100 and 50/200 Meter Zero with A2/Detachable Carry Handles-RIBZ (Revised Improved Battlesight Zero)

[@davidstevens6117]

Excellent video and easy to understand. One thing - when you go either 3 below the zero for an A2 or 6 below for a removable carry handle, you really need only to go one more click down on either to avoid the sight bottoming out or getting a buildup of crud underneath the rear sight tower.

[@8mmmauserman]

True

[@AckzaTV]

I 3d printed this same thing 7 walls 50% triangluar infill banbulab, works so well. Even has rear sights module and all. U use a few metal nuts and springs. Its all on printables and even makerwofld

[@slavmuttgunslinger3012]

Just did this to my new detch carry handle on a 16inch dissipator with A1 furniture. I thought maybe Id stop at 6 clicks since id only ever use 50/200 but you sound like you did your research. Sadly dont have a 300yd range at the moment but I can do 50 on my land all day

[@8mmmauserman]

I have a range that has 100, 200, and 600. I still need to go out to it though.

[@tevetanders9729]

Back in the day.We used the large Appiture for night shooting with tracers or automatic fire with tracers.We loaded one tracer for every 3 rounds.It best used in the prone position to scan you firing scetor.Then flip to the small when your ingaged.Thats what we did.Some body may used for something different. That what this old man did.

[@charlesludwig9173]

Here’s a better idea, abandon the Military BDC function and set the sight for a 100 yard zero from rear sight about 6 clicks up. Then from a ballistics table for the sort of ammo used the sight wheel can be marked at 200, 300, 500, and 600 yard come-up’s. This gets a custom bullet drop compensation function across the whole spectrum of distances with less divergence between point of aim and point of impact at points of aim between distance markers. BTW, this is the means that all US Service Rifle Competitors zero their AR’s because it gets more accurate results at all distances.

[@8mmmauserman]

Definitely possible using this method too. I like a 50/200 for it’s versatility, but the 100 meter zero is equally possible. I’m assuming you’re talking about the detachable carry handle here?

[@charlesludwig9173]

@@8mmmauserman This concept works on A2 or detachable carry handle sight mounted to an M4 or A4. Just set out a target big enough at 100 yards to be able to recognize a consistent sight picture. Then, with elevation wheel turned 2 to 6 clicks up from bottom, sight-in, adjusting front sight post as needed for point of aim and point of impact to intersect. Next, using a ballistics app note the 200, 300, 500, and 600 come-ups in MOA from 100 yards and mark elevation wheel with nail polish at each increment corresponding to a come-up distance. You might color code or just memorize. I shoot Mk262 @ 2750 fps from A4, so clicks @ half MOA value from bottom as follows: 4, 7, 12, 28, and 38. Also, with the sight at 4 (100 yards) shooting at 50 yards bullet is only about .62 inches low.

[@8mmmauserman]

@@charlesludwig9173 I see what you're saying. Thank you.

[@charlesludwig9173]

@@8mmmauserman BTW, on A4 I have only one half minute left when 100 yard zero is at rear sight setting 4 clicks up from bottom. Also, maybe unrealistic for most, but, on my other Rifle with A2 upper, I can shoot at 1000 yards with rear sight set for 600 and front sight turned from original position 3 revs down. At the Long Range setting I can still get a great number of clicks if needed for exacting zero so I prefer A2 to A4 for long range.My A2 sight is also modified to a.25 MOA click value. One more thing, I have a mil spec detachable carry handle sight and unlike the commercial model with 39 clicks, the mil spec one only has a 32 click range. So no means to set beyond a 100 to 500 yard zero with some play for less than or greater than 100-500 yard zeroing.

[@JohnnyBallGame100]

Thanks

[@TheREALLibertyOrDeath]

50/200 zero makes me happy 🤠

[@8mmmauserman]

Same. It’s also how I do Red Dots

[@sbreheny]

I do find this interesting, but I am not clear on the benefit. Isn't the 5.56mm round pretty flat-shooting so that zeroing at 300 meters and keeping that sight setting will still get you within a couple of inches of the aimpoint? If you are going to worry about 2 or 3 inches, then you have to worry about height over bore as well, which inherently would require changing sight setting even for the difference between 50m and 100m.

[@8mmmauserman]

Great question, and here’s the simple answer, there are different battle rifle zeroes that people like. Personally, I really like a 50/200 yard zero. This is what I use for an optic like a red dot. I can achieve that with a carry handle by doing this. Also, some people may be trying to hit small targets at 100 yards/meters as that’s a common shooting range size. They may want to be able to adjust their sight accordingly. It’s not for everyone though

[@sbreheny]

@@8mmmauserman To make sure I understand, when you say "50/200 yard zero" are you talking about a trajectory where the bullet meets the "aiming line" twice, once at 50 yards, while climbing due to the barrel's slight upward angle, then then again at 200 yards, coming down?

[@8mmmauserman]

Yes. Most commonly, people set up Carry Handles at a 25/300, but I like a 50/200 because it allows there to be a slightly more precise impact point within those ranges. Ultimately it comes down to practicing with whatever it is set to, and using it well.

[@UrbanDefenseSystems]

Just to add, the main benefit of the RIBZ is the ability to allow you to shoot at very close and very long distances with a simple twist of the drum, all while being able to keep your general purpose 50/200 yard zero. The different zeroes that come in an all encompassing package with the RIBZ method, allows you to be dead on at pretty much any typical distance you'd find in a range. Think about how ranges are spaced out. 25 yard is common for indoor ranges. And outdoor ranges typically start at 50 yards, definitely have an 100 yard line, and if the range has 300 yards/meters or more... the RIBZ method really shines because it allows you to keep the working corresponding numbers on your drum that will allow you to shoot out to 600 meters. Most people who forego using the drum adjustments properly, are capped at whatever their zero is, which is typically either an 100 yard, 36/300 yard, or 50/200 yard zero. Not so with the RIBZ which will allow you to go out to 400, 500, and 600 meters.

[@FirstmaninRome]

ok, I find this stuff pretty hard to follow, if I had it in book form I'd be better off, I have a detachable carry handle, unfired, so it would work the same, different number of clicks?

[@8mmmauserman]

Yes, it’s the same style, but adjust it double the clicks that I do it in this video for the fixed carry handle.

[@adamjensen8775]

How do you zero with a carbine length sight radius? The RIBZ data I’ve seen is for rifle length sight radius

[@8mmmauserman]

I did mine in this video on a carbine and it lined up at 25, 50, and 100. Haven’t gotten to take it out further yet. The shorter sight radius and lower velocity could balance eachother out.

[@charlesmontrose]

how do you re zero the bottom two piece drum so you have a starting point i have an a2 detach handle if someone before you played with the settings already

[@8mmmauserman]

Good question. do the same process to adjust it, but you want to set it up so that it bottoms out at the 3/8 or 3/6 setting depending on the handle.

[@armenianesh818]

I had a quick question regarding zeroing with the RIBZ system. If I implement the RIBZ system does that negate the use of the "z" position in order to zero the rifle at 25m? In other words after I've made the RIBZ modification I just need to put it in the 6/3 position and zero at 25m and completely bypass zeroing on "z" at 25m? Or would I need to zero at 36m with the 6/3? You'll have to forgive me, my understanding of AR zeroes is dogshit.

[@8mmmauserman]

This will mean that when you do the zero the standard way, (on "z" at 36m I believe) when you dial it back, you will be on at 50/200 and 100 meters.

[@8mmmauserman]

[@sacredgarden1683]

thanks man, last question. If you zero for the 50/200 yard, does that mean the 300, 400,500, and 600 compensation will be off? still a little confused with everyones videos/explanation. i have a 10.5" that i only plan on shooting 200 yards max anyways. thanks!@@8mmmauserman

[@8mmmauserman]

@@sacredgarden1683 I don't think so, but one other issue: BDCs are made for a specific barrel length, and I'm not sure how it will match up on a 10.5...

[@sacredgarden1683]

i just want to say thanks again. spent 4 hours on youtube yesterday and yours is the best explanation. 1. when you sight in for the 25/300 after making the initial adjustment, you use the small sight apature right? 2. then when you make the second adjustment to bring it to 50/200 after its zeroed at 25/300, do you shoot with the small sight or larger sight when using the 50/200 zero? 3. a different channel said the big sight is 2.5MOA under the small sight true zero which is still kinda confusing.@@8mmmauserman

[@8mmmauserman]

@@sacredgarden1683 I'm glad to help. 1. Yes 2. Smaller 3. I've heard that too, but haven't tested it. I can;t give a definite answer, but I've heard both ways. Close range (within 100 yards shooting man sized targets) I think they're close enough it doesn't matter. I would like to test it myself to get definite answers.

[@gsueng05]

With the adjustable handle do you still zero on the 'Z' setting with this modification at 300?

[@8mmmauserman]

I THINK so, but I haven’t used the detachable enough to be certain.

[@Allenmar73]

No, the "Z" setting is only used for 20" barrel to zero the army way using a 25/300 battle zero and the M855 round.

[@salpanahi]

So a few questions for the detachable Carry handle: 1. After this method, can you re-zero it at 50 yards at 4 clicks or 6 clicks at 100m rather than rezeroing at 300m at the 6/3 mark? Wouldn't that be better since you can see better at closer? 2. Do you keep the aperture at the small for any distance after rezeroing, essentially not utilizing the big (0-2) aperture? 4. Do your 400m and 500m marks still stay true after RIBZ? 5. Do you loose the 600m after RIBZ since you went -8 clicks on the dial?

[@8mmmauserman]

1. yes, but should confirm at longer ranges if possible 2. yes, but can still use the large for close work (I use mine 2 eyes open target focused like a red dot) 4. Yes 5. Sometimes. It depends on the carry handle

[@salpanahi]

@8mmmauserman thank you good sir!

[@eleazarsoto9437]

I haven’t sighted mine yet. Do I have to sight it in first at the 6/3 mark and then move it -4 or can I go straight to -4 settings and sight it in for 50meters? Just asking since you said you would have to reajuste your sight for a ribz.

[@8mmmauserman]

You can sight it in after.

[@بهلولمولىالسجين]

Good❤

[@sidneywhite749]

Still confused. I just bought a SW ar15 and added a carry handle for nostalgia. I have never shot it. Do I bottom the front sight post first? There is no outdoor range near. Can the process be done at an indoor range. If so I guess I need a sandbag? Can you detail the range process ?

[@8mmmauserman]

You’d just do this process, and then zero how you typically zero a detachable carry handle. Thats something you can find details on in another video

[@Allenmar73]

Good explanation. I read when doing this mod to the 6/3 detachable going -8 set up that you lose the 600M. Have you found that to be true?

[@8mmmauserman]

Yes. Mine doesn't go too much past 500M

[@charlesludwig9173]

You do loose it. And, thinking about it you are loosing a more valuable feature than that gained at short range. In fact all a shooter need do at short range is hold low if a more exacting center of mass hit is needed. Thing is unless the shooter is a Master Class Service Rifle Competitor shooting a match conditioned rifle loaded with match grade ammo aiming low at precise need will not get a precise result so it’s all moot, meaning, for best results go with the /5/300 zero.

[@andrewjohnson6907]

You don't need -8. Lower the bottom ring 6 clicks. A 6/3-4 is 50/200 and 6/3-6 is 100. All the others are the same. I've checked mine at 50, 100, 200 and it totally works.

36 yards and a 20” barrel will always be my zero.

[@8mmmauserman]

Glad it works for you. My A1 is zeroed at 300 yards, but I’m a big fan of the 50/200.

[@Allenmar73]

How does your 36 yard work at distances compared to the 50/200 or 25/300? How did you set up your carry handle sight?

[@socaljarhead7670]

There’s no holding or doping the sight for elevation out to 300 yards. It’s made so that you own anybody who gets within 300 yards of you without having to do a whole lot of thinking. Set elevation during zero with the front sight post after you flush it out flat with the actual sight housing. Set the rear sight at 8/3 (6/3 for detachable carry handle) then come up I think 4 clicks, then zero for windage . Always use the small aperture, the big one is for night or with a gas mask.

[@UrbanDefenseSystems]

@@socaljarhead7670 Yeah there's no denying that the 36/300 yard is the most practical zero if you want a set it and forget it option, anyone who's been in combat knows the KISS approach to a combat rifle is very valuable. That being said, for an AR that sees all of it's days in a range, and MIGHT be used to defend an apartment with at best a 10 yard line of sight, the RIBZ is incredibly fun to use to reach out to 600 meters (if you have access to a range with those distances).

[@ThaBlkDahliaMerdersU]

what's your barrel length?

[@8mmmauserman]

This one is a 16.

[@Hector_Malot]

It is the vertical movement of the rear sight which modifies the distance at impact. Once the sight is down, it won't go any lower, and you can turn the lower wheel as much as you want, it won't change anything since the peephole is attached to the sight block. This manipulation brings absolutely nothing because this type of imprecise sight is not designed to shoot below 300 m.

[@8mmmauserman]

I say this respectfully, but you don't know what you're talking about. You can't turn the sight once it's bottomed out, and this modification allows you to set elevation below the 300 mark. I also recommend you watch the 9-Hole-Reviews video on the M16a2 to see how precise this sight can be.

[@armedfarm3429]

My 2 peeps have a different POI, my big one shoots lower than my small peep which rotates to a different higher POI. You can figure all this in also. I can use the bigger peep for 25-150yds. The smaller one will raise the poi around 6" on my detachable for long range. So, IOW another round of different settings. If the SHTF I want to know what center hold will smack & at what range. Keep it written down & in the pistol grip until it's 2nd nature. 25-300 will work but I'm a bit more precise.@@8mmmauserman
