Guess I'd recommend doing a search. Otherwise...there seems to be afair amount of guys that have success with EGW...but they (EGW ) have some rings with problems ( According to internet reports). I have had great luck with NightForce, Ken Farrell and Badger Ordnance. None of the ones I've listed that I prefer are necessarily inexpensive. But...With experience, I've learned that you get what you pay for....especially in optics, mounts and rings.
Good Luck,
Wayne
