Odin works upper - ODIN Works Billet Upper Receiver

I bought this upper specifically for my light weight sbr build. I can not express how disappointed I was when the upper clashed with my MagPul BAD lever after going thru the assembly. So I removed a second BAD lever from another rifle that was worse. The bolt catches every time. The BAD lever is the single best product for fast functional AR weapon management in situations. To have to remove my BAD lever to use this upper just to delete my forward assist is a total loss. I will be putting this upper on a shelf and continuing to use my M&P sport 2 upper. I cant understand why Odin milled this upper in this manor. Also the coating around the barrel fitment was to built up to get proper fitment.
