I was at a gunsmith shop today and he demoed a integrally suppressed 10/22 and muzzle attached 10/22. The integral one was quieter by a decent bit. He said the guy who makes them for him can do either for any rifle centerfire or rimfire. Yes the operation is on the up and up. I haven't seen any intregral centerfire here so I thought I would seek out opinions between the two. I think it was 650 to get the 10/22 integrally suppressed and 450 for the muzzle attached model, not including ATF tax fee. I figure there is a reason why most go with muzzle attached, but I would like to hear the reasoning.
