$45 for a hollow piece of aluminum and no screws? don't buy the 10mm without a plan for attaching - Reptilia ROF Riser for Trijicon RMR

Really?? $45 for a few dollars worth of aluminum and you can't be bothered to provide screws long enough to use it? The 10mm if what I needed, but optics never come with screws long enough to mount on something that thick, so maybe providing a few screws might have been a nice touch...
