Can gun stocks still rise?

The news this am reported gun sales going through the roof after Obama's threat to use the power of the WH to suppress the second amendment.

Here's a link confirming that news.

While gun sales have been going up since 2008, I foresee it accelerating to beat whatever executive order will be crafted.  You know it will happen as this president has bypassed all established processes to damage America.  So, one would hope that whatever order is issued will not be retroactive and the guns acquired before then will be grandfathered. 

Here is an article of the gun stocks and how much they've shot up since 08. Ruger was +700%  !
