So I was at the range today and I decided to take my red dot off to practice on my buis. Unfortunately, it was shooting not only low, but to the right.

Which adjustments do I need to tinker with to get it on target?

can you be more specific? 100 yrd zero, 200 yrd? What type of BUIS?

You need to adjust your windage knob so that it moves the rear sight hole to the left, and you need to raise your front sight post with the fsp tool or a punch that can press down the detent so you can spin it.

Also, unlike a lot of parallax-free red dot sights, you need to maintain a consistent cheek-weld with the rifle when you shoot through the irons.

Speaking of BUIS... How much are those flip ones? It also comes with adjustable range setting. Looking for one of those cause my BUIS is getting in the way of my EOTech when I don't want it to.

Try 300 if you got the BUIS with the settings. I think 300 is standard, unless I'm wrong. Correct me if I am

300 is considered to be the standard battle zero. At least for the US Army.

Take a pic of the target so that we can see where your rounds are hitting..

if it's low and to the right, try 2-left and 2-down.. and go from there..

Adjust the front sight for elevation, the rear sight for windage.

That's a good resource. I also found the Bushmaster operating manual to be useful for a lot of things related to ARs. Zeroing procedures found on pages 19-21:

Lengthy .pdf but worth the download.
