RIBZ - - Revised Improved Battlesight Zero (Page 11 of 11)
|
it didn't need any extra
so I just kept it at -6 now, does anyone have a good idea about how to mark these on my rifle? the clicks for a 20 inch a2 style detachable carry handle 25 meters: “Z” setting 50 yards/200 meters “battle zero”: “6/3 -4” 50 yards: “6/3 -4” 100 yards: “6/3 -6” 150 yards: “6/3 -6” 200 meters: “6/3 -4” 300 meters: “6/3” (or “8/3″ with fixed carry handle, 20” barrel rifles) 400 meters: “4” 500 meters: “5” 600 meters: “6/3” I am not using a football wristband. Looking for other suggestions to just have them written on something and then applied to rifle, or written straight on the rifle (once I get it zeroed in of course) I also plan to put the info more succinctly if that matters 25-z 50/200 bzo-4 100/150-6 300-6/3 400=4 500=5 600-6/3 |

I like getting the most accurate data as I can, for my MV and BC, plugging it into a Ballistic Calculator for different zero ranges, pick the one I like, zero, then confirm at varying distances if possible. |

| has anyone put a laminated dope card for various ribz 8/3, 6/3 for a2 and detachable carry handle on the non roll mark side of their magwell? if so, how did you stick it on there? |

the more and more I shoot
the more I like the ribz I am not the best at 100 yards yet-- my skills are improving---my eyes are not but with ribz----I can dial in minute of man if I use a blitzkrieg front sight triangle considering I in all likelihood won't engage a real target in hd situation shtf under 100 yards---a battle sight zero like ribz is just so KISS, I can't help to fall in love with it |

Where'd the PICs in OP go??! BTW, dont know if anyones seen this yet, but its a very thorough writeup on army/marine/ibz/ribz zero schemes, their pros and cons and ballistic data. Its helped me understand the ar15s sights better https://savannaharsenal.com/2017/04/08/how-to-zero-ar-15-a2-type-sights/ |

I'm confused by the 8/3 +3 25yd poa=poi If you're zeroed with the RIBZ and all sight schemes are intact (roughly), shouldn't the 8/3 setting give you a 25yd poa=ppi because near zero for 300yds/m is 25ish yds? Thats per the RIBZ info here. BTW if you haven't read this page thoroughly you're missing out. https://savannaharsenal.com/2017/04/08/how-to-zero-ar-15-a2-type-sights/ +3 seems like a lot if the 300 near zero is 25ish yds. |

No, it isn't. Thats per the RIBZ info here. No, it isn't. Here are the actual trajectories that I posted in the original post of this thread. 25 yard zero  25 meter zero  300 meter zero  |

@Molon Glad the pics are back up and that this thread is still here because I’m about to pull the trigger on a 16” H & R government model upper, which has A2 sights. Now, about that book you’re gonna put out…

Great info. I recently bought an AR15A4 with removable handle. The manual says to move the rear elevation to 6/3 and back two clicks. But when I move the drum all the way down it bottoms out on the little “z”. My question is how to get the rear sight to the factory settings so I can try your system? |

If you want it to bottom out on 6/3, set it there, then thru the top loosen the little screw in the drum, turn the bottom half of the drum down, and tighten the little screw. |
