I bought some pre-ban AR-15 GI contract magazines that were advertised as "brand new." I received them today and unfortunately they don't look very brand new to me. The bodies and internals have no damage and are clean, but the finish on all of them shows some scratches and light spots. This is the case even on the ones that are still sealed in plastic bags. Is this typical for old stock magazines or should I be looking for a refund?
