I was hoping my can that I use on my 300 blackout would work with my 300wsm rifle I am building. Well someone else is building it. So E-mailed Mike Smith at AAC about it and with in 10 min I got ALL the info I need . This is not the first time this has Happened. Great customer service. This will be my 4th AAC suppressor. Hope it ok to post about good experience here.
