Which item is NOT listed as a contributor to reliable firearm function?

• A. Using heavy greases that attract grit and become gummy
• B. Cleanliness
• C. Regular maintenance
• D. Correct ammunition

Answer: (A)

Reliable firearm function comes from keeping the weapon clean, performing regular maintenance, and using the correct ammunition. Cleanliness prevents powder residue, debris, and fouling from building up and causing jams or misfeeds. Regular maintenance keeps springs, pins, and moving parts within their designed tolerances, ensuring smooth cycling and consistent performance. Correct ammunition ensures the cartridge dimensions and pressure align with what the firearm was designed to handle, supporting reliable operation and safe function. The thing that does not contribute to reliability is using heavy greases that attract grit and become gummy; this actually hinders function by trapping dirt and carbon and turning sticky, which can cause parts to stick or fail to cycle.
