Bullets are not going through objects without collisions?

I'm working on a gun right now which fires out bullets. I want them to go through objects that have collision turned off (borders, hidden parts, etc.), but they stop when they reach the object. Also hit.Name can't seem to detect the bullet. It'll return the name for any object that touches the parent of a script that has it but it can't detect the bullet.

Here's the server script. I got most of it off of a tutorial here: https://devforum.roblox.com/uploads/short-url/WQW6iS1i344HHrPXbvyIA1pUWV.rbxl and the page that goes along with it is here: https://devforum.roblox.com/t/how-to-make-ranged-weapons-with-bullet-movement/606618/2

Any help is appreciated :) I'm new to Lua scripting so I would prefer answers that give me the entire working script to copy and paste in.

Once again, the problems are that the bullets don't go through objects with collisions and that other objects cannot detect a hit by them. This is only part of the weapon so it'll help to reference the whole tutorial for the other parts and scripts.

local weapon = script.Parent

local fireRemote = weapon.Fire

local configs = weapon.Configuration

local speed = configs.Speed.Value
local dropDistance = configs.DropDistance.Value
local damage = configs.Damage.Value
local dropAngle = configs.DropAngle.Value

local function CreateFire(startPosition, direction)
	local ray, object, position

	local bullet = Instance.new("Part")
	bullet.Name = "Bullet"
	bullet.FormFactor = Enum.FormFactor.Custom
	bullet.Anchored = true
	bullet.CanCollide = false
	bullet.Massless = true
	bullet.Locked = true
	bullet.Parent = game.Workspace

	local function RayCast()
		ray = Ray.new(bullet.CFrame.p, bullet.CFrame.LookVector * speed)
		object, position = game.Workspace:FindPartOnRayWithIgnoreList(ray, {weapon.Parent}, false, true)

		local dropDamageModifier = (position - startPosition).Magnitude/dropDistance
		local _damage = damage/dropDamageModifier

		if _damage > damage then
			_damage = damage
		end

		if _damage < 1 then
			_damage = 0
			game:GetService("Debris"):AddItem(bullet, 0.01)
			bullet = nil
		end

		if object and bullet then
			local humanoid = object.Parent:FindFirstChildWhichIsA("Humanoid")
			if humanoid then
					humanoid:TakeDamage(_damage)
			end
			game:GetService("Debris"):AddItem(bullet, 0.01)
			bullet = nil
		end
	end

	bullet.Color = Color3.fromRGB(255, 150, 0)
	bullet.Material = Enum.Material.Neon
	bullet.Transparency = 0

	bullet.Size = Vector3.new(0.2, 0.2, 2)

	bullet.CFrame = CFrame.new(startPosition, startPosition + direction) * CFrame.new(0, 0, 1.4)
	RayCast()

	local createBulletTrajectory = coroutine.wrap(function()
		while bullet do
			bullet.CFrame = bullet.CFrame * CFrame.new(0, 0, -speed) * CFrame.Angles(-dropAngle, 0, 0)

			RayCast()

			wait()
		end
	end)
	createBulletTrajectory()
end


fireRemote.OnServerEvent:Connect(function(player, mousePos, startPos)
	local direction = (mousePos - startPos).Unit

	CreateFire(startPos, direction)
end)
