I got a second hand UBR from ARFCOM. damn thing wiggled so much I assumed it was a fake, but the seller seemed legit and offered to take it back. Said it had always felt that way. After some photos sent to magpul and a short phone conversation, they asked me to send it in. sure enough, a week later a brand new UBR showed up with a sticker pack, and a note saYing they didn't know how that happened and thanks for sending it in. all this right in the middle of the boulder air drop and the LEO mag deal so i'm sure they were slammed. good people.
