These military type weapons are nothing of the sort. They are effectively "scary" looking, UNDERPOWERED, semi auto, hunting rifles. They do generally hold more ammo than your typical hunting rifle however. These "assault weapons", as they are being called, are usually 5.56mm caliber. The 5.56mm caliber was adopted by military orgs around the word specifically because it is LESS lethal than the 7.62mm caliber it replaced. The 30-30 (which is generally thought of as the minimum caliber for deer hunting) has almost twice as much energy.
