I have a customer that disassembled the trigger assembly on his SL-7 and can't seem to figure out how all the springs/buffer go back in. Do any of you have some insight as to how to put it all back together? Tried going through HK and after waiting months....they kept sending me the same Numrich parts schematic that only shows the trigger assembly, none of the inner components. They said they needed to contact Germany in hopes of getting the information we need and I have yet to hear back. I'm hoping one of you have been through this before and can shed a little light for me. Thanks!
