Bobby B: im confused on the reason of 8/3 plus 1, or 6/3 plus 1. what was the
reason again....thank you
Mr2fierce: bobby the bullet doesnt travel straight going out of the barrel, sights and
barrel isnt perfectly pararel
Bobby B: so your saying 36 yrds , bullet will not drop if you jump out to 300 yrds?
Bobby B: i thought you zero and when your done. turn your knob back to 6/3? and if
you are zeroed for 25meters, why would you already be zeroed at 300
without any other adjustments. thanks
BL Ranch: For some reason I am not able to approve all comments on this video. I'm
not sure why, so please don't think I'm ignoring you all; glad this video
has been so helpful. I do have a newer version on my channel if you are all
interested. It's much more to the point and simple.
darwinfoto09: Thanks for posting this :)
James Dale Reed: thanks for you video It helped me a lot for getting my AR-15 Sighted in .
BL Ranch: All other fine elevation and windage adjustments are made from that set
BZO. If you get your windage and elevation out of whack, you can go back
and apply those clicks you recorded from your initial BZO session and that
will get your rifle back to it's set point. You should never really have to
mess with the front sight post again after the initial BZO unless it get
damaged or you are shooting on another rifle.
ThermalSh0ck: can you use this method for a aimpoint optic?
BL Ranch: That's an excellent point. The rear sites, as good as they are, aren't
entirely perfect. It's more accurate to rely on a click count than to use
the center index line as the center start point. From a tactical
perspective, using the click count method allows you to re-establish a BZO
in low light conditions.
Hayseed1776: Hello great vid ,,but my RRA ar has a 6/3 not 8/3 on the side of the rear
site is it the same.? my front site is all the way up and I used the rear
site for the up and down too along with the left and right is the wrong ?
overload889: Thats a really handy video. Unfortunately the BZO target link isnt working
for me. I tried to save the picture but the web page locks up everytime.
1039sflem: I tried to zero my AR-15 a couple of weeks ago. I had trouble getting
consistent groups. In the end, my rear sight is only about 1/4 the way from
the far left side travel stop. Is this normal or should I try again. I did
finally get some decent shots on target, but at my age, my eyes just to
focus like they used to. Do you have any suggestions?
rls303: Been all over Y/Tube... This by-far is the best on what i needed...Thanks
BL Ranch: Absolutely. Good catch. You will want to make all of your elevation
adjustments from the front site post initially during the BZO phase. All
windage adjustments are made from the rear sight windage knob. Once your
BZO is established you can make all the minor elevation corrections with
the rear sight elevation knob. By recording your initial BZO settings you
can get back to your set point without having to do the guess work. I
periodically set mechanical zero on my rear sight and apply my...
BL Ranch: ...that it will be right on or very close to 300 yards/meters.
BL Ranch: Any time. I'm very cognizant of that when I script out the videos. I like
to convey the pertinent information without a lot of distraction.
BL Ranch: This was shot in south eastern Washington.
BL Ranch: Haha. I threw that in there as a good "tie in".
rls303: Sounds like a great way to get sidetracked:) Had to comeback to this video
after taking my rear sight off to get a scope on"My memory ain't what it
used to be.. lol Looking forward to the next one. Take care
MR-FLIP: what if im using a flip up sight magpul mbus gen 2 whats a m-zero for it
BL Ranch: For example. My BZO for that rifle (one in the video) is 38 right, 6
clockwise. This means from the farthest left position on my rear sight I
apply 38 clicks to the right and have my front sight post turned 6 notches
clockwise from the flush position. I keep this record on the back of one of
my business cards in the buttstock compartment.
BL Ranch: Here's a point of clarification for users of this tutorial. If you are
planning to zero your rifle in meters, set the target 25 meters from the
muzzle of your weapon. Set your rear sight elevation knob to 8/3 or 6/3 +1.
If you are zeroing for yards, like I was doing in this tutorial, you will
set the target 36 yards from the muzzle of your weapon and leave the rear
sight elevation knob at 8/3 or 6/3. A range finder with a selector for
yards/meters makes this helpful.
rls303: Thanks again & also for the link for targets...Take care
BL Ranch: Thanks for the tip on the tag. I got it updated. I haven't watched Steve's
video, but I can tell you that's not a good way to establish a good BZO.
There's too much room for error when using the 0-200 large site.
semiautoriflelover1: Good job with the video, if you put "how to zero your AR15/M4 platform" you
will get more videos. Steve from safearmsreview is telling people to zero
with large aperture screwing up all the new shooters.
BL Ranch: Absolutely. Just pick a point on your rear sight and make all your
adjustments from the front sight and you will be in good shape.
BL Ranch: Actually a full regular step is approximately 3 feet. So 12 steps for the
36 yard would be what you are shooting for. It will be close enough to make
the rifle accurate. This might be a good follow up video idea. So if you're
out somewhere and your range finder goes down you can still get a decent
semiautoriflelover1: Why would you need to count the clicks with the A2 sights? A2 sights have
line in center, it was A1 sights you counted clicks.
BL Ranch: Something that may help with grouping is front sight focus. When you get
your natural point of aim and good body position, try making the front
sight post clear as you sight in on the target. This will cause the target
to become blurry, which would seem counter-intuitive but really helps in
keeping the groups tighter.
MR-FLIP: great info thank you i subed you for all your help...i have one last noob
question 75 foot steps is 25yrds am i correct.. my target finder broke so
iam trying my hardest to get the 25yrds to the T
BL Ranch: Yes. That was the 36 Yard BZO.
BL Ranch: I use either a 5.56 round or my Leatherman. I ordered a sight tool online
and it's not very good.
BL Ranch: Ha. That would be pretty impressive if that ever happened. I need to get
some new videos up. I'm thinking I'll do one with my new Remington 700.
I've been having a lot of fun with that thing.
Hayseed1776: How do you feel about the Burris 6.5x20x50mm would that be a good scope for
3-500 yards ? thanks again..
BL Ranch: I see what you are saying here with respect to that conversion. But what
this is showing is the 36 yard / 300 yard or 25 meter / 300 meter system of
zeroing irrespective of 27 yards equaling 25 meters. The ballistics show
that at 36 yards, the bullet's point of impact is the same as 300 yards.
The same is shown for 25 meters and 300 meters respectively. It's not an
exact science but for a combat BZO, it's good enough for engaging targets
at those two ranges; one for standard and one for metric
PAYBACK118: Thanks for your video and time. My sights (Magpul MBUS GEN2's) do not have
these 8/3 markings. Is there a way I could still use this method?
BL Ranch: The 6/3 sight is the same thing as far as this technique is concerned. When
you establish your BZO be it for the 300 yard or 300 meter method, you will
want to make all of your elevation corrections from the front sight post
initially. Once your zero is established, then you can adjust accordingly
from your rear sight elevation knob. This zeroing method just serves as a
start point and allows you to rapidly engage targets in and around 300
yards / meters.
semiautoriflelover1: I see your point, I hated the A1 sight because it has so few clicks. Have
you ever tried the Lt Col Chuck Santose improved zero? Where you unscrew
the rear sight and give yourself 2 extra clicks so you can have 200 zero
setting? Marines use this many times or at least the ones I talked to.
BL Ranch: It's my pleasure. Glad this helped.
Brandon Little: well done video sir
BL Ranch: M4 BZO Targets are up. Check out the links above.
BL Ranch: The principle is fundamentally the same when you are sighting in an optic.
The click ratio will vary, but the concept remains the same. A nice
spotting scope along with your aimpoint should do the job nicely. As for
the ballistics, if you are shooting the same or close to the same platform,
you could probably do the abbreviated short range technique.
TennGunLover: ok i have a question, i'm using a Matech rear sight (came standard on my
colt 6920) the elevation on the sight reads 200m, 300m, 400m, 450m, 500m,
550m, 600m. I dont have a 8/3 +1. Would you suggest using the 300m setting
and doing the 25m zero technique or setting it at 200m or another range?
rkrzbk: Thats what I do. I bring 3 targets. After two 3-round groups I tape a new
target over the previous one (I shoot through cardboard as well. I made a
target out of thick paint mixers and duct tape ; ). That way, I can track
my progress easier.
MR-FLIP: do you have to start off at mechanical zero.. here is my issue today i went
out and used the zero target how ever i delt with rely bad wind so i gave
up and came home i did make a few adjustment to sights..now can i get back
out when its not windy and continue to zero in or do i have to go back to
mechanical zero?? great vid you got a sub
worddunlap: Today's ammo prices caused me to use a laser to get the basic sighting,
then it took 3 rounds to check it, slight adjustment to elevation and three
more to check again. It's dead on and any missed targets are due to my own
errors. I used to know my settings on an M-16, we were told we could pick
up any M-16 and use those settings in an emergency. Civilian life has so
many options I doubt it would work.
BL Ranch: I don't think it matters much where the scope sits. When you adjust a scope
or sights for that matter, you are adjusting the sighting system to the
ballistics of that round. One thing you might consider is getting flip iron
sights which will allow you to mount the scope to the flat-top. I like my
scope as close to the receiver just so it's not banging into things. But
the actual distance from the barrel doesn't make a difference.
Rodrigo Chagas: Excellent Tutorial!
Hayseed1776: ok so I have a new question since I got my new scope I cant see my front
site I have my scope mounted on a Burris PEPR mount ,that mount is on top
of my tactical carry handle,now should I get a small riser to go between
actual top of carry handle and the Burris mount,that should get me up high
enough so I can use my iron site again,but the scope will be about 2 inches
above the barrel ,is that to high ?its either that or mount the Burris
mount right on top of the ar and take off the carry handle
