Cloned part gets deleted a few seconds later, how do I make it stay? [SOLVED BY ME]

Here is my code so far (This is some part of it that is cloning the model, but is actually 164 lines of code):

-- Since the chances are hit, we will make the gun.
					
					-- We want the gun in an random location, so we choose a varible for that.
					local offX = part.Position.X + math.random(part.Size.X/4, (part.Size.X/4)  + 5.5)
					local offY = part.Position.Z + math.random(part.Size.Z/4, (part.Size.Z/4) + 5.5)
					
					-- We set a primary part for the model.
					local primaryPart = Instance.new("Part")
					primaryPart.Parent = workspace.A
					primaryPart.Position = Vector3.new(offX, 2.5, offY)
					primaryPart.CanCollide = false
					primaryPart.CastShadow = false
					primaryPart.Transparency = 1
					
					-- We clone a certain model.
					local guns = workspace.__GUNS__:GetChildren()
					local gunSelected = math.random(1, #guns)
					local model = guns[gunSelected]:Clone()
					
					model.Parent = workspace.A
					model.PrimaryPart = primaryPart
					model:SetPrimaryPartCFrame(CFrame.new(primaryPart.Position))
