As you can see in the video, I didn't have the correct perk to craft the D variant (Armorer Rank 2), but crafted it anyway.

I have confirmed this works with all other crafting as well.

The game seems to craft whatever is highlighted when the craft is confirmed, regardless of whether or not you meet the perk requirements.

This glitch requires you to be able to craft an item above another item you can't craft. You then need to quickly attempt to move down to the lower item while mashing the craft button. This won't work if you have already crafted the upper item.

Alternatively, on the PC version just use the console to give yourself whatever perks or materials you may need.
