For how small and heavy MAC's are for their size, as well as the blistering fire rate, they are pretty inaccurate for their lack of controllability. I'm not sure about reliability though.

I feel like it's worth mentioning though that not all submachine guns work the same way.

The MAC does share a lot of similarities with the Uzi. Compact, box-tube, open-bolt submachine gun, made from stamped sheet metal. MACs are significantly simpler and cheaper though, which, again, if we're talking about legally obtaining them, isn't saying much.

I upvote this for the sole reason that Gachi memes are funny.

That's not a Tec-9. That's some variation of MAC. Though, if we're being honest, that thing is probably an airsoft gun, considering it's incredibly difficult and expensive to get a real one legally.
