Suggest a solvent

[bohoki]

I've had that happen to two scopes. With age (~10 years) the paint became extremely sticky. Since I knew there was aluminum under the paint I used acetone but it still took a couple of applications and elbow grease to get it all. Since you've got a fully plastic stock you may need to try a couple solvents in small areas to test.

yea ive had this happen to me with a rubberized flashlight, diskman, bluetooth mouse, tv remote control

9!% alcohol and paper towels cleaned it all off

i'm glad to know it happens to others i was thinking i was cursed or something

Go easy use those 3m spongy things to rub with.

Might have been rosin based stickum. Comes in a spray can. IT is for sticking cows' tails out of the way when milking them....no kidding. Some guys use it to get a better grip. The alcohol cutting it suggests rosin.

If your M2 isn't 922(R) compliant buy a FFT forend and another USA part to make it so.

And again, are you sure it's some sort of adhesive and not the plastic degrading? If it's all over every inch of the forend, then I'd lean towards plastic degrading for some reason. If the goo is not over the every bit of the surface, then maybe adhesive.

Pix?

could be old residue from duck tape? it's very hard to remove if it's been there a long time

If Goo Gone doesn't work, try Goof Off (I use both to remove paint off firearm parts)

Most rifle stocks are glass reinforced nylon. Acetone might discolor the stock a bit but it will not harm it wiping on and off.

My order of solvents is get the nasty stuff first. Acetone, lacquer thinner, go big or go home. I don’t have time to tickle it. I want the job done now.
Then I go to paint thinner, wd40 crap like that.

The adhesive is only on the outer surface. The inner surface is smooth and not tacky.

I just got home, I have some rubbing alcohol and gasoline. Tomorrow morning, I'll try the rubbing alcohol, and if that does not work, I'll try gas on a small section. If that does not work, I'll go buy some Goo Gone.

Have you tried some real sticky duct tape and used it like a tack cloth? On some surfaces, my go-to for removing adhesive is another adhesive.

Worth a shot, cheap and does no harm. Press and rub the tape down well on the surface, then rip it back up. Repeat as necessary and see if anything comes up.

Do a web search for adhesive removal. You'll get a bunch of suggestions for different adhesives. Problem is that different adhesive formulations require different solvents/removal procedures. What will work depends on the adhesive you have a problem with.

And, there's the possibility Eugene mentioned, of the plasticizers migrating out of the stock material itself. It's a common problem on boats where plastics are in the sun a lot. If that's the case, it's going to recur. You can minimize the stickiness by dusting with talc (or cornstarch, if you're talc-free/deficient), but it will happen again, if that is the cause.

This morning I went to get my rubbing alcohol, only to find that my teenage daughter used it all. I thought about using duct tape to see if it would work, and I could not find my rolls of tape, which is my fault for not organizing my garage. I used gasoline and it took the tacky ness off the stock, but I could see a hardened residue, so I used my fingernail to scratch off the residue. The residue flaked off like it was a coat of paint. I continued to scrub the stock with gasoline and a Scotch-Brite pad until it was all off. I would have taken photos, but I don't think the adhesive would have shown in a photo.

3M specialty adhesive remover # 38984
Not cheap, but the best I have encountered.
You will need to go to an auto paint store,
I was a tool dealer and a lot of trade-in tool
boxes that had lots of stickers, this was the
best stuff I found.

The adhesive is only on the outer surface. The inner surface is smooth and not tacky.

Inner surface is less exposed to the environment.

Just a suggestion here.
I've used Easy Off oven cleaner to remove some adhesive material and painted lettering from fiberglass/plastic parts.
