The FN/FAL locking system operates via which mechanism?

Explanation:
Locking the FN/FAL breech is achieved by the bolt being cammed downward so it seats securely in the receiver. As the bolt carrier drives the bolt forward, locking cams push the bolt head down, bringing the bolt’s locking surfaces into contact with the receiver recesses. That downward motion—this lowering of the bolt—lets the bolt lugs engage properly, creating a tight, high-pressure seal and resisting the rearward force of the fired cartridge. This tilting/lowing action is what locks the breech, rather than rotating locking lugs or a swinging lock. When unlocked, the gas system and extractor/ejector components drive the bolt rearward, lifting it out of the recesses to unlock.
