Question 3

What does a 'field strip' of a firearm typically involve?

Accepted Answer

Disassembling the firearm into its major components for routine cleaning without special tools

Question 4

Why should a GSI instructor emphasize that students always clean firearms in a well-ventilated area?

Accepted Answer

To avoid inhaling harmful vapors from solvents and lead particles

Answer

Cleaning solvents emit harmful chemical vapors and lead residue from fired rounds can become airborne, so ventilation is critical to protect the cleaner's health.

Question 5

What is the purpose of applying gun oil or lubricant after cleaning a firearm?

Accepted Answer

To reduce friction between moving parts and protect metal surfaces from corrosion

Answer

Lubricants reduce friction and wear on metal-to-metal contact points and form a protective film that prevents rust and corrosion on the firearm's surfaces.
