Any recommendations on serviceable suppressor for .22LR pistol?
If you avoid aluminum baffles, and stick with stainless steel or titanium, wet tumbling with stainless steel pins seems to be the easiest and most effective cleaning method.What about cleaning them?
Would ultrasonic cleaner be a good choice for removing carbon?
You have to be especially careful if you use "the dip", as that can be absorbed through the skin.You end up with some nasty toxic waste that needs to be disposed of because of all the lead.
Threaded 22LR suppressor host pistolsIt sounds like you're also looking for suppressor recommendations, so I thought I'd cover that separately.
My first recommendation is to focus on something with stainless steel or titanium baffles, for ease of cleaning. Aluminum will be less expensive and will save on weight, but you are limited to hand scraping or soda blasting the baffles. With stainless steel or titanium, you have the option to use ultrasonic cleaners, stainless steel pin tumbling, or "the dip".
My personal favorite balance of weight, length, and performance is the AAC Element 2. It has stainless steel baffles and a titanium tube, weighs 4.1 oz, and is 5.25" long. It also has one of the lowest first round pops in the industry! It's an older design, but still a great suppressor. The only drawback is the lack of shielded baffles, which can make disassembly a little more difficult when dirty, but they include a pusher tool to help with removing the baffles.
Sound-wise, my favorite suppressor is the Dead Air Mask. It's a bit heavier, being mostly stainless steel, but it sounds amazing! It weighs 6.6 oz, but is a bit shorter than most competitors at 5.1" long.

I also have a SilencerCo Spectre II that performs well, but it's both long and heavy at 6.8 oz and 6" long.

Another suppressor that gets rave reviews is the Rugged Oculus, which is 4.3 oz and 3.25" in short configuration and 6.9 oz and 5.25" in long configuration.

If weight is a serious concern, you could go with an all titanium option such as the Energetic Armament NYX, which is 3.6 oz and 5.6" long, or the modular NYX Mod2 which is 2.45 oz and 3.7" in short configuration and 4.15 oz and 6.5" in long configuration.

A couple of other options that get good reviews are the Q El Camino (4.3 oz, 5.95") and the TBAC 22 Take Down (5.9 oz, 5.6").

There are plenty of options to choose from and most of them offer similar performance, but I still highly recommend choosing something with stainless steel or titanium baffles. You'll thank me later...
