Which firearm has a locking system described by rising barrel?

• A. Glock 17
• B. M240B
• C. M16
• D. AK-47

Answer: (A)

The locking system described as rising barrel refers to a tilting-barrel, locked-breech design where the barrel moves in relation to the slide as the pistol cycles. In this setup, the barrel remains locked to the slide during firing, then tilts (rises/downs as it unlocks) to disengage from the slide so the slide can continue rearward. The Glock family uses this distinctive tilting-barrel mechanism with a separate locking block, a hallmark of its operation. Among the given firearms, this locking arrangement is characteristic of the Glock 17, while the others rely on different locking methods (rotating bolts, gas-operated tilting bolts, long-stroke gas pistons, etc.).
