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.
Veritasium(?) has a video about jerry cans that boils down to "Surprise! The Germans over-engineered the crap out of these!" and how most modern ones aren't as good because its significantly cheaper to make ones that just look similar.
Still better than the plastic ones usually but you kind of have to hunt for the older style at this point to get the best of the best.
