I had a Mako AR 15 stock adapter for a Mossberg 500, it was okay but the angles were extreme to use with a red dot scope. I just bolted on a Mesa Tactical high tube adapter and it is much more comfy for a good cheek weld with a scope. The Mesa Tactical adapter keeps the same angles and alignment of an AR 15 which I am pretty familiar with. I even find myself reaching for the thumb safety with this stock, I think I will make an adapter to activate the safety with your thumb sometime later.
Before with the Mako
After with the Mesa Tactical (and longer barrel and mag tube)
