Best Moderator for Brocock Compatto

If silence is the name of your game, you might want to take a look at this:

That is the best answer I've got for you I'm afraid. I hope it helps though.  

DonnyFL is the only moderator I buy from. I've tried them all and Donny's are the best made...hands down! I bought one of the first he ever made and still have it.

Standard Huggett Usually does a pretty good job. What caliber is your Compatto?

I had a .22 Compatto MK1, unregulated. Came with a small Huggett from AoA. It was very backyard friendly. 

Have only used DonnyFL since, but wouldn’t hesitate to use that Huggett again. So, I wonder if there is something else going on? Have you had someone else shoot the gun and stand a few feet away yourself? 

In either case, there’s no substitute for volume, go bigger, maybe a Tatsu or Sumo. 

I have a DonnyFl Tanto on my .22 Compatto and it’s definitely backyard friendly. It’s currently on my newest toy. But I will be ordering another Tanto.
