Cproductsllc.com. I am planning on buying some from there, well, ordering from there this week. Where are you located, close to Bloomington? I'd be interested in a split buy so we could save on shipping, if you are.
I have 3 brand new mags I bought from Bradis last year. I think the price tag is still on them. If interested I'll dig them out and see how much they were.
EDIT, Found them. They are still sealed and say" DPMS 308 Mil Spec 20RD $39.95"
