I've reached Gun Nut 4 and Science 3 and all the required components for some upgrades but I still get the "you lack the requirements ..." when I try to upgrade (the upgrade is still not highlighted). Anyone else having this issue or am I not getting something right? Thanks. P.S. this is for sighting upgrade on assault rifle.

What platform are you playing on?

Edit: Which scope? Also, if you look at the needed materials sometimes there is not enough space to display them all. If that is the case there are a few downward arrows. If you see that scroll down to see the other things needed. Perhaps something is there that you didn't know about.

Check out the material list and make sure you have all needed components..? It might be some simple silly thing like that. If you have all level reqs. I cant say for sure, I am not able to play at this moment so cant look anything up.

Edit- never mind see you say you have all that.... Maybe its just some funny bug. Try saving game then shut down and restart and see if you can build

PS4, short recon scope,...I'll check the scroll down thing...wouldn't be the first time I screwed that up! Thanks.

No problem. Let me know if it works out for you.

are you using right joystick to scroll down and see the full requirement list?

Also make sure you have plenty of materials for the item, my game bugs as I've got some quest items that list components, so the crafting shows me having the materials but I can't get them as it's a quest item -.-

Not noticing the little scroll thing was my problem....add that to my long list of gaming shortcomings, but I'll be 68 next week and lots of little things are elusive these days! Thanks for the help.

No problem. Keep on enjoying Fallout 4
