I’ve being working on the guns and the attachments but I have no clue of how to make a gui that you can select the attachment on the gun module with the stats.
I’ve looked everywhere but I cant find anything
So please help thankyou. 
well, that’s kind of a loaded question. there are alot of different things that an attachment gui could mean, and alot of different ways to go about it.
for the gui side of things, you could create a button on the player’s screen that enables a larger gui of all the selections, or use a key to do something similar.
as for the attachments themselves, you could simply save copies of the attachments somewhere in your game, and clone them to a weapon that is trying to equip them, welding them on as they are cloned.
like i said, there are lot of ways to approach it. those are just the first ways i thought of doing them. a more specific description of what you hope to do would be helpful in giving specific help
