I just got my 15-22 a few weeks ago. shot it once, cleaned it shot it last weekend to sight in a new scope. I noticed that the rem oil looks as if it has eating away at the plastic piece that holds the action and blue spring. it was eating away the the corners where excessive oil built up.
Just a PSA for other owners not to use Rem oil. i read on another forum someone used rem oil on a different gun, said it softened the polymer enough for the spring to stick into it. or his finger nail. i think i might get the polymer safe cleaner and the oil it with some car oil or light grease

Does it have any warnings on the bottle/can that cautions aginst the use on plastic parts?

no warnings at all.
oh also dont buy 3m command, i purchased over the weekend and now i have 2 nice Hayden Lambson pictures that need new frames and glass for.

This isn't the first time I have heard of Remoil being hard on some poly.

It even comes in a poly bottle!

I've been using RemOil for years and never noticed the condition the OP mentions. Then again, I don't give my firearms a bath in the stuff or run them wet.

I put a few drops on the bolt before I shoot, have since new and nothing wrong with mine in thousands of rounds, and i don't always clean it right away either.

Sounds like a good reason to own all steel guns! Seriously I have used Rem Oil on my guns for years and never saw any reason to change. Includes some collectables. I saw a post last year about it having water in it. You have to wonder about who started that one because oil and water dont seem to mix well.

There's all sorts of nonsense posted on the Internet with no factual basis.

FWIW, I see no need for more than a drop of any lubricant on the trigger and hammer pins. Any more is simply a waste. Same deal with the bolt carrier. Most folks new to firearms overlube them, no matter what kind of firearm it is. Additionally, a firing pin/striker should never have any WET lube on it; DRY graphite or similar is all that is necessary.

not a fan of rem oil or any other remington product excluding there firearms which i do really like. I personally use hoppes gun lube and/or breakfree CLP. seems to yield better results for me.

There is nothing in the 15-22 that requires a heavy oil, such as auto oil or grease. Greasing up the bolt and or bolt carrier is just asking for gunk to accumulate in the grease and cause malfunctions. Even the trigger/hammer engagement surfaces need just a trace of a THIN, moly-based lube.

I have been using RemOil for more than a year on my 15-22 with no problems of it eating into the polymer stock. I even used RemOil to help remove the extra tacticrayola when I did my gun with no problems.

And even worse I use slide gun grease on the slide rails of my 15-22 and the slide of my Sig 229R 9mm without any gunk collecting. I prefer the ablity of grease to stay where you put it on the slide and IMHO is gives better wear protection on the slide areas of the firearm. I can see where in the " Sandbox " grease would attact and hold grit and gunk but I give my firearm regular cleaning so no gunk accumulates and I am not in the " Sandbox ". But hey that is just me and everybody has a different opinion which is no less valid.

Rem Oil is a mineral oil

Automotive oil is a mineral oil

Automotive grease is a thick mineral oil

If you're afraid of mineral oil, I'd suggest you try silicone.

I use bacon grease myself, but it's not for everybody.

heck i use non chlorinated brake cleaner to clean everything, except wood and painted items, then rem oil for years. no issues and most my guns are polymer, save for the safe queens, who still get remoil. i think something else is going on with the OP's gun, it sure isn't the oil, being mineral oil. also i use straight brown tub axle grease. a dab on the rails is all it needs and a tub will last forever! lotta guys use mobile one, a quart of that would last a lifetime also.

I have some in a aerosole can, I generally just use it on a rag to wide barrels down with before going back in the cabinet. Mostly I guess I use Outers products.

I use RemOil (sparingly) on all my firearms, both steel and polymer. So far to this date, I have never noticed any bad reactions or damage using it. I don't think I have ever even heard (until now) of mineral oil damaging any kind of polymer.....

Until I have proof positive otherwise, I will continue to use it. Because it works for me!
