That looks worse then most of the NEA finish bbls ive seen in the past, but as nea said they are not worried about the finish, just how it works.
And on that note, unless the nitride is done incorrect or the item is dirty when it go,s to be treated( bunch of small black spots will show) how it looks will not effect how it works.
There are only a few forms of nitride/nitrate. Plasma, salt bath, gas and controlled gas nitride.
All but the last are not a very good idea for bbls, as they can not get the consistency needed to line a bore.
Most do not use Controled gas notride as it cost WAY to much!!
Also to remember that Plasma and Gas nitride are "treatments" not finishes.
So its normal to see spotty finished.
Salt bath nitride, aka Milonite,Tefiner etc.. used on some Noviskie, S&W and a few others, also Glock looks really nice, but is very hard ( sell almost never consistent) but looks really good.
But still more Consistent then CL bores.
If you are worried how you nea bbls is going to work, I would not, if you don't like how it looks.... well that's up to you.
