Question Please explain "Raised Mounts"

[USMC06RET]

The included pictures are simply examples.

I see a lot of raised mounts for different kinds of optics. The only explanations I can come up with for their purpose are:

1.) On long guns and shotguns: You would want to raise an optic: When you are resting your face on the rear stock, your eye is not at the level of an unraised optic.

2.) On a side arm: The iron sights get in the way of an unraised optic.

I haven't experienced any of these issues so, I would appreciate knowing if I have missed something about the usefulness of raised mounts?

At CQB distances, bringing the rifle up for a quick shot brings the optic into view without a cheekweld stance. Also, a raised optic allows your head to stay on a swivel without having to turn entire torso. Throw in NVG's, gasmask, etc and the high mount makes more sense.

For pistols, with the technological advances, most mounts, setups, etc have gone away from higher mounted optics. To cowitness, most now use suppressor height sights and an RDO mounted depressed into the slide.

Also, for pistols, some shooters prefer the slightly higher optic mounted to the frame instead of the slide because it prevents the optic from reciprocating with each shot. This provides a more stable, clear sight picture when the rdo does not move.

Yeah, that all makes a lot of sense. Thank for explaining.
