Go to the link posted above and cast your vote on one of the weapons, doesn't matter if the one you vote on wins or not. You will get the weapon that gets the most votes in game post launch.
This will probably be the only way to get the weapon and might become rare over time, who knows
You also get an exclusive coconut monkey housing item.
Also be sure to use the same email as is registered on your WildStar account. Deadline is may 5th.
