Mesa tactical stock adapter

[CrustyRusty]

I saw that Mesa makes an adapter that allows 12 ga stocks to be used on the 20 ga receiver.  Has anyone used one and if so, do you think this would allow a Burris speed bead mount to be used on the 20ga?

 I just put mine together today,  mesa tactical urbino pistol grip with lucy adapter. Feels solid, I'll put some rounds through it soon. 870 20 gauge

I looked at those adapter on a gun it just to didn't look right. I hate it I wanted to get a camo shutshot stock.
