    At what range do you zero your AR and why?

    50/200 yards because it's the flatest trajectory from 0 to about 230 yards.

    50 yard your on my 5.56/.223 ars. For center of mass shooting to 0 to 300 yard shooting.

    100 yards for anything precision......

    100yards on the acog or will be. Not sure what im going to do with buis prolly 300yd. In the past ive always used 100yards but that was in texas in scrub brush where a 75-100 was pretty much it.

    50/200 on 1 of them, 100 yrd zero on my scoped AR, 50 yrds on the SBR but I have no idea how much drop it will have at 100 yards since it is such a short barrel I need to do a Chronograph check on it and see where its at . and a 200 zero .223 on my bolt gun

    100 since the scope is bullet compensated from 100-600

    50 Yards is excellent for a tactical weapon. For precision varmint/predator rifles 100 yards is preferred due to the fact that most ballistics charts are based on a 100 yard zero data. Along with the wind charts for the 5.56 are also based on 100 yard zero data.

    dont want to hijack your thread but i figured why make another one on this topic.


    im going to be getting 2 new scopes shortly, a nikon p223, and a leopuld vxr.
    theses 2 scopes will be getting placed on my wifes, and my AR's. i have the irons set at the mentioned 50/200 zero. i know i need to set my scope the p223 at 100 yards for the BDC to be close to effective. whats going to be a good zero for hers? so far she shoots out to 50 yards. im sure with the scope she will at least attempt 100yards. perhaps if shes brave i can get her to shoot 200. but that will only be once in awhile. so mostly it will need to cover 50 to 100yards

    Zero at 50 yards will be 1-2" high at 25 and low at 100. Correct?

    I zeroed my carbine RDS at 25 yards and iron sights at 50.

    Q and Jon what did you think about the 36/300 that was discussed on that DVD?

    jjfuller1, I would zero hers at whatever requires the least need for holdover. I'd think it would be easier for her.

    Kinda odd that if fell off at a 12" barrel length :confused:, also almost hard to believe only 500-550 fps difference between a 7.5" barrel and a 16" barrel . I would have guessed more around 800 fps to be honest , I will take the chrono out with me next time I go and I will try a couple diferent brands and write them all down on each barrel

    My C-more is set at a 25 yard zero. I know my trajectory will equal my POI/POA error out to 375 yards.

    here's a diagram of my reasoning. I teach both the 50 and 25 yard zeros. I choose the 25, but let the student choose his/her zero.

    I like this image. Would you happen to have 1 for a 50 yard zero?

    I'm currently zero'd at 25 but am not completely set on it. I gonna try out a 50 yard and see how I like that.

    I guess it's a Marine thing. It's supposed to zero your AR so that there is no holdover out to 300-400 yards. That section is very interesting.

    well, sort of. you are correct that we used 36/300 zeros..we sighted in at 36 yards. but for shooting, the closest qualification target is 200 yards. goes 200, 300, 500. we did other training with shorter distances, however we always used the same zero... incorrect on holdover. we learn to make sight adjustments ;)
