    Static alignment should be well enough to prevent binding and wear on one part, or location more than the other if everything is in specifications in it's normal state. Dynamic alignment is done by trending a wear pattern from actual usage that shows that the alignment needs to be shifted by a certain degree and offset from that normal state. Finding the balance is a study, patterns can happen and come and go. Unfortunately, many manufacturers realize this and recommend replacement schedules in higher frequency instead of analyzing data they probably already have to save to a few dollars.

    This is correct.
    I just got back from a 2 day CQB Clinic and the rifle performed very well in all conditions including rain and mud with a new gas tube installed.
    I had 2 malfunctions both while laying down in the modified prone position (strong side on the ground with the ejection port facing the ground).
    The first was due to my arm covering the ejection port causing a stovepipe.
    The second was me not seating the mag well enough and manually attempting to clear the round causing a double feed.
    It is not me pictured below but it gives a good idea as to the position we were shooting from.
