Never dull works great on brass.
Never dull works great on brass.
If Henry suggest nevrdull I would use that. It's relatively soft. From my experience polishing brass, those blemishes should be able to take off with a little bit of effort using Nevrdull. I fear abrasive polishes may make the shine look uneven so I would use a softer polish with less or no abraison like nevrdull. a note when rubbing the polish in and off use a fair amount of pressure, it'll bring the shine out a lot better. Learned this on highly shined silver the hardway as just rubbing it wasn't getting the job done and stripping the small amount of tarnish very well but applied pressure and shine came out within seconds.
The brass might have a coating applied on top of it. Sometimes it's like a clear plastic coating or varnish. I'd try polishing on an inconspicuous area before going whole hog on the sides with an abrasive polish.
Do not use ammonia or windex on brass.

Peek is good stuff but is mildly abrasive so I would avoid getting it into any of the moving parts.

I still have most of a tube I bought at Canadian Tire years ago - it doesn’t take much.

I found some pics of brass with a coating on it. These parts are from a 1980 Browning Mountain Rifle. I tried to polish the tarnish out and my most abrasive cream polish wouldn't do anything. On closer inspection, I found that it had a clear coating on it and looked like ass. I sanded it off with a very fine foam sanding block then polished with polish applied to a microfiber rag taped to the same foam block.
That's a nice looking receiver on your rifle. Hopefully it doesn't have a coating on it.
