Any tips for new army weapons (m4) qualifications?

Steady shooting position, bone support, sight alignment, Sight Picture, Natural Repository Pause, Slow steady squeeze,

tips and tricks are all fine and dandy but practicing and building fundamentals is key to mastery of repetitive actions

Shooting is an acquired skill, qualifying once a year and expecting much is a real stretch, bottom line they don’t shoot near enough. Direct combat MOS should shoot at least monthly, imo of course, and the lack of skill is why they’re always searching for a new magic shooting platform that will make up for the lack of basics skills. If you don’t shoot often you won’t be skilled, muscle memory is a real thing, they’ll spend trillions on new toys but invest little in the soldiers and Marines whose life depends on that skill.

If your shot grouping is wide, bullets going left to right, it's a trigger squeeze problem. If your shot grouping is up and down, it's a breathing problem. If you are grouping ok, but it is in different spots without adjustments, it's a sight picture problem. Consistency is the name of the game, same grip, same squeeze, leg goes in the same place, etc.
