Way out of spec - AT3 Tactical AR-15 Mil Spec Buffer Tube

I bought this tube expecting it to be milspec as the name suggests. The 6 position holes were poorly drilled and the tube wasnt concentric. It was thicker on the bottom which was letting the buffer sit higher and slip over the retainer. This could just have been a fluke in the production chain, but milspec is literally the bare minimum so it's pretty disappointing when it falls short.
