Who makes arguably the worst AR/M4 style DI guns and why?

There's plenty of talk about who are among the best manufacturers.

Curious who takes the cake as the worst manufacturer these days, in your opinion, and why.

If they are not being talked about as "among the best manufacturers", then they are most likely crap. I'd stay away from most any manufacturer that doesn't give you at least the standard TDP.

Use the search function and you can find plenty of "Who's who in the shitty AR world".
