Following the successful launch of the MP7 SMG, TM is going to roll out a series of automatic SMGs based on the MP7 mechbox. The MP7 mechbox has an architecture almost totally different from the “regular” mechboxes. This guide aims at showing you how to assemble and troubleshoot this new mechbox. Instead of solely focusing on gear shimming, we pay close attention to MANY small and frequently-ignored details (in addition to shimming) that are in fact critical to the smooth operation of your SMG mechbox. We also guide you through the steps required for achieving the best possible air sealing and compression effect.
