Missing parts - JE Machine Tech AR-15 Lower Parts Kit

You get what you pay for. The trigger guard roll pin was missing. Parts felt gritty and crude compared to other lower parts kits. The trigger has a nice clean pull. There was also an extra magazine release spring and disconnector spring. The pivot pin detents and safety detent were a silver color (not the usual brass color). I suspect this had something to do with the grittiness (even after using lithium grease).
