I purchased my 1st AR from stag through ACME ARMORMENT 2T model Oct 2008-------flawless and gobbles even the cheapest of steel case ammo.
I also purchased a T2 upper on a group by in 2009----took 6 months to show up but saved about 150.00 came with stock and LPK to boot.
When I was trying to decide through phone calls and emails and forums STAG by far beat the snott out of everyone for customer service.......They even called me back when they said they would and answered every email. At the peak of the AR rush it was takeingthem about a week to answer my emails. I have yet got email response from BM,DPMS,S&W, . Also what I liked is when I called STAG directly I never got the Ahhmm,MMMM, yeah i dunno, let me transfer you ring ring ring ring.........................LMT and larue where very good on Customer support but a decided on a budget of 1000.00 or less for a bare bones AR
