The reason your gun doesn't come with tear down instructions is because the manufacturer doesn't want you to tear it down. It's a dangerous proceedure, and they could possibly be held liable in some way if you or anybody got hurt taking it apart. Most manufacturers will void any kind of warrenty if not serviced by 'their technicians/ rep's etc. My advice,.....Just shoot it as much as you can to break it in. The GTA is an awesome source of information on this subject, so read up as much as you can before you decide to tear into!!! Best of Luck,....and welcome to the GTA!!!! tjk
