Reddit mentions of Stainless Steel Tumbling Media Pins - 0.047" Diameter, 0.255" Length (2 lb Pack)

$22 for enough pins to last long after you're dead. The HF tumbler is $60 before coupon. And you need Lemishine. Thats it.

None of those soaks/methods are going to do anything.

For separating the baffles read your manual. “Oculus 22 Disassembly” part 6 (shown below). Rugged suggest using a hex key to gently pry them apart. I have a set of brass punches that I use the same way to gently apply leverage and pop the baffles apart.

Next, go to Harbor Freight and get a single drum (link) or dual drum (link) rock polisher. Use this coupon for 20% off. I have the dual drum and I use one for the oculus baffles and the other for Obsidian 45 baffles at the same time.

Finally get some stainless steel pin media for cheap from amazon. 2 lbs is perfect for the dual drum, I use 1 lb of pins in each drum.

Fill up one drum with 1lb of pins, the separated baffles, and then warm water until it covers the baffles completely. Give it a small squirt of Dawn dish soap and you are set. Seal the lid on the drum and let it tumble for 2-8 hours. The longer you go between cleaning, the longer you can tumble.

The stainless pins are softer than the 17-4 steel baffles, so they won’t hurt them at all.

After that 2-8 hours crack it open. I like to go back by the woods in my back yard and pour it out through a mesh steel strainer. Make sure the strainer has smaller holes than the pins. This should catch all the pins and baffles and let the carbon, water, and pummeled lead through. I hit the strainer contents with a garden hose for a bit to clean it all out.

Go back inside and dry everything off. They should be 80%-90% clean. Any large remaining chunks of lead you can scrape off with a brass punch. I also like to take a spent .223 case and flatten the mouth in a vice. This makes a nice sharp and flat scraper as well. Scrape off any remaining simple to get lead. They should now be 90%-95% clean.

This final scraping is not necessary and only if you really care. You don’t need to get every last chunk off. It will just get dirty again, and a dirty suppressor is a quiet suppressor.

All told, this is the cheapest and easiest way to clean steel rimfire baffles. Ultrasonic is only decent on carbon and doesn’t do much to separate lead from baffles.
