Just did the basics on my M390 mule, nothing crazy or fancy. Installed a set of orange G10 Halpern scales, made my own kydex sheath, and then attached it to an ESEE 3 molle nylon back. All came together great and I am very happy with how it all came out. This one will ride with me on my LBE vest. Here are a few pics that I snapped, hope they turn out ok. Thanks! :D
