...including the super destructive .50-caliber sniper rifle, which an 18-year-old can easily buy in many places...

If the 18 yr old has $8,000 bucks to drop on the rifle and $6 bucks a round for the ammo.

The rifle is expensive, but the ammo is pretty cheap in bulk . . . $1.85 a round . . . if you buy 9,600 rounds for $17,760. I can see an 18 y/o wanting to have one. Isn’t that what credit cards are for?
