Deluxe Pioneer Weapon Set upgrade

this is the way it works for me some of them is in research and when you do it appears in development others i got it in mission and the are added to research. also you can buy some blueprints from merchants or in the apex missions when i send a strike team the some times come with new blueprint for weapons hope it help

This question is in reference to Mass Effect: Andromeda btw... 

Thanks for the tip! I know that's how weapon crafting works in general but, the pioneer weapons are not showing up in research/development at all. Or in any mission. I have them in my inventory but can't upgrade them.   Do you have this set equipped? 

I have exactly the same problem

the pioners that you refer are the one in the pre order bonus?
