Greetings,
Testing a gun, I looked at the output, and saw this error message:
-- 14:01:27.682 - ServerScriptService.M4A1.MainScript:35: attempt to index field 'Parent' (a nil value)
How could I solve it?
In general this means that the Parent object cannot be indexed (this can either be because you have prematurely destroyed it before a necessary call, or it just doesn't exist).
Take a look at line 35, see what it says, and seek to make amendments to whatever is being indexed's parent before/on line 35.
