local Tool = script.Parent
wut = Tool.Parent

function onEquipped(mouse2)
    mouse2.KeyDown:connect(onkeyDown)
    mouse = mouse2
end
function onkeyDown(key) 
    if key == "z" then
    if not a then 
        Tool.Recoil.Value = 5
        Tool.Aim.Value = 0.1
        Tool.ZoomedIn.Value = true
        Tool.Parent.Humanoid.WalkSpeed = 7
        a=true
        Tool.GripPos = Vector3.new(0, 0.1, 0)
    wait(0.07)
        Tool.GripPos = Vector3.new(0.2,-0.,0)
    wait(0.07)
        Tool.GripPos = Vector3.new(0.4,-0.14,0)
    wait(0.07)
        Tool.GripPos = Vector3.new(0.6,-0.36,0)
    else
        Tool.ZoomedIn.Value = false
        Tool.Recoil.Value = 7.5
        Tool.Aim.Value = 25
        Tool.Parent.Humanoid.WalkSpeed = 10
        a=false
        Tool.GripPos = Vector3.new(0.6,-0.36,0)
    wait(0.07)
        Tool.GripPos = Vector3.new(0.4,-0.14,0)
    wait(0.07)
        Tool.GripPos = Vector3.new(0.2,-0.,0)
    wait(0.07)
        Tool.GripPos = Vector3.new(0, 0.1, 0)
    end
end 
end




script.Parent.Equipped:connect(onEquipped)
