Another +1 for Seekins. Not that there's anything wrong with Badger or Nightforce, I just prefer the unique design of the Seekins. Mainly the lo-pro torx base mounting screws as opposed to the large nut hanging off the side which is standard on pretty much all others. In the end they all do the job, it's just a personal preference thing.
I used to use 100% Badger Ordnance until Brownells started carrying the TSR series; solid steel CNC for about $60 instead of $160. Been very happy with both.
Seekins and Badger. I put a set of Seekins on my Cooper 57M 22lr and they are perfect for that application because they are so well engineered and their sleek, robust, aesthetic design really compliment this rifle.
