What's your 223/5.56 "zero'd" for and why?

[fanchisimo]

I've never heard of MPBR, but it uses the same reasoning I do for my 50/200 yd zero.

 

[Arizona_Mike]

It depends on my optic. For My EOTech I use the center dot at 50/200 and that gives me the lower dot at 500 and the bottom of the ring at 7 yards.

For my Burris LTS, I use the center of the center dot at 100, the bottom of the center dot at 200, 2nd dot at 300, 3rd dot at 400, and so on until the lowest dot at 600.

Iron sights: 50/200 IBZ.

Here is a good read on the logic of using MPBR to zero your rifle.

I use a 25 yard zero for my 16" AR with Aimpoint H1, and a 100 yard zero for the stainless 20" free floated bull barrel AR with a 24 power scope which usually sits at 10x.

The 16" will easily hit within an inch or two of POA at 100, and the 20" is good at 200 too. With the 55 grain bullets I'm usually shooting, that's plenty. The 16" has been used for carbine courses, and the only correction I have to account for at CQ distance is the height difference between the sight plane and the barrel (about 2.5"), which only matters for REALLY precise shots. Hitting silhouettes in the vital zone does not require compensation.

50 METERS. A2 irons, 55gr WWB. Aimpoint H1 mini red dot is matched to that. I can transition from irons to red dot with the same point of aim.

This matches the iron sights adjustment out to 600 meters.

 

[AABEN]

I set all of my long guns from 223 up to 30.06 at 150 yards. That way you are a little high at 100 Yd and a little low at 200 Yd it works good for me.

 

[Cosmoline]

I did RIBZ with my A2 sight and have adjusted the A1 sight to 100 meters.

RC Model;
Thanks thats what makes perfect sense and what I have been doing at the range for years.
I hope everyone takes a minute and reads that Link.

 

[Sour Kraut]

RC: thanks for the info and the links. It makes so much sense and your perspective is exactly why I was looking for. I'm off to the range next week armed with great intel! Sighting in my AR for the first time.....Irons and Aimpoint Pro.

 

[Ar180shooter]

i use 50/200 for red dot sites.
ACOGS and such with special reticles, depends on the reticle
i use 100 yard zero for scopes with target turrets

This. I do exactly this.

 

[tactikel]

+3, 50 yards reddot, and 100 yards for scope with ballistic reticle.

 

[carbine85]

Iron sights - 2" above zero = O at 200
I use O at 100 with my scoped rifle and it has a bullet drop compensator built in for 200, 300 and so on.

 

[mf-dif]

25 yards.

 

[Art Eatman]

I've sighted in many and many a sub-MOA rifle. What I've found is that dead-on at 25 yards can be two to three inches off at 100 yards. High doesn't hurt, but off to one side by two inches is a real bummer.

 

[WVRJ]

I go 2 inches high at 100,that makes it on at 225.I also use the turret to go beyond that setting when I'm poppin milk jugs full of water at 600.Sort of a mixed up method,but it works for me.

This!

A 25 yard zero isn't zeroed at all, if you truly want to hit something small a long ways away.

25 yards is only good to get on paper for a preliminary zero before moving on out to 100 or more to dial in the last few clicks for a true zero.

[Dr T]

2" high at 100 yards. It makes it a point blank shooter within the field limitation of the cartridge.

 

[wgaynor]

For my AR15, 100 yard iron sights and 25 yards laser. For my Remington 700, 2inches high at 100 yards and use mildots for anything past 300.

 

[wgaynor]

The real key is to stick to a specific projectile and practice with it at different distances to know your limitations.

 

[Sour Kraut]

I'm going to the range tomorrow to sight in my new rifle; irons and Aimpoint Pro. After mounting the Aimpoint (1/3 co-witness) the two are out of alignment windage wise. So obviously I have some work to do with one or both sight systems. I have access to 25, 50, and 100 yard targets. Should I start at 25 or 50 to start the process?

 

[s2brutus]

My various .223/5.56's (not just ARs) are zeroed for either 100 or 200, according to what I do with them.

The couple that are zeroed at 200 are ARs and that's because I shoot the occasional CMP "Modern Military Rifle" match with them.

The ones that are zeroed at 100 are "just because".

 

[C-grunt]

Travis Haely did a REALLY good video on AR zeroes. Doesn't go into opinion much, just shows the facts.

[allaroundhunter]

My competition AR is zeroed for 100 yards because the MTac on top of it has a BDC that is dead on out to 600 yards when zeroed at that distance.

My defensive AR wears an Eotech and is zeroed at 50 yards.

Start at 25 to make sure you are on paper. Get it close to zero there and then move to 50. Take a shot or 2 there and make sure you are still close to zero (within a couple inches) and then move to 100

you are right . sighting at 25 yds to me is like bore sighting. gets me on paper at 100-200 where you have to fine tune sometimes by a few inches
