How to Zero your AR15 / M4 / M16A2 Platform: Mechanical Zero & the 25m Target
How to Zero you AR15 / M4 Platform: Mechanical Zero & the 25m Target I have gotten a great deal of requests from new shooters who have obtained an AR platform and are questioning how to sight it in, I explain the approach that I discovered even though I was in the Army. How correct this process? Well the only way to demonstrate this is by splitting taking part in cards which I have completed from 20 feet out to 300 feet away (even left & correct handed). The evidence is in the pudding. www.youtube.com www.youtube.com www.youtube.com www.youtube.com www.youtube.com There are several diverse types of sights & even diverse zeroing processes & targets & processes, so preserve in brain this is NOT an all inclusive class but it will give the simple actions on how to set your AR rig for a problem known as “Mechanical Zero” and explain how to use the M16A2 25m Zero target I realized in the US Army. The 25m Zero Target allows the shooter to ‘zero’ in the sights for that specific shooter so they can properly engage targets at 300m (and longer). Right here is a hyperlink to a pdf file of the 25m target you can download… www.bobdbob.com All info is for education/informational purposes only. I hope you take pleasure in this vid and understand how to zero your AR platform. 
Steve PS Do NOT get hung up on utilizing an M4 25m target or the M16 25m target – they are basically the very same but 1 the boxes or grids are somewhat larger. Heck I have employed hand drawn grid paper to zero & it worked fine. Reality stays you still ‘walk’ your groups in by …
@TheHobbyistChannel
The small and large apertures are NOT on the same axis, so zeroing your small aperture at a certain distance will not result in the same zero for the large aperture.
If you zero your SMALL aperture at 25M/300M, the LARGE one will automatically be zeroed at 200M. That’s how the sights are designed.
Use the target shown to sight in the small aperture at 25M and the large one should have a 200M zero.
Hope this helps
@dreior If the front sight physically moves up, the point of impact moves down. The arrow represents what will happen to the point of impact, NOT the sight post.
So the way I understand it is the you can use the target you show here at 200 yards, but the AR will be zeroed for 300?
Excellent
Thanks
starting at 5:10 the front sight is being mooved counterclocwise to bring up, while the arrow on the front sight indicates clockwise for up; confusing! anybody able to clarify?
Great information however, just for clarification, when you use the M4 25m target to sight in the AR15 to mechanical zero which aperture do you use. In your video you switch to the large aperture right before you talk about the target. But you do not specifically say which aperture to use when shooting at the target.
I went to a rifle workshop at a gun show and thet showed how to zero in with only 2 shots, just by shooting and placing the scope reticle on the hit and repeating until accurate…dunno if anyone else does this but it works for me
thank you very much… greatings
what is the size of the squares to have the zero?
Fantastic Video. You really helped me out man! Thank you
Great video; very informative and easy to follow. I am helping some friends new to shooting, and this was just what we needed!
Good video
@farmlovingmemories or a lav mic.
Thank you for this video. I’m sighting in my new Sig516 AR today and this was very helpful
@SafeArmsReview how do you take off the carrying handle on the ar 15? or do you already have a video on that? and if so please link it plz
thank you.
@SafeArmsReview
For 6-inch barrel what will be the initial zeroing distance? shall I divide the 6 with 20 the full lenght M16 barrel then divide the quotient with 25 meters? thank you.
That was excellent!
Thank you great video.
@kyokushin1 If you check the description box you will links to videos where I split playing cards at distances from 20ft to 300ft using this method of zeroing. Sorry for the confusion.
If you zero using the 25m target you rig will be set for targets up to 300.
I hope this helps.
Great video. Can the rear sight elevation be used without adjusting the front?
