LOVE my new Russian but I have a couple questions.

Got my Russian 91% yesterday. First build was a snap and it works perfectly. There's only two things I'm not sure about.
First is my fill screw. Unless I take the o-ring off, the fill screw it doesn't sit flush. Therefor I cant flush mount the Russian to the nemesis. There's always a little gap on one side making it look crooked. Anyone else have this issue? Anyone try running it without the o-ring? It's a tight fit, it may not leak.
Second question is about the finish. I can't tell if the R91 is anodized, powder coated or painted. I'd like the finish to match my mate nemesis. I do vintage restorations and have all the tools to brush, media blast, sand and polish the finish. I'd just like to hear from anyone who's attempted to give their Russian a facelift before I do something stupid.

I never use the o-ring on the fill screw. A good tightening and no leaks for me.
I brushed mine to match my Gus- not sure what exactly the finish is, but it was easy to get the brushed look with a scotchbrite wheel on the dremel.

No need for the oring on the fill screw.
The finish, I believe is media blasted and should brush or polish up pretty easily.

Exactly what I wanted to hear. Thanks.

I don't have an o-ring on mine. If you put it together that small o-ring goes on the 510 adj screw.
