Don't you mean "apparent" rise at 25 yards? Since the irons are nearly 1/2" above bore axis, you do have a bit of parallax to deal with. From my tiny bit of education, gravity takes effect immediately ... in this case, when the bullet leaves the barrel.barracudadave67 wrote:If a rifle, or carbine is shooting 4-8 inches high with the stock sights, the first thing to do is replace the front sight with a much taller front sight. This will bring the POI down. When I replaced my sights I removed the fronts and measured the height of them, and ordered accordingly, some had to be higher, some lower.
All 4 of my R92s have Marbles full buckhorn rear sights, and either Marbles 1/16th front beads, or Williams firesights. My 16in .45colt shoots excellent groups at 50 yrds, and opens up just a little at 100yrds.
I did not shoot my 92s with the stock sights as I did not like them. they were not fine enough for me. I have old eyes at 75yrs.
Something is not right with rifle, or you are using the wrong front sights, that are too short. A rifle shot at 25-30 yrds still has the projectile rising at that distance, did you shoot it at longer ranges,??. Maybe you know all this.

Not nitpicking ... just clarifying - or useless blathering, which ever might be the case.
