I just recently picked up a dm7 here on nation. I had a dm6 when they first came out and I loved it. But I have had another dm since and I missed how they shot... I had to pick one up and I did. Now I want to tune it right. Just now exactly sure what I should have my settings at dwell, lpr, etc... sorry it theres a lot of these threads out. I usually just take my guns to my pro shop but I'd like to work on this marker myself. Thanks ahead of time guys!
