I know that a local script means its only for that player that changes happen, it doesn't replicate to the server. So I am trying to create a remote event for it then using that event u fire a function inside a script that does the actual dmg so that it replicates to all players.

But the problem is. I don't know how... Can anyone fix up the script and help me?

local Debris = game:GetService("Debris")

local LaserGun = script.Parent
local Tip = LaserGun.Tip

local Player = game.Players.LocalPlayer
local Character = Player.Character

local GunDamage = 30


LaserGun.Equipped:Connect(function(Mouse)
	Mouse.Button1Down:Connect(function()
		local Laser = Ray.new(Tip.CFrame.p, (Mouse.Hit.p - Tip.CFrame.p).unit * 300)
		local HitPart, HitPosition = game.Workspace:FindPartOnRay(Laser, Character, false, true)
		
		local LaserBeam = Instance.new("Part", game.Workspace)
		LaserBeam.BrickColor = BrickColor.new("Bright green")
		LaserBeam.FormFactor = "Custom"
		LaserBeam.Material = "Neon"
		LaserBeam.Transparency = 0.25
		LaserBeam.Anchored = true
		LaserBeam.CanCollide = false
		
		local LaserDistance = (Tip.CFrame.p - HitPosition).Magnitude
		LaserBeam.Size = Vector3.new(0.3, 0.3, LaserDistance)
		LaserBeam.CFrame = CFrame.new(Tip.CFrame.p, HitPosition) * CFrame.new(0, 0, -LaserDistance/2)
		
		Debris:AddItem(LaserBeam, 0.1)
		
		if HitPart then
			local HitHumanoid = HitPart.Parent:FindFirstChild("Humanoid")
			
			if not HitHumanoid then
				HitHumanoid = HitPart.Parent.Parent:FindFirstChild("Humanoid")
			end
			
			if HitHumanoid then
				HitHumanoid:TakeDamage(GunDamage)
			end
		end
	end)
end)
