Nope, plain black like the rest of them. Just got in some K16's with black stainless barrels. I have an email in with OLY to double check. I could have swore that the plinkers came with regular barrels but was checking one from the last batch and it had a stainless barrel. So many AR's sold in the last year I might be mistaken.That wouldn't surprise me. I know several mfrs offer stainless barrels as an upgrade/option to many of their models. Were the Oly stainless barrels silver or finished somehow?
