supposed to read "rail on top". phone posting... 
$325 is for the suppressor. I got the gun for 310.

 This is the one I paid for. A it has mounting screws on top to put a rail. The rails are fairly cheap too. I may add optics later on, but I want iron sights, they are less likely to fail

 You can find either for a little more than $300
