I want to make a 30 cal can for my 300 Blackout and I have some questions. I'm leaning towards the FTN 4.5 or 5 but not sure which is better. Sound is important but durability is probably more important. My biggest question is how to mount it. The instructions say to use a 1/2-28 thread adapter but my pistol is 5/8-24. The only 5/8-24 adapter I can find is aluminum which I assume will work but I'm not sure. Also, is there any way to attach it to a SilencerCo ASR muzzle device? Most of my guns already have ASR breaks on them and it would be awesome to be able to quick attach them.
