Agreed. Only people with a long history of shooting are qualified. They started with a pea shooter, then went to a sling shot. Then a bow and arrow set all before 10 years old. At 11 years old they should have a BB gun. After 18 years old a 22 rifle.
Then comes the 30-30 Winchester and or the 30-06 by 21 years old. By 25 they should have the hand gun permit and a 22 pistol plus an AR 15. If you can only afford ONE gun? For all uses? Its the AR 15.
AR’s are good for target shooting, plinking, hunting. Ammo is in abundance via military surplus, and cheap because they are small cartages, less material costs. Like a pistol cartridge. Very light projectile too, so very little kick back or recoil. Good for newbie soldiers and small woman shooters too. That’s why they created it. Very light ammo and no kick. Many soldiers never touched a gun. Plus they can carry more rounds per soldier.
Its also good insurance in case the one in a million chance of civil unrest or uprising and you need to protect your life, home, store, or neighbors.
P.S. Same as boats. You never start off with a 30 foot cabin cruiser with one engine. You start with 13 foot Boston Whaler and an 18 hp outboard. Later on an 18-21 foot with a 100-200 hp outboard. Simple shit.
