How to make a running math.random script when certain models are in certain areas in the explorer?

Hello! My script im about to showcase right now is for my FPS game where it spawns guns from the ServerStorage automatically, however there has been an issue that i cannot use the script on many maps because if i do then too much guns will spawn at the areas i didnt want the guns to be at, heres the script (the map is in serverstorage FYI and this is a normal script in SSService)

function generaterandom()
--[[    local Ops = game.Lighting.Ops
    local OpChil = Ops:GetChildren()
    local Op1 = Ops.Op1
    local Op2 = Ops.Op2
local Op3 = Ops.Op3 ]]--
--Put variables here.  You can also replace 'local generate = math.random(1,3)' to 'local generate = math.random(1, #OpChil)'.  # means number.


    local generate = math.random(1,4)   
    if generate == 1 then
    --Function
        local Mod = game.ServerStorage.Guns["AUG A1"]     
        local clone = Mod:clone()
        clone.Parent = workspace
        clone:MakeJoints()
    elseif generate == 2 then
    local Mod = game.ServerStorage.Guns["SCAR - L"]   
    local clone = Mod:clone()
    clone.Parent = workspace
    clone:MakeJoints()
    elseif generate == 3 then
    local Mod = game.ServerStorage.Guns["Honey Badger"]
    local clone = Mod:clone()
    clone.Parent = workspace
    clone:MakeJoints()
    else
    local Mod = game.ServerStorage.Guns.MP5K   
    local clone = Mod:clone()
    clone.Parent = workspace
    clone:MakeJoints()
    end
end

generaterandom()

What im trying to figure out is how to configure the script to work on only 1 map instead of all maps since it auto matically spawns when you run the game, (in other words if i put this script for map1 and not map2, im trying to figure out how to make it spawn for map1 only without it spawning when map2 loads into the workspace)
