Add this gun to game, im lazy to write bc all what i wrote was deleted. Link: https://en.wikipedia.org/wiki/StG_44.
Mag capacity: 30 rounds
Caliber 7.92x33mm Kurtz

Damage: 1-16 blocks: 15 per mag, 16-32 blocks: 12.5 per mag, 32-48 blocks: 10 per mag, 48 and more will have 7.5 damage per mag. All damage is to full prot diamond armor, like in wiki. No effects included.
Crafting cost: 2 redstone alloy ingots, 1 steel plate, 2 damascus steel ingots and 1 stripped oak log. Damage and cost of crafting can vary for balance.
Ammo crafting: 6 mags can be crafted by using: 4-6 7.92x57 mauser ammo and 2 steel ingots.
Reload can be 2 secs.
Velocity can be the same with Madsen

Here we will compare it with madsen: StG 44 will have better dmg at close ranges but drop at long ranges, mag capacity is same, but cost of crafting gun and ammo is higher.
Thats all, comment
