I dropped my sks gas piston, now it doesn't fit!!

if it were me... I would put it in a vice (wrapped halfway in leather or something, and not too tight)... Then I would carefully take my file to it, then sand and polish.

banging on it with a hammer on a hard surface has as much chance to deform the round piston head as the fall did IMHO Removing that small bit of metal will do NOTHING to the function, but deforming the head likely will :)

This part, times 2 :)

Edit: Not a machinist, although I do the work of one, and I didn't even stay at a Holiday Inn last night (for those of you who remember that one lol)

just my 2 cents

what size is it.. you got a caliper? It would be neat if you could swage it with an old bullet sizing die :)

I had the same concern. I laid the piston on a softwood bench top. Seems to have worked.
