They fill a niche for guys wearing gas masks, respirators, or guys doing passsive aiming through their nods. I’ve used one for passive aiming and it is good for that. However I think because CAG has used them and someone mentioned it now everyone is all about them. For 99% of the people out there they are not needed.


The cons with them are:
1 an increased height over bore so now your in close CQB holdovers are ridiculous. For all the swat guys you see using them it’s not good considering they’re expected to make low percentage shots. With a single dot to make a shot to the ocular box you’re holding your dot over the person’s head as opposed to holding hairline.

2 Shooting through a port or under a vehicle can now be more difficult because you may see through a port but your muzzle is obstructed.

3 your zero is no longer a 50/200 or follows the normal trajectory because height over bore plays into that.

4 Prone is less comfortable and not as repeatable because of the lack of a chin weld. If you’re using a high scope mount and following the trend of everything must be first focal plane you’ll have more eyebox issues. FFP have tigher eye boxes and this issue is exacerbated when you don’t have a consistent cheekweld
