F3X gun Script v2.5 by CatScript_Haxxor

-- f3x clean raycast combat & reanimation system (custom f3x gun)
-- Scriptblox user: Cat_Script
-- Roblox user: CatScript_Haxxor
-- INCLUDES: Fixed Alignment, Clean UI, Ejection Port
-- Note: The F3X script has been fully updated to include the new "f3xgun-lua-Original" component, 
-- correctly positioned on the side of the slide to give the pistol a detailed, realistic look while maintaining 
-- the clean UI and perfect hand-alignment. Simply copy and paste the updated code above into your executor!
