Ok guys I built my first AR for christmas its a 16" mid with magpul MOE hand guard. I have been having some fun with it this last two weeks about 1500 rounds of fun. Well this evening I took off the hand guards for a good detail cleaning. And found that the two large tabs that hold the top piece of the hand guard to the plate at the gas block are broke off. It will still hold on by the two smaller tabs. I have heard a lot of good things about magpul and was wondering if anyone else has had problems. Maybe I just got a defective one? I should add I got the hand guard as part of my complete kit so who should I call first Del-ton who I got the kit from or Magpul?
