So what are you looking for? You have a lot of properties to decide on length, solid design or take apart, quietest, warranty. you sacrifice some things for others. the quietest ones are generally longer or made by someone other than a major manufacturer 22 cal is a dirty ammo so you might want to consider one that comes apart but that would not mean the quietest I am doing research and development for supressors right now and have found that there are hundreds of designs for baffles and some of them simply don't work worth a darn but the best designs are too expensive to mass produce and still sell for a profit. Small companies that have little overhead can make a great supressor and make it profitable but they sell so fast that getting one is near impossable without waiting for it to be made.
