Explanation:
The part of a modern firearm that performs the same function as the lock on a muzzleloader is the firing mechanism. In both cases, these components function to initiate the sequence that propels the projectile from the weapon. In a muzzleloader, the lock strikes the primer, igniting the powder, and causing the minié ball to be fired off.
