Not exactly. You can own fully automatic “machine guns” here, but you have to purchase an exorbitantly priced tax stamp. There are special triggers you can add to your AR-15 that allow full auto via legal loopholes. But they’re banned on a regular basis after the ATF catches wind. Your best chance at hearing a machine gun sound is at a car meet up where the young hoodlums have aggressive pop tunes (explosions bang and pop out of the exhaust) or at a shooting range that rents out actually fully automatic rifles.
