CRFSC Firearm Maintenance and Cleaning 2 — Questions and Answers
Question 1: What part of a semi-automatic pistol should be inspected for cracks during routine maintenance?
- Only the grip panels
- The frame, slide, and barrel (Correct answer)
- Only the magazine
- Only the trigger
Correct answer: The frame, slide, and barrel
The frame, slide, and barrel are structural components that bear firing stress and must be inspected for cracks that could cause failure.
Question 2: Which area of a bolt-action rifle requires lubrication to ensure smooth cycling?
- The trigger guard only
- The bolt body and its locking lugs (Correct answer)
- The stock inlet only
- The muzzle crown
Correct answer: The bolt body and its locking lugs
The bolt body and locking lugs must be lightly lubricated to ensure smooth operation and reliable lock-up.
Question 3: What is the risk of over-lubricating a firearm stored in cold temperatures?
- The oil expands and cracks the barrel
- Oil can thicken or congeal, slowing or preventing the action from cycling (Correct answer)
- Cold oil evaporates too quickly
- Lubrication becomes toxic in cold conditions
Correct answer: Oil can thicken or congeal, slowing or preventing the action from cycling
In cold weather, thick or congealed oil can impede moving parts, potentially causing a failure to fire or cycle.
Question 4: What is a bore snake used for during firearm maintenance?
- Measuring barrel length
- Quickly cleaning the barrel bore in the field (Correct answer)
- Checking headspace
- Removing stuck casings
Correct answer: Quickly cleaning the barrel bore in the field
A bore snake is a one-pass cleaning tool that threads through the barrel to remove fouling quickly, especially in field conditions.
Question 5: Why is it important to check a firearm's magazine for debris during cleaning?
- Debris in the magazine can cause feeding malfunctions (Correct answer)
- Debris changes the weight of the magazine
- A dirty magazine voids the firearm's warranty
- Debris affects the magazine spring color
Correct answer: Debris in the magazine can cause feeding malfunctions
Dirt, debris, or grit inside a magazine can prevent rounds from feeding properly into the chamber, causing a malfunction.
Question 6: After cleaning a restricted handgun, what should you do before reassembling to verify function?
- Load it and test fire
- Perform a function check with an unloaded firearm (Correct answer)
- Store it immediately
- Apply extra oil to all parts
Correct answer: Perform a function check with an unloaded firearm
A function check on an unloaded firearm confirms the action, trigger, and safety mechanisms are working correctly after reassembly.
