Honestly? Contact WE. I've been in touch with them to get replacement parts for a G18C, they seem quick to respond and very friendly. I'd at least give it a shot. Evike is a bitch for shipping and import fees, even for something small. Cost me an arm and a leg for something as stupid as a sling plate for an M4....
