Hey guys I had a problem that came up when in the process of putting togther my sbr build. I originally wanted a dd mk18 upper. However, after speaking to a few people I am wondering whether I should go for the dd mk18 which has a 10.3" barrel, or buy a 10.5" mk18 upper buy another manufacturer. I guess the question is, can I reliably suppress a 10.3" barrel? I have a YHM phantom LT on a form 4 to mount onto the sbr. Anybody have any hands on with this setup or a similar set up?
