I bought a SilencerCo Hybrid 46 from Fuquay Gun on December 6 and got the call to pick it up July 3, 6.5 months. This was my first suppressor so I excitedly ran down there this afternoon to collect. Since this was my first suppressor, I had a lot of questions about the adapters and threaded barrels. I brought my G19 and Sig M400. Things are pretty crazy down there, the shelves are nearly bare and it was a Sunday, so I guess I should have come at a different time. The line was out the door, I had to wait for my turn. They had the SilencerCo muzzle brake with 1/2 - 28 threads and they put it on the M400. But they didn't have the part I needed to attach the Hybrid to the M400. They looked it up and told me what I needed. I got home and couldn't find the paper, but I remember he said that the important thing was that it was the "bravo" one. They sold me a threaded barrel for the G19, and I thought I'd be able to screw the Hybrid onto the G19, and when I got home I discovered I couldn't. I know, I'm a newbie to this world. But could someone point me to the parts I need to use this suppressor?
