Heard the same thing many times years ago, but their QC has gotten MUCH better in the past 2 years. Every one of their guns I own has worked flawlessly from day one.
Well that's good to hear. Their prices are really good if you get a working rifle. Sounds like they've got things figured out now.
I'm not much into AR's(as you can probably tell from my user name). My go-to rifle is a Geissele Super Duty but I much prefer shooting my AK's.
