First things first, new to the site and all I can say is AWESOME! Everybody seems knowledgable and very helpful. I just purchased my first AR15 which is a RRA LAR-15 NM A4. This is a flat top with removable carry handle. The zeroing directions provided with the weapon as well as all the other zeroing directions I have found on the web refer to the 8/3 mark on the rear elevation. However there is no such mark on this style/model rear elevation, just dots. Some of the RIBZ directions talk about a hex nut to loosen when on the 8/3 mark. Guess what, no hex nut either. So what should I do without the 8/3 markings and no hex nut. I would like to zero at 50 yds, should I jjust set rear elevation to mechanical zero and go from there or does someone have better ideas/experience with this sight.

hmm, i have nothing to say to help, but i just ordered a RRA a2 detachable carry handle (gotta love their dealer pricing cuz of my $30 C&R license), i sure hope it has a traditional elevation dial and construction, 'cuz i plan on putting a RIBZ on it too...
does the nm rear have a hooded aperture? |

there is a difference in how you zero your national match . you should go to the competition forum and do some reading and go to the rock river industry forum there is some info there .
here is one thread |

The detach carry handle is marked 6/3, not 8/3. Follow the RIBZ, but you need to double up on the clicks (the detach has 1/4 minute adjustments vs. the fixed 1/2 minute clicks).
RIBZ If you go to the bottom of the post at the link, it mentions that you double up clicks for the detach handle. |

Set the FS, windage to mechanical zero and the elevation drum to zero. Then sight in at given range. Mark your sights and your done. Or just send it back |
| Thanks to all who lent there help. I returned to Camp Perry today and spoke with the RRA folks who are great help. Since I will be shooting it for match purposes I will need to perform a 100 yard zero, count clicks or mark dots etc and go from there. The sight on this weapon is intended for match shooting so it is set up a bit different. It seems all of you who replied were right with your suggestions in one form or another. Thanks again. |
