Risking the Snickers and Laughs (BUIS Site Question)

AR/M4 AR General Discussion
1

I just purchased a set of BUIS, and I am realizing how ignorant I am about getting an accurate site picture using military style irons. I grew up shooting long range with scopes on high powered bolt rifles, and fixed iron sites for close range on a 30x30. Both of these site arrangements come natural to me, but I just mounted my BUIS on my m&p15, and realized I don’t know enough about this site system to zero, or to accurately aim this firearm.

I used the site search option, and didn’t find anything this basic. I found info on zeroing, but without knowing where in my site picture I want the front post to sit, I have no idea where to start.

Can anyone give me links of accurate site pictures? Or basic info.

I realize this is pretty basic, and most of you are probably snickering, but I have always gotten a great response from this site, and have used it as my primary resource since purchasing my AR15.

Thanks in advance for any info.

Are you asking what the sight picture you are supposed to see is? Relation of FSP inside ghost ring? Focus on target or FSP? That sort of thing?

exactly

Not a dumb question. I think someone has something formal written up and would better serve you and the community here. They will be along shortly I assume. It might be beneficial to have something like this stickied. Maybe a red-dot sight picture explanation as well in terms of focus point being the dot or the target etc. Standby for someone more knowledgeable. :cool:

Thanks guys.
So basically the top of the post is either immediately on, or slightly below the point of impact (which is what I assumed).

So the front site I bought was a HK style. But I still get the idea, in regards to the post.

If this becomes a sticky of the bare basics, which article is considered the best in regards to zeroing irons?

There’s already a sticky about zeroing “LTC Chuck Santose - An Improved Battlesight Zero” tacked in the Knowledge Base Threads, take a look at the pdf link on page two of that article.

An Improved Battlesight Zero - page 2 link

Thank you. I was having a lot of problems finding that.

LTC Santose is the way to to go for irons - he is still active on the old AR15-L list. Always a pleasure when he chimes in. Pretty on for zero magnification red-dots as well.
