so i was thinking about pickinking up a 223 suppressor for my mini and a 22 bolt. I was wondering what it took to run subsonic ammo out of a sbr mini? if you could run both subsonic and supersonic ammo with the same gas system? what would be ideal is if you could adjust the gas system on the fly so you had the option to work the bolt manually if you wanted to go really silent. any help on this would be greatly appricated.
