Bushnell is coming out with a DMR 2 that should be out in mid September. It is not 4.5-30 but 3.5-21, I have its predecessor and is a great optic. They have made the turrets lower, 10 mil turrets, illum (if you want that for some reason), and an easier to set zero stop.
They are also improving the ERS and XRS but details are not out yet. Might be worth waiting.
Where did you hear this?
I've been suspecting this would happen ... For such a popular optic not many people have stock and there have been some sales on Bushnell products.
