliably.
What is a bore brush used for during firearm cleaning?
Answer: To scrub fouling and lead or copper deposits from the inside of the barrel
A bore brush, typically made of bronze or nylon, is pushed through the barrel to scrub out fouling, lead deposits, and copper jacket residue left by fired bullets.
When field-stripping a semi-automatic pistol for cleaning, what component is typically removed first?
Answer: The magazine, after verifying the firearm is unloaded
The magazine must be removed first, followed by verifying the chamber is empty. This is the mandatory first step before field-stripping any semi-automatic pistol.
How should solvent-soaked cleaning patches be disposed of after cleaning firearms?
Answer: Allow them to dry fully in a ventilated area and then dispose of in a waste bin
Solvent-soaked patches should be allowed to fully dry in a ventilated area before disposal. Some solvents are flammable or produce fumes, making enclosed storage of soaked patches a fire risk.
What is leading in a firearm barrel and how is it addressed during cleaning?
Answer: Lead deposits from fired bullets that accumulate in the barrel and require a bronze brush or lead-removing solvent to remove
Leading refers to lead deposits left by unjacketed lead bullets. It degrades accuracy and can increase chamber pressure if severe. Bronze brushes and lead-removing solvents are used to clear it.
