For fun I'm wondering what other platforms I could use my HK SD suppressor on? Being a B&T person the APC9 I got. I also know there is the ILWT barrel for the MPX that I have but have never got around to building, but will. I think there was an AR one mentioned by P220Smudge?? like broadrivertactical, but they never have anything available when i looked. Other options?
