I bought the cameron 3D desing from Ebay for my new wood stock .22 AVA. It’s shorter and lighther and also has the most affordable price of all the other options available in the market. According to a independent youtube comparison sound test it works as good as the more fancy and expensive moderators of the market that cost 3 times his price.
I've had very good luck with my all in one moderator. Sound alike you don't want to hear "it supports the barrel" but it does.
I have really good db drop and it completely changes the report of the shot. My favorite part is how it weighs 1.2oz, and only adds 2.6" to the overall length. Not 1.5" for the adapter and then another 4-7" for a moderator.
