Hi, I bought a new 10FP in .223. I tried adjusting the trigger pull and it can't be loosened. It sems as though the spring is tweaked or something. I took the trigger all the way off and it still wouldn't thread in past a certain point. Anyone ever run into this? Something I may be doing wrong? I will probably call SSS on moday, but I was hoping to play with it today. Let me know if anyone has any insight for me...Thanks.
