It's a decent buffer tube but.... - JE Machine Tech AR-15/M4 Adjustable 8 Position Fluted Buffer Tube

Decent buffer tube, has a really cool design, and didn't have any issues but one.... Unfortunately it's as deal breaker, I don't like being swindled. When you advertise a buffer tube made from 7075 aluminum but I receive 6061 aluminum, even if the product t good quality, it's not what you told me you were selling!
