Terry , I'm not a big fan of any one piece mount with rings built in, even DNZ on this type of rifle. Smaller calibers it's fine we are talking DG's here. Where I run into the biggest problems is switching scopes and keeping rings as wide apart as possible and as low as possible. If you were to use this type of mount on a DG rifle and expect to use irons sights in a pinch Fairly Quickly, it's not happening. Since most people are probably not going to take two DG rifles over, it only makes sense to either have two scopes set up for the rifle, or one DG rifle with irons, and DG rifles should have irons anyway as a backup. Rifles get banged around pretty hard over there. You slip, you fall, the truck slams it around in the back , I guarantee it's not sitting in a hard case when you are out driving, it will probably be in a rack so you can get to it fast. Hell we drove into holes in the long grass that I thought would tear off the trucks front end, just stopped dead in the water, every thing went flying including the spare tires and ice chests, lucky it didn't slam against the rifles.
Most DG rifle scopes are pretty low powered 1x4, 1.5x5 , 1.75x 6 along those lines. You just don't need anything bigger in magnification on a DG specific rifle. You should take two rifles anyway one for lighter game and a heavy rifle if you are going for the big stuff. My problem is you might see a Buff at 200 yds and wound it and have to go in the thick stuff to get it out. That PH is going to be pissed, Sorry if a person can't hit a toyota truck side window at 200 yds they probably shouldn't be out there.
I do agree a one piece mount is stronger, that's without question, but and I don't care who makes the one piece mount, you still don't have the room of a two piece mount to get to the receiver port especially if you need to fiddle with things on the left side on a right hand rifle. When you are using these boomers if far better off keeping the scope rings as far apart as you can so long as you get the correct eye relief and sight picture in the scope when you snap the rifle up. When you keep the rings apart like this you don't put as much torque on the scope and base screws, and it's mounted stronger. Lower is stronger also due to the torque put on by recoil. Big heavy scopes mounted high with narrow ring spacing is a bad thing on boomers. Granted there are times when you decide on a scope you may not have the perfect set-up at least for strength. I'll change rings and bases in a heartbeat to keep the scope where it should be. One nice thing about lower powered scopes is the objective lense usually doesn't have a bell on the end and give you a much better or longer mounting surface to play with. Some people may think it doesn't look as pretty as a more standard scope, I could care less about pretty as long as it works every time. Smaller lighter scopes less mass in turn means less torque under recoil. Don't be out there with a cheap Bushnell on a DG rifle, buy the best scope you can afford.
Choose your scope and mounts wisely.
