| I just put together a 9mm RRA with a MI rear and gas block flip up front sight. I'm new to this type of sight system and shooting low with not enough adjustment available. Centering the front sight post in the rear aperature, with the front post bottomed out of adjustment, I'm still low. What's next? Shortening the front post? Thanks, Lefty. |

What is your rear sight set at? If it's your point-of-impact that's still low, try cranking your rear sight up a bit. A 9mm doesn't shoot very far... definitely shouldn't wind-out an AR15 sight ETA: My bad, your rear MI sight isn't elevation adjustable. That could be a problem. |

I need some ballistics/trajectory/trigonometry help here. If it shoots 5 inches low with a center hold not a 6 o'clock at 25 yards with the front post bottomed out.........how much would one shorten the post to be around the center of adjustment at 75 yards? How's that for a question? (For seriously smart people only). |
