I've been lurking here for quite some time and have learned a ton. You guys ROCK! Now I need some specific help. I have a Left Handed Remington 700 that I am going to mount a Vortex Viper PST 6-24x50 on. I want to go with a one-piece picatinny base, either Nightforce or Seekins. I also plan to mount an angle indicator to the base. I have never personally seen either brand's base and am wondering if they are ambidextrous or if there are any other pluses or minuses that I should be aware of?
