300 whisper Sig 556

[anubismp]

I'm new here and am looking at doing a bbl conversion on my sig 556 classic. I like the idea of the Whisper and I would like to try to do my own work but I'm unsure how feasible that will be. I saw the 552 conversion and I like the idea but I cant SBR in WA so I'll be trying for a 16". Please throw me ideas for bbl makers, gas plug ideas and the like. I'd be shooting suppressed when out of state so I'd like it to be mostly a suppressed sub load gun.
