This is my second D4RGB with stronger, positive detents. I'd like to see this model with 3/8th inch dovetail mount for .22 rifles and not have to buy the 3/8 to Weaver adaptor that makes the D4RGB sit very high on the receiver.
Pros: Easy to use, multiple features.
Cons: Two different size hex tools required.
