I recently used a dremel stone to remove burr from locking wedge sleeve on my R9. Now I want to polish it, but can’t find a tool that is good fit for sleeve diameter. Has anyone found something that works?

You're scaring me... ???
Now I want to polish it, but can’t find a tool that is good fit for sleeve diameter. Has anyone found something that works?
How about a strip of some 1200 wet-n-dry wound around a small dowel, so it fits/spins loosely in the wedge pin hole?

If the wedge base is cylindrical like a Crosman you may be able to use bore paste on the wedge base and spin it polishing both surfaces at once.

You will have to mic your wedge and find a wood dowel, round stock delrin or maybe even a drill bit shank. Then tape a piece of fine paper on it and have at it. Luckily none of the ones I have done needed it. I do polish the detent on the o.d. and both faces. Also polish both spring ends. I like to use extreme weapons grease (EWG) on the spring and detent wedge. I also use this on sliding comp tubes, pivots, trigger components, detents, etc. I personally stay away from moly in this area but others use it.

This wedge has been a challenge. I degreased and applied krytox to the new gun about 20 mos ago. I've been back in twice since then, when the latch up started getting increasingly stiff, requiring xtra force to close the barrel. The first time I cleaned the wedge of a fine black dust (like fine dry charcoal dust), deburred the sleeve, and re-krytoxed the assemble. Worked fine for a while. Then became stiff again. Today, I opened it again, and again found some dry black dust. There appeared to be a dried film on the wall of the back half of the sleeve. I used a small diameter bronze bottle brush, which seemed to work pretty well, then re-greased and reinstalled. Once again, gun is cocking and locking smooth as can be. I hope that is the end of it. If not, next time, I may try to remove the krytox and return to traditional grease. Thanks to all who offered comments.

IMO moly paste is the best lubricant for the the chisel detent. I use Krytox for a lot of thing. Never on chisel detent or pivot bolts.
Also make sure you inspect the detent around the pin notch. Some times the pin will catch the edge of chisel during installation and deform the chisel, giving it a high spot to snag to bore. Also be careful not to oversize the bore trying to make it super smooth. A polished oversized bore is worse than a smooth enough correct sized bore.

I agree. My latest addition is an HW35E. Out of the box, the breech lock wedge was dragging a bit and felt very rough. I was a little worried it was going to hang up and damage the tip of the stock. Instead of immediately removing the barrel and smoothing up the breech lock wedge and channel, I applied moly grease to the channel, lock wedge and cross-piece.
After my initial test-shooting session and some pellet testing, the action of the breech lock had smoothed out considerably. I cleaned off the excess grease, added a little ceramic lube, and it's fine now. The HW35 has a much different breech lock system than your R9 but, in my case, the high-moly-content grease smoothed out a parts fit that I thought would need hand work to fix.
