Please.remember Facebook does not.allow any posts related to gun sales or purchases. This includes anyone willing to purchase guns in a misguided and improperly named " buyback" scheme. It would be terribly unfortunate if an official government or law enforcement agency decided to advertise such a "buyback" on Facebook and was repeatedly.reported by the law-abiding firearms community. My understanding is if you post a price (buying or selling) it is a permanent ban for the account. Let's hold everyone up to the high standard we all expect.
