NC Star
I have a NCStar 6-24X50 on a Mossberg 4X4 in 300 Win Mag. About 300 rounds later it is still fine. Very clear, holds zero. No complaints. I'm ordering another model for my 22. It seems either you get a great one or crap. Apparently, however, their service is out of this world, and they'll repair or replace anything with a problem.
