Will: You may want to contact S&W about that problem, I just read a thread on another site where some had the same issue and S&W replaced it for free.

Thanks for the link. I don't have any where near that round count down range, but my targets look exactly the same. I will give S&W a call tomorrow and see what they can do for me. The only thing they might give me trouble about is the fact that I installed an Osprey Arms OPS-416 piston system on this upper, and man does it run smooth, clean and cool. Its just the damn keyhole issue that annoys the crap out of me. Thanks again.
