I just received some. I demo'd it last evening. Sound reduction was fantastic. Hosts included a Walther P22Q, Ruger 22/45 Lite, and a Ruger 10/22. CCI Subsonic ammo used. No perceivable FOP. Hearing safe all day long. I did not use high velocity ammo yet so I cannot comment on the reduction in noise on that. The hosts all cycled properly. The can itself is very well made, very easily taken apart and serviced. It is also very easily reassembled. It is a 1" can so most stock sights can be used. It is not too heavy either. Solid construction and priced right. Include the takedown tool. I would recommend them. If anyone is in the CT area feel free to check it out.
