This will be interesting to watch if/when Magpul does leave Colorado completely. If they open another manufacturing location, but keep what they already have also, I would view it as more of an empty threat. The best for the political reasons I feel would be fore them to leave Colorado completely.
The only questions I would have is:
1. How long will it take them to move and set back up again, including the ancillary support companies?
2. How big of a hit will it put in to their ability to keep current venders supplied at current levels while they are moving?
