Can't even install - Manticore Arms Raptor Charging Handle for Steyr AUG

I received this product a while ago but as I'm active duty military I wasn't home to install until recently and was supremely disappointed when the product didn't even fit. The hole drilled for the roll pin was not lined up and unlike the individual in the other review, even using my original roll pin it would not fit. On top of that, some of the material inside the charging handle was broken off, not in a way that obscures me any further from installing the charging handle but it further proves the quality control issue with these charging handles. It's a shame that this is one of, if not THE, cheapest option for an AUG charging handle upgrade but I suppose you get what you pay for.
