I purchased a completed AR15.COM billet lower a few months ago and am trying to find out who manufactured it for them. I'm just trying to find as close to a perfect fit billet upper as possible. Any help would be appreciated.
I would ask in the arfcom store section. I'm sure JLA or Avila will help you.
They won't tell me, but maybe they will tell you
Some companies are close lipped about who does their manufacturing for them. I did ask about the forged lowers once and all I was told was it was not the forge I thought it was.
