The product and pricing is ok, but customer service is awful. I purchased a 10.5" AR Pistol chambered in 300 blackout. I got a 5.56 magazine with it. I sent a message to customer service, this is what I got in return: ================================== Hello Michael, Our 300 blackout firearms come standard with a Magpul 5.56 magazine. This is the correct magazine for your firearm. Thank you for choosing Palmetto State Armory! Best Regards, Andria Palmetto State Armory Customer Service ========================== How can they think that the correct magazine for the firearm is a magazine that hold a different cartridge or "bullet" than what the firearm fires?
