NUPROL BOCCA KEYMOD 4″ RAIL

I have a Nuprol BOCCA Keymod 4 inch rail for sale in black. In the box there are the screws for the rail and some shims. Only mark on the rail is a hole I drilled in it to try and get it to fit to a receiver I was trying it on. Hole doesn’t affect the functionality and is on the bottom so not that visible when in use. See pictures. PayPal and postage charges not included but can provide a price upon enquiry Thanks for looking, Dave
