CRFSC Major Parts and Actions 4

Question 1

Which component on a break-action shotgun secures the barrels to the receiver and is released to open the action?

Accepted Answer

The top lever (or top break lever)

Answer

The top lever operates a locking bolt that engages the barrel lumps; pressing it to the side releases the barrels so the action can pivot open.

Question 2

What is the difference between a single-stack and a double-stack (staggered) pistol magazine?

Accepted Answer

Single-stack holds rounds in a straight column; double-stack staggers rounds in two columns for higher capacity

Answer

Single-stack magazines stack cartridges directly on top of one another in a single column; double-stack magazines stagger rounds in two offset columns, increasing capacity while only moderately widening the grip.

Question 3

On a rifle or shotgun, what is the function of the stock's pistol grip (when present)?

Accepted Answer

It provides a secure hand position for trigger finger control and firearm retention

Answer

A pistol grip provides a near-vertical hand position that improves trigger control, reduces wrist strain, and aids in retaining the firearm during recoil.

Question 4

What is the purpose of a recoil pad on a rifle or shotgun stock?

Accepted Answer

To absorb and distribute recoil energy to reduce felt recoil at the shooter's shoulder

Answer

A recoil pad made of rubber or similar material compresses during recoil, spreading the impulse over a longer time and larger area to reduce the felt impact on the shooter's shoulder.

Question 5

In a semi-automatic firearm, what prevents the action from cycling (and the gun from firing) if the magazine is not fully seated?

Accepted Answer

The magazine disconnect safety

Answer

A magazine disconnect safety blocks the trigger or sear linkage unless a fully inserted magazine depresses the disconnect mechanism, preventing fire without a seated magazine.
