Minigun!

The Laser Minigun is an unbreakable, rapid-fire hitscan ranged weapon that uses arrows as ammo and fires instant laser shots with a visible particle beam and impact effects that stop at solid blocks and do no melee damage; each laser hit now deals 2 damage. Hold right-click to begin firing immediately and continuously (it fires an instant shot on start and will keep firing while held; release to stop); it has a very high fire rate with randomized spread that increases with range, is compatible with bow enchantments, and shows a bow-style durability bar while taking no durability damage, and mobs hit by its shots will recognize the player as the attacker and can become aggressive in response.
