Buyer be ware DDT has changed and not for the good get email saying 30 days to purchase 80% lowers before they have to be serial numbered. I ordered then get email they need FFL to ship I call the guy says we ran out of non numbers automatically switch I canceled the order then get email they returned my money to account I looked and it’s $21.65 short customer service gives me a BS $4 ea to restock something they did have in the first place. Then before I answer that email I get another saying that all I’m getting back it’s my fault picked the sku# with ( s )in it. How does a customer know what your sku# means I’ll never spend another dollar at DDT they pulled a bate and switch customer service sucks and rude. Look into AR industry Attached photo that inspired purchase of a product they never at the time the email came out took them 10 days to send me email they need FFl before I knew there was a problem.
