Mine will be here Thursday. I place my support hand grip thumb over my DBAL so it's gonna be nice to get the sight picture higher.
The only thing that concerns me is getting use to the new cheek weld.
I'm so used to engaging specific reference points on my face with the stock for a repeatable lower 1/3 sight picture, ie. my right canine tooth gum line and the rear of the right mandible.
With this skyscraper mount, it will probably end up meeting only the mandible reference point for more of a "jaw line weld" than a "cheek". This would be nothing new as you basically do this for NODS use anyway with a "chin weld" but it's gonna take some getting used too for daylight ops.
