I've recently started buying ammo and accessories from Palmetto. I need to jump on there and see if I can get an LPK and an extra BCG if they aren't all out of stock. Man I wish I had their store near me. Too bad they are a days drive away. As for FN, awesome. Would love to own one someday. AFAIK, they are the only other "true" mil-spec manufacturer, besides Colt.
The FN plant here is actually producing the Colts under a Colt contract. When they leave-out they have the Colt stamp accompanied by "Manufactured by FN USA in Columbia, SC."
Yeah, having PSA here is the bomb. All the credit goes to them, started by an academia if you can believe it - he is a professor of Economics over at The University of South Carolina - one of the rare truly Conservative academia you will ever meet ... although USC is a largely Conservative University for the most part.
Within two blocks of PSA's brick and mortar storefront we've also got Sportsman's Warehouse which is another incredible outlet. And right down I-26 from there is Dick's Sporting Goods which will hopefully go out of business after what they've done.
Another couple of miles down I-26 we have
Ellett Brothers (MASH HERE), which supplies guns and ammo to the entire country as a middle man. I've actually been in their warehouse before, when I was a kid growing up just down the road from Chapin, and they probably have one of the largest, if not the largest, inventory of guns and ammo in their warehouse in the entire country.
