I recently got a Specna Arms SA-C06 for Christmas and I’m wanting to put some attachments on it like a foregrip and so on, yet I need to get a rail to attach onto the handgaurd. I’ve done some research and I think it’s a URX 3 handgaurd, but nothing seems to be in stock or is very expensive. Do you know any cheap ish rails that go onto the SA-C06
