@bfoosh006 really something here to forward to them. If they really look at this, and just straight-assemble and test fire a few rifles, this will all get figured out quick.

I'll fly in there for a weekend, and troubleshoot the entire .308AR line, if that's what it takes. They need a dedicated .308AR Armorer, pretty bad, to design and function test this stuff, instead of piecemealing it minor-thing-by-minor-thing...
