I'm an Armtech, first off, I only thought you could get armstech discoveries from barrels (it's all that's listed on torhead.com). After reading here, I'm finding that you can discover new gun recipes as well.

Now I'm wondering, should I be DEing green drops, and quest rewards as well? can you get recipe's from these as well? or only our own craftable items? Has anyone succesfully learned a recipe from a drop, or quest reward RE?
