Like the title says. I need it for an optics mount, so it needs to be solid, but it's for a knock-off Aimpoint that won't be on the rifle most of the time, so I'm not really looking for something expensive. I'd like to find someplace local, but I'll mail order it if I have to. Can you please point me in the right direction with brand/model and maybe a store to look for it? Something with a quick release would be ideal.
