I picked up a M&P 22 Compact this afternoon.
I screwed on my Dead Air Mask and shot for a bit.
I went to unscrew the suppressor and the adapter came off also. It is now stuck in my Mask. I tried to use the wrench that came with the M&P to remove it. No luck thus far. The end cap with the stuck adapter is now in my freezer.

Dead Air isn't open until Monday. I just thought I'd see if anyone had any ideas. I don't have a strap wrench small enough to grip the end cap.

Vice on one end? Smaller strap wrench? Either might be easier than sending it in.

Does the adapter have wrench flats on it ?? If yes then just remove the end cap and vice it and use a wrench. If no flats you can still vice it and use channel locks...

Try shooting it (to heat it up), then see if you can remove it.

Also, liquid wrench helped when I had my 22 Sparrow in a similar situation.

Spray it with Kroil, let it soak for 15 minutes and try again. If need be, wrap the other end with a piece of leather and clamp in a vise. Be very careful with that!

I agree with kroil or some other penetrating oil. Heat is going to be more effective than cold, too.

Can you unscrew Mask end plate and take baffles out?
Thread adapter and last baffle in ultrasonic to unscrew.

Try shooting some more and get it hot, or you will need a vise and a strap wrench to get it off. If you don't have a vise try two strap wrenches. Once it's off start using 'Thread Smart' antiseize on all threads on the suppressor as well as on the adapter and threads of your barrel, and even inside the tube.

Griffen Armaments recommended it; you can buy it online at McMaster-Carr, item 9438K1.

It's on it's way back to Dead Air. I soaked it, froze it, heated it...... nothing worked.

Oddly enough I was asked to send the whole suppressor back, not just the mount. Perhaps others with more knowledge could explain that part to me.

I always recommend antiseize on barrel threads that attach suppressors or brakes.

Just my $0.02

My 03 recommended anti-seize as well, and IIRC the manual that came with both my SWR Octane and YHM Mite did also

Good idea. That is something I have not been in the habit of doing.

Another anti-seize user here. I keep a tube in my range bag and apply it liberally before anything gets threaded on a barrel.

And I've STILL had to occasionally use a wrench to get a suppressor off my barrel. Even though I never shoot fast enough for my suppressors to get much beyond "pleasantly toasty".
