The cam pin is indeed disengaging. However, this is a result of an out of spec receiver, and not an out of spec cam pin. And as many have already stated, I'm not trying to bash the product. I also bought one myself. My concern is that changing the cam pins is just a quick fix. Will the extra play in the carrier group cause excess wear of the receiver? Or to the carrier group itself? I don't know, and I'm not going to pretend that I do. Just voicing my concern.
