The DM8 is a badass gun IMO. I put a warped sports trigger, virtue board, CP front plug and ASA, and the DM9 eyepipe and never had any issues with it until I hung it up until recently, just gonna put new O-rings in it and go.
DMs are finicky in the cold cuz of the spool valve, hence why I have an 05 Ego and an E2 autococker as a back up.
