The upgraded core for the AAC Prodigy is a great sounding can but it's still an aluminum mono core. It is difficult to get apart once it fills with lead and its cleaning options are limited. The Element is SS and Ti with K baffles which are also hard to get apart once filled but at least they are more durable to clean. If I purchased an AAC product for a .22, it would be their Element, if I could get pass the fact it looks like a sewer pipe.
Gemtech is a good company. Phil Dater is an authority on suppressors and is also a great guy. He does not own the company anymore but works in their custom shop. I have experienced his CS and he is very fair. They had a limited run of their Alpine in SS a while back with easy-to-clean M baffles. I almost got that one or the G5-22 if it came thinner SS baffles.
SWR/Silencerco CS is #1. Henry, Matt, Josh, Mike and Garry are very driven to produce the best quality CS, products, industry, commercial, and political relationships. I would not be surprised if they change the industry and eventually get suppressors pulled from the registry within 5 yrs.
I've had multiple experiences with them and their CS. I had the Spectre, Trident, HEMSII, SS Sparrow and Osprey. I put 60K through my Spectre I. I never scrubbed the thing. I just took it apart, threw it in "The Dip" over night, and wiped off the baffles. You can do that with a SS or Ti can, not with carbon steel or aluminum.
Another great company is Liberty Suppressors. I've had David work on several unique projects. Their Kodiac, Kodiac TL or Essence are amazing. They have the lowest blow back of the bunch. They are great for suppression, materials and will leave the action and mags the cleanest out of all the choices. The are also SS mono cores and can be difficult to remove but Liberty gives free tools to help. If you want one of the most versatile cans around, look at their Mystic. It handles everything.
I've also done T&E for Thompson Machine. Richard and Brooks have great service and products for their budget price point. If you want an aluminum can, I recommend them highly.
Remember a silencers has little to no resale value and they are a pain to get. Get an heirloom quality one. Get the best quality one you can afford.
I'm not a rich guy. As long as suppressors are tittle II, I can't afford to throw cash away on disposable suppressors. I would like my suppressors to save the hearing of my grand kids one day.
I'm no expert, I just have over 20 stamps and my 10 yrs experience to share. I hope it helps. YMMV.
