| If i move the front sight block over .125" how many inches off the center of the target will that make the impact point at 100 yrds? |

Ok, I'm not math literate so can someone check me on this? The Army AK-47 operators manual states, " Moving the front sight slide to the left, right, up or down 1mm, changes the strike of the bullet 26cm at 100 meters."
1mm = .0393 in 26cm = 10.236 in 100m = 109.361 yds So if I move it to: .1179" = 30.708" or 2.559' @ 109.361 yds .1179" = 15.354" or 1.279' @ 54.680 yds .1179" = 7.677" @ 27.34 yds My math skills suck, is what I came up with correct? If I move the front sight post almost .125" it will end up over 7.5" at 27.34 yds? I know i'll probably get slammed for this!!!!

How far are you wanting to move it? Where did you get the .1179" figure - 3mm? Why do you want to calculate at 3mm windage adjustment? I guess I'm not understanding what you want to do. 0.125" = 3.175mm. So, 3.175 times 26cm = 82.55cm = 32.5" at 100 meters. That would be 16.25" at 50 meters or 8.125" at 25 meters (27.34 yards). |

My front sight block is canted to the left (from the factory: CIA) and I wanted to convert the metric that was used in the US Army Operators guide to American Standard Measurement so I can take some of the guesswork out of sighting in the rifle at close to 25yds. The .1179 figure is 1mm or .0393" x 3 (this is as close to .125" as I can get without breaking it down further). I guess I could have used .0393 x 3 + .0098 = .1277" but I didn't think of it at the time that I posted this, and plus, I will be eyeballing this thing. I want to move the whole sight block over to the right and then tweak it by moving the sight post. I was trying to figure out how moving the sight block .125" to the right would affect where the point of impact would be at roughly 25yds, 50yds & 100yds. |
