Personally I wouldn't like that. All the rough edges should NOT exist. I do get it is a tiny bit scraped off, where does the scraped stuff go/get into? Nothing on an airgun should show that wear even after years of use , but likely FX will fix it down the road.
I'm not sure why FX doesn't tumble/shake/somehow polish all internal parts. It appears ( and I've onl;y seen what's posted on the Inetrnet so???) from pictures lot's of internal parts are not polished, sure it actually doesn't matter on some parts, say a lever where only the locating pin hole and the far end of the lever touchs something but I am used to see ALL parts nicely finished, everything SMOOTH gives less plasces for goop & grime.
OT my 13 year old AA410 shows no marks on the magazine ( after market RC mag).
