[QUOTE="Ballistic64, post: 100529, member: 3401"] [ QUOTE ] Centre Punch, increasing sight radius between front sight (or fore sight) and rear sight (or back sight) doesn't help aiming. The shooter sees the same angular error between line of sight and line to target for a given angular displacement regardless of the distance between the two sights. Increasing sight radius reduces the amount of impact change per click on the back sight and makes it easier to see for eyes that have degraded somewhat; that's all. OK, now that I've said that, dozens, hundreds or thousands of folks will say I'm wrong. But if each one of these naysayers looks into an aperture rear sight through twelve front aperture sights all aligned in a straight line and 3 inches apart (the furthest one being 36 inches in front of the rear sight; typical of Palma rifles), they will notice that for a given amount of misalignment with the downrange target, each one of those twelve front sights have the same angular error relative to the target's bullseye and they'll all stay aligned with each other. [/ QUOTE ] This is not necessarily true.While the front sights do have the same angular error,the front sight is a further distance from the rear aperture than the one closest to it and is more accurately brought into the center of the aperture.This is nothing new,it is the same reason silouette pistol shooters prefer longer barrels and has nothing to do with aging eyes.A very short sight radius (front sight to rear sight) is much easier for aging eyes to bring into alignment with a given target but is hardly as accurate.
