Haven't seen much info on 308 sbr. I currently have mega arms midlength 308 16". Just put an order on a yhm ss can. So the sbr will be shot 50/50 w/wo the can. I'd like a new upper instead of sending adco to chop it down. Any recs on complete uppers if any company offers. Or any recs in general. Don't really have much a clue on 308 sbr for cans. Edit: nm, I just realized I'll probably have to go custom. Since I'll need a new mega upper indefinitely anyways. Thanks guys
