I get an e-mail occasionally from Palmetto State Armory and this latest one shows they're selling lowers for $69.95 each. FFL fees as well if ordering and in need of a transfer.
I thought about getting one or two until I looked closer at the cost of uppers and necessary parts, not right now and not likely for some time.
Still, if anyone needs or wants a lower or several, they're available along with related parts and accessories, at www.palmettostatearmory.com
