If you wish to place an attachment in the "luxe" slot or vice versa just change the name and it should be good.

So usually when people release a weapon mod with attachments those attachments only look good with the specific weapon they configured it for, with this mod say no more. The attachments universally work with every vanilla weapon they are compatible with and weapon mod if you configure the weapon nodes to do so.

Features:
Works with every vanilla weapon that supports the specific attachment
Properly configured materials for scopes
