I have lots of 3 lug mounts from proabably nearly a dozen different mfg. More or less they all have easy or semi easy access to the spring in the system and indicate you should lube it. So I clean and lub those springs that pretty often. But more or less they are all hanging out there.
I needed a hub 3 lug and the recomendation was the RS Titanium Tri-lug. It has a relatively sealed (or seems so) spring so do you take it apart periodically? Soak it? what? for those that have this. No help on their website or the interwebs that I can see.

Edited to add looking more closely at the design and available space I'm guessing they use an oring or an elastic buffer as the spring rather than a metal spring as you see in my other mounts.

RS meaning Resilient? If so, I have their Gen 2 tri lug since July. It is semi-sealed, but I did run into a problem where it was essentially letting the can flop around recently. I pulled it apart and cleaned it, lubed it, and reassembled. It don’t solve the problem. It felt like the spring was done, because it wasn’t pushing the can forward. I emailed Resilient and they said the O ring may be over-lubed and causing it to stick, but they said they’d look at it for me and asked for my shipping address (I assume to create a shipping label). I had things come up, and a few days went by before I and a chance to mess with it, and wanted to look it over before I replied. The mount is working correctly now and holding the can in place with proper tension. I assume in the interim that enough of the oil migrated around to allow the O ring to start to work correctly and not bind or drag.

I think what happened was I initially didn’t tighten the inner assembly together well enough and it started to walk loose, letting fouling into the spring compartment and the channel where the O ring sits. I believe if I went ahead and pulled it all apart, soaked it in Breakfree until it’s spotless, lube lightly, and reassemble torquing the two parts together, it should be just fine for an extended period of time. But yes, it has an O ring and a spring.

All that said, I’m going to switch everything over to Plan B since my can is rifle rated. Last night, I shot it with the manufacturer and he said I’d hamstrung myself by putting it on a tri lug.

obviously you don't have real subguns as its machined into the barrel on the 'right' stuff...
thanks for the description. I think I'll take it apart before I use it to see what I have...

I recently had the same experience with my Resilient Gen 2 adapter on my CAT MOB. I was swapping it between two guns and it suddenly felt like the spring wasn’t pushing it back when mounted it. Previously, the spring was pretty strong and it took a decent amount of force to lock and unlock it on the lugs. Took it apart, cleaned the piston (sleeve) and spring, and lubed the O-ring. It didn’t seem that dirty to me, but I noticed that the retainer that holds the spring and piston was loose (easily unscrewed by hand). I have a second adapter, still in the package, and it can also easily be unscrewed by hand. What strange is that SiCo recommends tightening their spring retainer to 180 in-lb, and it’s a very similar design.

OK Dwill104 many many thanks for that. I get the design now. And seems easy enough to maintain.
Mine you can't unscrew new in the package by hand but whatever. I don't see any torque spec from RS but 180 doesn't seem excessive and I'll just mark the thing to see if it moves.

Based on your description, we had the exact same experience, including it not seeming all that dirty inside. Apparently it was enough to interfere with how it functioned. Should work great as long as the inner sleeve (or whatever we want to call it) does not start to walk loose.

Took my brand new one apart and there was not a bit of lubricant in there. So plan to address that.
This is well designed in terms of having good options to torque and remove it so i’m going to run a bit of low strength thread locker to
address the come loose issue.
