Traded two markers, two barrels and cash for a dm13. His communication was excellent and the entire process went smooth. Only issue was when I received the marker it was leaking. It had significant wear on the bolt which in turn was causing the leak. (Had this verified by a DM tech, Matt, at Paintball Asylum in Louisville, KY). I was not informed about this wear prior to the transaction and informed areo of the situation. We could not come to agreement on how to fix the problem and now I am stuck with a leaking dm that needs a new bolt. Communication- 10/10, shipping- 10/10 but description of product- 4/10. Overall the transaction seemed to go smooth until I received product. Would not deal with again or recommend.
