[Sasparilla]

...The assault rifle was loaded with a 30-round magazine, which had another inverted 30-round magazine taped to it, according to police.

Gee Willikers!
No one ever thought of that before...

If he had a third taped to it it would be 90 rounds if he didn’t fumble the magazine changes.

[T-Bone Texan]

You people are losers and quitters.

Why?

Because no one on this thread has put forth the option of taping 11,100 magazines together so as to shoot 33,300 rounds per second.

C'mon people, let's step up our game.
