I'm not seeing what the issue is, the mount looks perfectly fine to me. Are you referring to the little chipping around the edges? That is pretty normal for hard anodizing, which can be fragile at sharp corners as there is very little aluminum substrate to build upon. A fix would be to break all the edges, but this adds cost, especially if it is done manually. I bet the folks at Geissele dd a cost/benefit analysis and concluded that additional cosmetic improvement was not worth the increase in price considering that the needed to be competitive for government sales and the majority of the civilian market. I'm pretty anal OP, I've touched up plently of brand new uppers and lowers (lip around the ejection port) with some Birchwood Casey Aluminum Black. Then I use it, scratch it, and laugh at myself for bothering with it in the first place.
