You want to use a suppressor on an SBR? Are you aware of the legality/tax stamps?
Yes, I already have a registered SBR lower and I already own a SS Sparrow suppressor. I figured why not? That would make a cool .22lr plinker and I can get a little more "me time" with my AR.
I looked on CMMG's site and while they dont sell a SBR upper I can get a 6.5" barrel/bcg/charge handle for $280. I already have a stripped upper reciever at home so I guess all I'll need is a FF tube and some irons.
I'll check out Taccom now.
