I have had mine for 12 years (Colt), I keep it reasonably clean, not a fanatic, no rust yet.
Uh...There have been quite a few topics pertaining to the finish of the Ar-15/M-16 lately (also mags). Try looking for some past topics or use the search feature. Alex Also
Not unless you have a shoddy finish
are they easy to get(pick up)rusted?
No, they range from purple to black and any friggin' color you want. Not joking, You can have purple with pink pokadots if want.Heh, only if you really want it though. Alex
are all AR'S finish the same?
