If possible one that looks like this (does not have to be stripped). I want to see the FCG pocket side walls clearly for even-ness
Looks good in those pics.
Pictures were taken biased toward the thick side of the receiver. A pics centered on the magwell may reveal more. After checking magwell wall thickness on both sides, look at the outside roll on the thin looking side. It may be the magwell was done correctly but the outside blending is uneven from one side to the next. The magwell itself seems to be cut well. Keep us informed.
OCD has never been known to accomplish much, but being a DD, it's understandable.
Having milled a bunch of lowers from raw forgings (https://www.mdshooters.com/showthread.php?t=4197)If the lower is a little warped, you can be perfectly centered at the top and off at the bottom, just as the OP pictures show.
Have you shot it? Cheap calipers are $5 at the Harbor Freight in Fredneck.
