Usual dilemmas about future tech - will it be big, is it better to wait for bigger market / higher price. And do you want cash now? And will a big player want it?
I'd say hold, because a lot of stuff will go modular - that is starting with phones. But here of course it is tricky because firearms are very regulated, and some of what is in them is already modular if you can replace barrels, scopes etc.
