Loved it until i put a level on it - NightForce Remington 700 One-Piece Bases

I had the short-action version. At first glance I loved it! Once the base was fitted to the action, I plumbed the rifle in a vise so that I can zero the scope. Once the rings were mounted, I took the ring caps off and checked zero again. The front ring was true, but the rear ring was not. This didn't make any sense so I took the rings off and placed a digital level on the base. Sure enough, the base was zero in the front, and -2.7 degrees to the left at the back. I took the steel base off, and mounted my nightforce 30mm 1-piece mount back on the rifle and measured it. The one-piece mount was true both front and back on the level. Still out of disbelieve I took the steel base to a machine shop at my work complex. They placed the base upside down so the picatinny was sitting on their machinist block, and low and behold, this steel base rocked back and forth on their machinist block meaning that it was indeed twisted. Here's hoping that my base was just a bad day at the mil, but I suggest that you turn this base upside down and place it on a flat surface to see if it rocks before mounting it.
