Yeah, you have to get very low on them, but I find it doable just not comfortable. To me it is a fine tradeoff for the lower cost, lower snagging, and quick takeup.Some people like the XS sights. I personally will never use them again. All they are are big dot sights for your AR which itself isn't a bad thing. What is bad about them is how low they are. It is near impossible to keep the same cheek weld that you normally use and then rock the gun over and have a correct sight picture. They are far too low for my tastes, and ok ow each o my teammates who have tried them feel the same way.
