What is high port with a rifle?

Answer 1

Strong arm's forearm straight up, hand on grip, finger off trigger, firearm on safe, muzzle up in the air.

I find it's helpful when moving and reloading to tuck the stock between my tricep/elbow and body to really lock it down. Otherwise, the gun is moving around and the hand with the fresh mag is moving around and when running it's tough to line them up together. While reloading the magazine well and magazine are right in the line of vision (work space) where they should be.

High port doesn't work all the time. I use it for running with a rifle as it allows for me to do so one handed and the rifle isn't banging around on my sling. But at the same time, my sling preference (two point) isn't ideal for that unless I keep the sling solely around my neck while moving (not enough slack otherwise).

Running low ready is fine sometimes, depends on the situation just like anything else.

Answer 2

Rifle held with two hands, in front of the chest, at a 45' angle to the body. Held this way while running.
