The DNZ four screw one piece mount has a lot of surface area and is very light, liking it on a 6.5x284 March rigGet something good that you trust. This isn't the area to skimp to try and save an OZ or two. A solid scope connection is critical.
1 less round of ammo, or many other small things can save you the weight you might keep to get a more robust scope mount option.
I have become a fan of the Seekins and DNZ mounts as of late.
