Yeah, I agree, BGfisher. There are several levels of customer service that should have taken care of the problem before it ever got into the consumer's hands. And, real world, assuming I'd taken my flashlight and verified the holes had actually been tapped in the first place, I admit I'd just chase the threads out myself rather than haul the bow back to the shop. But still, I'd be P.O.'d.
I'd definitely send the manufacturer a nastygram.
If the holes hadn't been tapped at all though, that's a different issue. That bow would definitely go back. It wouldn't be the first time a CNC machine had broken a tap and run off a more than a few parts before the operator (aka semi-trained monkey

)caught it. Things like that can easily slippast even the best inspectors.
