Why can’t you take them apart? Legally speaking?
I have a Lane Scorpion King. It’s made to take apart for cleaning.
There are few good points of supressor what you can take a part, and there are also few bad things about that.
It will cost more money to make a supressor that can be taken to a part, more machining, and some thimes if you are not cleaning that kind of supressor enough often, it will be permanently closed when the remnant of burning gun powder become stuck in side the supressor.
Also it will need to have special tools to have it open.
And when you do open it several times, if it alloy, the threads will come loose, and the very big pressure inside the supressor might just
blown out of the slit of the joint of the supressor.
And one thing what will be wear out in the end are the supressor baffles, so i would not want to pay +1000$ for supressor, what is not lasting forever.
For sure there are amazing supressor with big price tag, but not all of us can worth of money to buy them.
Some supressors wear out faster than other, it depend the material on the baffles and the main tube material, and how many shots you shoot thru of it and how quick you do it.
Alloy is the one what run out fastest, but it is cheapest.
On a hunting purpose, that might last decades, but in the range shooting, it might be shoot out in one year.
Ultrasonic cleaner is good way to clean supressor what is welded, and can not been taking apart, but if it is alloy, be aware that anodizing, too
strong liquid will ruin the surface, and too mild wont do nothing.
