From practical experience, I can endorse reliability enhancements I, II and IV. I feel that III is to some extent a matter of personal choice once the lubricant is of sufficient quality to make the gun run.
As far as the accuracy enhancements, I’ll support I with the caveat of “If you use an optic.” I can make an argument for Joe Average not having an optic on his SHTF gun that goes along the lines of “normally will have insufficient training for effective use”. I don’t support II unless your AR is for competition. I’ll have to take their word on III. I unfortunately don’t get any opportunity for night shooting.
