    Ordered this on 11/20 with a ape lpk and only received the lpk. When the envelope arrived I thought it was off that it was small so I took a video of me opening it to verify what I got since a buffer tube would not fit. I messaged the customer service and IG account multiple times but have not received an update or refund. I have ordered before with no hickups but this is very odd and I just want to be refunded if anything but I need someone to respond first.
