FSC Firearm Cleaning and Maintenance 2

Question 1

Over-lubricating a firearm with too much oil can cause which problem?

Accepted Answer

Attract dirt and debris, potentially causing malfunctions

Answer

Excess oil acts like a magnet for grit and carbon, which can accumulate in critical areas and lead to feeding or cycling failures.

Question 2

Why is it important to wear eye protection when cleaning a firearm?

Accepted Answer

Solvents and debris can splash or flake off and injure eyes

Answer

Chemical solvents can splash, and bore brushing can dislodge metal fragments or fouling particles that could injure unprotected eyes.

Question 3

What should you do if you discover a bulge or crack in a firearm's barrel during cleaning?

Accepted Answer

Stop using the firearm and have it inspected by a qualified gunsmith

Answer

A bulged or cracked barrel is a serious structural defect that can cause the firearm to catastrophically fail when fired, and only a gunsmith can safely evaluate it.

Question 4

When using a cleaning rod, in which direction should you push the patch through the barrel for best results?

Accepted Answer

From the chamber (breech) end toward the muzzle

Answer

Pushing from the chamber toward the muzzle follows the direction of the bullet, pushes fouling out the muzzle end, and avoids bending the cleaning rod against the crown.

Question 5

Which parts of a semi-automatic pistol typically require lubrication during routine cleaning?

Accepted Answer

The slide rails, barrel exterior, and trigger group contact points

Answer

Slide rails, the barrel's exterior locking surfaces, and the trigger group are the primary friction points that require light lubrication for reliable cycling.
