I was cleaning my gun, and also decided to do Bigtacos trigger mod, but after all was said and done, I cannot figure out where the hell the spring #20 fits into the trigger #17 and the drop safety #25... I am probably just frustrated and will figure it out tomorrow, but tonight it is really getting to me. Can someone please send me step by step where it goes? I just cannot get it. Pictures if possible would be awsome. If you need photos I can load some. Please help! Ps, I have the M-40 Edited: I got it back together, Thanks to the sear assembly guide! Thanks guys.
