What is the purpose of the magazine follower?

• A. It seals the magazine to prevent dirt entry.
• B. It pushes rounds upward to feed into the chamber.
• C. It locks the magazine in place.
• D. It filters debris from spent cases.

Answer: (B)

The thing this question is testing is how a magazine keeps rounds coming up so the firearm can cycle. The follower sits on top of the magazine spring and pushes the stack of rounds upward. As you load rounds, the spring presses against the follower, which drives each round toward the feed lips. When the gun cycles, the bolt strips the top round from the magazine and chambers it, and the follower pushes the remaining rounds up to repeat the cycle. This keeps reliable feeding and helps align the rounds with the feed lips.

The other ideas aren’t the follower’s job. Sealing against dirt is handled by the magazine body and seals or dust covers, not the follower. Locking the magazine in place is the function of the magazine catch, not the follower. Filtering debris from spent cases isn’t performed by the follower either; that’s part of the mechanical handling in the chamber and related components.
