You need to copy and paste the links, the forum does not recognize the addresses as links. It's really worth your time. Some of you may be familiar with this method. The rest of you need to check this out. http://groups.msn.com/TheMarylandAR15ShootersSite/improvedbattlesightzero.msnw Then look at the trajectory information. http://groups.msn.com/TheMarylandAR15ShootersSite/zerotrajectories.msnw This seems like a better way of doing things. From 25 to 250 meters the bullet does not raise or drop more than a few inches, Vs. about 10 inches with the standard 25 yard 300 yard Zero. Do some reading, What do you think? Feedback would be appreciated. |

Yes, it does, but you have to use UBB code. Neatest trick is imbedding the link as such: [url=http://groups.msn.com/TheMarylandAR15ShootersSite/improvedbattlesightzero.msnw][b]An Improved Battlesight Zero for the M4 Carbine and M16A2 Rifle[/b][/url] [url=http://groups.msn.com/TheMarylandAR15ShootersSite/zerotrajectories.msnw][b]Zero Trajectories[/b][/url] |

The Santose Improved Zero is the best thing since Wonder Bread. It makes SO MUCH more sense than the military zero. Don't hesitate. I've got all my guns setup this way, and I set up everyone that wants it that comes to our shoots. You can do the same thing for optics, but you need to recalculate for the Height Over Bore. For example, a carryhandle mounted compact ACOG works out great with a 75 yard zero. |
| Thanks for getting the links to work! I'd almost like to have the iron sites set this new way but the scope for a bit longer range. What amazes me is that all you have to do to shoot long range is turn the rear site wheel. I also heard the if you want to shoot at 25 meters with this setup you can click to 4 on the rear site. Do you know about this? I had one guy tell me he went to 8/3-3 instead of -2 to shoot better at 100 meters. I like to aim dead on. So this should allow me to aim dead on to about 250 meters I was told. How does it really operate at a distance. This would be my concern. I wonder which manufacturer will make a 2 or 1 notch on the rear sight first if ever? the "A5 stlye"[:D] |
| I just finished the rear sight mod, no all I need to do is adjust the front post. This is my question, The manual say to always adjust elevation with the front posts. I'm going to sight in at 50 yards or meters rather. Am I right in saying, once the front sight is on target then leave it alone. The rifle is zerod. Then if I need to change it for long range shooting the rear wheel is where I make that change. Right? |

I set my sights up with this improved zero method, and the rifle is right on out to 100 yards (haven't tried anything farther) with the small aparture. I'm a little confused on using the large aparture though. The method says you can switch to the large one and turn the elevation wheel back to 8/3 and still have the POI the same. Has anybody gotten this to work out? Yesterday I tried the large aparture and 8/3 setting. I couldn't find any holes at 50 yards. Any idea what I did wrong? Thanks Scott |

The large/small aiming holes are inline. Which means that they do not compensate for the side movement of the aperture leaf on the windage screw. I think A1 leafs had this windage compensation, but both the holes were the same sizeand had some elevation put into them also, and thus instead of a big hole/close range and a small hole/long range like on the at A2 aperture. You had a small hole/close range and a small hole/long range. I think that someone said that windage moved about 3-4 inches on an A2@100 yards. It would be considerable worse on a carbine too. Kind of a bad point in the sighting system. I was thinking about getting an A1 aperture and drilling the close range hold out. Don't know how that would work though. Be worth the money to find out though, they are only like $7 a piece. |

Thats right aka_Krill. 8/3 -3 clicks is a 100 meter zero,8/3 -2 clicks is a 200 meter zero,8/3 is your 300 meter zero etc. For the 300 meter battle sight set the sight to 8/3 and flip the 0-2 large aperture up for close in. To sight in at 25 meters set the sight to 8/3 +1 click using the small aperture and zero.Fine tune at 100 etc. if needed. When using the 8/3 setting and small aperture 300 meter battle sight your groups will be high on any target below 250 meters.This is why the IBZ works so well in most situations for folks. But most of my shooting is done at 100,200,300 meters so the 8/3 -3 setting works best for me. I zero at 25 meters and fine tune at 100 etc. With this setting I can pretty much shoot and hit point of aim from 25 meters on up the scale. Basically it just gives you more room for fine tuning. When hunting I just set the sight to 8/3 -3 since that pretty much covers most shots I will take on a coyote in the woods. Both the IBZ and the Marine Corp 25 meter zero are good and depends on what you want. Raymond |

I recently attended the Gunsite carbine class and we zeroed at 50 yards. They didn't get into loosening the allen screw on the A2 sights. They advised just using this sight setting for any practical range. We shot from 3 yards out to 400 yards and I was very happy with the result. At very close ranges I just held a little high and at the more extreme ranges I also held a little high. We didn't shoot at bullseye targets, we shot at silhouette targets for both head shots and COM shots. They wanted to see tight groups in the vitals. At close range I held in about what would be the center of the forehead on a head shot and just a little above the nipple line for a body shot. At 400 yards I held with the bottom of my dot sight about half way up the head on a steel pepper popper. I would like to know more about this variation with the dot sight being higher above the bore. |

Quoted: ...Marine Corp 25 meter zero are good and depends on what you want. Raymond The USMC has abonded the 25M zero as the 8/3+1 does NOT produce a 300M zero (its about 10" HIGH at 300M). They have are now setting the dial to 8/3 and zeroing at 36 yards. This produces the proper 300M zero and calibrates the dial. Not as flat as the 50y/200m zero. |
