Would you be interested in a made in Indiana INGO-15 lower? Below is an example of a lower that did not work out several years back. What we are looking at going forward would be far superior with the markings.
I don't generally pay a premium for a certain lower. I've always been one of the "a lower is a lower" guys, buying mostly Anderson stuff.
That said, I'd pay a little extra (within reason) for an INGO lower. But I'm not interested in paying $150 for a mil spec lower with a fancy roll stamp.
