Good but not perfect - GG&G Benelli Charging Handle for M1, M2, M3, M4

On theory it's a solid product but the one I received from OP actually broke on me the first time I had it out. I was extremely excited to shoot my Benelli M4 for the first time and the charging handle broke on me within the first few rounds. My Benelli was out the rest of the day.
I contacted GG&G, they sent me a replacement and told me that had a heat treat problem with a batch of these. The new one hasn't failed me yet.
I really do like this product but that first issue has put a bad taste in my mouth.
