It is currently sitting in my trunk, with a dead round in the chamber. I can't get it to go through more than one magazine without malfunctioning. I've swapped out springs, buffers, and triggers, it still jams the spent case sideways into the chamber. At this point, I think the lower receiver is out of spec. When I run the complete upper on another lower, it's like butter. The Spikes 9mm AR uses the same magazines, and ran flawlessly yesterday. I'm trying one more thing with this lower, then I'm tearing it apart and getting another dedicated 9mm lower. I'm going to use my known good upper on it. If it continues to flake, it's going to be a paperweight. Or I'll send it to my smith, wait two months and spend $$$ on something that should be right the first time.
