risers

[gnm]

What happens if the front sight riser is 2 mm taller than rear sight riser? Will it run out of elevation adjustment? Any other potential problems?

Anschutz 1913 usually shooting at 50 feet and 25 yards and very occasionally at 50 yards

Risers: 44 mm front, 42 mm rear

Thank you.

That depends on the rearsight, foresight, and sight radius I expect. But, yes, raising the foresight more than the rearsight will require more elevation adjustment than if the raisers are of equal height*. However, if you have a long extension tube, then a taller front raiser may compensate; some tubes recommend a front raiser/extra raiser.

*A taller rear raiser will compensate for a taller foresight, or just free up elevation. I run approx 12mm under a 22mm tunnel (on a 10in Uptatuner) but 15mm at the back, with a 40in sight radius.

Interesting. Thank you.

I decided not to get this combination and instead buy equal height risers.
