I've posted recently about wanting to build my first AR and have asked the same question as countless others about what brands should I look for. With a ton of companies making parts out there, I'll flip the question and ask "What companies should I/we (for the other noobs) stay away from?"
I cant really help on the ones to stay away from but the top two that i like is stag and rock river. I used to own a rock river and never had a problem out of it. I now own a stag full mil-spec 5.56 M4 and would not part with it.
