The Stag 2HT looks nice.
I have built my share of ARs over the years, both for myself and customers. I keep ending up back at Stag. In my opinion their pricing and their quaility is top notch. I have yet to have a Stag lower, upper, or complete rifle fail me in anyway related to the manufacture. Their customer service is top notch too. I called them up recently because I had misplaced my fire control pins and they sent me a new set at no charge.
All of the Stag uppers and barrels that I have used have all shot 1/2 MOA and have never needed a "break in" period. The only down side is that all of their barrels are twisted with a 1/9. Which really isn't that big of a deal unless you're planning on sending heavy rounds long distances.
I like all the looks of the AR front ends. I built my latest CQB rifle without a free float but I've built my share of free floated uppers in the past.
I do like these 2 from BCM just not sure which I want to get. Both same setup minus one is a BFH (1/7 twist) barrel and the other is a 410 stainless. Not sure which would be the better coice.
