Which is the point. It's not good, it meets the spec.

Sometimes the spec means it's overbuilt compared to a civilian version. A lot of the time someone not-the-government is willing to pay more for different features than the spec.

An AR trigger going to a 19 year old just out of basic does not need to be match quality. Most of them suck as marksmen. Most of them will rarely shoot a rifle after basic because their MOS doesn't require it, and they don't need a good (read: more expensive) trigger to qualify for basic competence.
