i heard one hunter this year saying he sent his rifle off to have it teflon coated. i forget what company he said he used but he said it took about 6 months to get his rifle back. he said he did this a couple years ago and he has not oiled it since he got it back. he just wipes off the excess water and puts it up. according to him the place he sent it also breaks it completely down and teflon coated the entire inside (all parts big and small). i wish i could remember who he said done it.
