Very nice. My plan is to slowly switch over to MARS lowers. I too really like the stippled KAC panels...cheap, very effective, and great looking. My only complaint about my railed MWS is the large profile of the rail in the hand verses these new school slim rails.
In regards to the G10 covers, they're made by RailScales. After looking at these and others for a week or two, nothing seems to compare to these in form, function, and fit based on the reviews. The price is the only thing that sucks it seems.

They make them in a cheaper polymer version as well....

Lastly, and if you hit the lotto....these are designed with a vfg or handstop in mind. So sleek! The cutout is for their own handstop or VFG.
