sticky synthetic gunstocks...repair ideas?

This much better than acetone.
Used it to remove the gooey stuff off the car removing decals

Hah! I bought a can of this stuff as well, in case I needed to continue experimenting. I tried the acetone first only because xylene supposedly does not dissolve in water nearly as well, whereas acetone dissolves easily and evaporates very quickly. But the xylene is now in my arsenal. :)

I just saw this thread. I’m going to have to try the cornstarch. I have a Browning shotgun that’s sticky as hell, and I really don’t want to go through the hassle of sending the whole gun in to Browning.

Yep, the cornstarch/talcum idea is by far the fastest and easiest solution. When it got wet I needed to re-apply a bit of powder to some spots; that takes a few seconds.

My stock has panels of checkered rubber in a couple spots for added grip, and of course this makes the powder idea a bit messier and more visible. If it weren't for those areas I would likely have settled on powder as the permanent solution.
 
Well, put some cornstarch on my Browning. Took care of the stickiness and basically dulled the camo finish. It also left checkered areas with a visible, whitish layer of cornstarch. However, I can live with that as long as the gun is usable and no longer sticky and attracting all manner of hangers on and hitchhikers because of it.

Yeah, that's one of the videos I found in my search. I did try gasoline, worked a bit but not as well as pure acetone. Unlike acetone, the smell lingers forever, very irritating.

Update: in my continuing zeal to not leave well enough alone, I went over the more-or-less finished stocks a bit with xylene. I like it! With a bit of elbow grease, it removes not only the stickiness but the entire rubberized coating underneath, which can be just "rolled" off with your fingers after the xylene works on it a bit. This leaves the stocks now right down to bare plastic...looks like ABS? It has a bit of a shine to it, but I am now planning to paint it myself so that's not a concern.

Not something I'd do to a gun I ever expected to sell, as I've never seen a DIY paint job that didn't decrease the value of the gun in question, but it's become a bit of a Quest for me now...:)

Is it one of the Brownings? If it is, this is a known problem - google is your friend. A friend of mine had one, and from what he and I could find there's no cure for it other than a new stock/chassis or the EE

This^^^

The synthetic rubber overmolding is most likely polyurethane. The "harder" portions of the stock will be thermoplastic, then the PU would be over molded. PU is a two part process using a resin and a catalyst (Isocyanate), if the ratio of poly to iso is too high you will get a very gummy feel due to under-curing. I believe that this is what has happened. Other issues that can cause this are too much mold release used in the process, resin and/or iso contaminated with oil.

Regardless, this is related to processing, and there is no fix other than replacement.
