下面是我给FA写的email。。。反正我是找不出来什么地方不对，安装前反复读了instruction，毕竟当年做了多年的实验。已经寄回FA了，看看会怎么样
Hello Franklin Armory,
I just bought a BFSIII binary trigger from Walsh Gun and Tackle. I tried to install it to my Sig MPX SBR last night but couldn't get the trigger to pass the initial function check. The trigger was tested fine as uninstalled trigger - IDS could be pushed forward and when I pushed down on rear of disconnector, IDS slipped under the disconnector. However, no matter what I tried, it only functioned as semi (before safety installed) in the MPX lower. I took trigger out and pulled it apart; the IDS spring was fine without damage, just looked like the spare. I oiled everything all up and put it back together carefully and tested again, still no binary function. Actually when I held the trigger back, the hammer could not re-cock on the disconnector. I had to release the trigger a bit to let the hammer re-cock, but it functioned as semi. Replaced IDS spring with the spare, no luck and still semi only. Installed the trigger in another AR15 lower (Spikes Tactical the Jack), still semi only and no binary function. I even tried to installed the safety and checked again, but still nothing worked, and when holding down the trigger it was very hard to pull the charging handle...

. semi only on both MPX and a Spikes tac Jack lower... 网上查了查居然不少同志都是这样！！都是寄回去修，很多能看出来打磨了disconnector。。。 正在联系寄回给FA修呢。LZ你的装上就work吗？
