I'm trying to mount a Magpul RVG(or MVG, the one that works with rails) to a cheap Quad rail grip for my paintball marker(I don't think this is Magpuls fault; the rail was made undersized) The rail is to narrow for the grip to clam onto. Does anyone know of any kind of shims or adapters for rails? It jiggles quite a bit, but I really want to use this grip on it.
