Then it is perfectly fine according to your results.
It's hard to tell what someone is describing on the internet. One person's "click" is very minor, another's may be very major. People have different ideas, sensitivities, observations and interpretations.
That's why I like objective type tests. I've seen AR's where the carrier would not slide down even when completely vertical. You'd have to barely touch it with your finger to close it. Didn't show when in the rifle due to buffer spring pushing it down. It's not good to add an extra obstacle to going into battery. The AR-15 doesn't have much mass or force going into battery. Not like an AK that has a long stroke and huge carrier mass that really slams the round home. You can see this when you put a fully loaded 30rd mag into the AR, and then hit the bolt release on a relatively new mag (or even just a regular mag). Doesn't lock nearly as fast as it does on the last few rounds. On it's own it won't cause a failure, but figure this. You have a full mag, a worn out buffer spring, a dirty receiver extension, a dirty cruddy action where the lube has dried up or burned up, a filthy chamber, the ammunition might not be slick and polished......ADD up all these factors, and the action is not closing as smoothly or as quickly as it should. Losing momentum, which can lead to a round not seating all the way. Not likely, but possible. You don't want a stiff gas tube on top of that adding more resistance.
A lot of factory built guns fail the 45 degree test.
