The real question is why did your friends want to order from this guy after he screwed you over.Whatever you do, avoid 2vetsarms. They make one, and it's about the worst company I've ever dealt with.
Paid the money for the upper and NiBo BCG...got upper and Black Phosphate BCG in. Took me almost 4 months to get my money back because the owner was always "too busy" to get back with me. Had no problems answering my friends who would message him wanting to order though.
