I have a 6x with a 30mm tube. Glass is very good. It is very heavy for a fixed six, but I have it on a short barreled 54 cal muzzleloader and I really like the extra weight. With the recoil of the rifle, I have never had any problems with the scope but I don’t shoot my muzzleloader all that often outside of hunting season.
If you can live with the steel tube weight they are a good buy.
