I will say Palmetto State Armory usually has a decent selection, but I’ve never been to the one in Denver, NC. If you get to Columbia SC or Anderson SC (and maybe Asheville?), Sportsmen’s Warehouse has a pretty broad selection of glass.
This reminds me, especially of Cabelas or Bass Pro, nothing like asking to see a $2K scope, and they knock the hell out of it getting it out of the display case. My OCD cannot tolerate that.
