I think there might be a way for gunpowder arms to beat the Magical Armor Corps. Kazuya is still thinking in terms of the ancient arquebus. Since he's a student of social economics, he probably doesn't know of the huge advancements of modern firearms nor engineering.

First of all, the arquebus is a smoothbore musket that relies on the old black powder, firing an ordinary lead ball. As a result, its range, accuracy and muzzle velocity isn't all that great. Now a rifle with grooved rifling in the barrel, a modern-day cartridge and improved gunpowder gives a much higher punching power at a longer range. The grooves stabilize the bullet in flight, and because of the improved gunpowder and better bullet ballistics, we have something that can do a lot more damage.

Now the Magical Armor Corps has armor plate that blocks all magical attacks. However a bullet fired at a higher velocity and kinetic energy HAS NO MAGIC. Therefore the barrier won't stop it. Furthermore, the armor of the Corps might have damage reduction effects, BUT that's against more primitive means such as an arrow or stone, which are fired at lower velocities and kinetic energy. A bullet fired at tremendous velocity may be able to overcome it.

Say for example the reduction effect is 20%. An arrow fired at the armor at about 100 feet/second gives a force of around 6 foot pounds so it gets reduced to 4.8 foot pounds. Against an armor plate of about 3 millimeters will cause the arrow to bounce off. Now compare that to a 30-06 armor-piercing bullet of an M1 Garand Rifle. That's over 2,750 foot pounds. Twenty percent reduction gives us a force of 2,200 foot pounds.

The bullet still punches through 3 mm of armor. We have a dead knight. The magical ability of the Magical Armor Corps can only go so far, and the Barrett 50 sniper rifle would be an ideal weapon to take them out.
