Meh very first weapon made from scratch.

23: bad argument #1 to '?' (Vector3 expected, got table)

tool=script.Parent
local user

tool.Equipped:connect(function(mouse)
user=tool.Parent
mouse.Button1Down:connect(function()
local ray = Ray.new(tool.Barrel.CFrame.p, (mouse.Hit.p-tool.Barrel.CFrame.p).unit*300)
local hit, position=game.Workspace:FindPartOnRay(ray,user)

if hit then
if hit.Parent:FindFirstChild("Humanoid") then
hit.Parent.Humanoid:TakeDamage(30)
end
local RayPart = Instance.new("Part",User)
RayPart.Name = "RayPart"
RayPart.BrickColor = BrickColor.new("Bright red")
RayPart.Transparency = 0.5
RayPart.Anchored = true
RayPart.CanCollide = false
RayPart.TopSurface = Enum.SurfaceType.Smooth
RayPart.BottomSurface = Enum.SurfaceType.Smooth
RayPart.formFactor = Enum.FormFactor.Custom
local Distance = (CFrame-tool.Handle.CFrame.p).magnitude --PROBLEM
RayPart.Size = Vector3.new(0.2,0.2,Distance)
RayPart.CFrame = CFrame.new(Position,tool.Handle.CFrame.p) * CFrame.new(0,0,-Distance/2)
game.Debris:AddItem(RayPart,0.1)
end
end)
end)

And this weld script works kinda. Explodes then welds.

tool=script.Parent

function pie()
for i,v in pairs(tool:GetChildren()) do
if v:IsA("BasePart") then
local w = Instance.new("Weld")
w.Parent = tool.Handle
w.Part0 = tool.Handle
w.Part1 = v
w.C0 = v.CFrame:inverse()
w.C1 = v.CFrame:inverse()
end
for i,v in pairs(tool:GetChildren()) do
if (v.className=="Part" or v.className=="WedgePart" or v.className=="CornerWedgePart") then
v.Anchored=false
end end end end

tool.Equipped:connect(pie)
tool.Unequipped:connect(pie)

I don't see any CFrame variable.. but I think you meant to do this:

local Distance = (position-tool.Handle.CFrame.p).magnitude

Before welding the parts (which would be before equipping them) MAKE SURE they are anchored.
