Description
The Athlon Scope Heras SPR is a 4-20x riflescope with a 50mm objective. The reticle is in the second focal plane.
A 20x top end is intended for precision at distance. High magnification narrows the field of view, shows mirage more readily and makes the picture more sensitive to how steady the rifle is held.
Second focal plane: the reticle stays the same visual size at every magnification, which keeps it easy to see at low power. Its subtensions are only correct at one magnification, usually the maximum, so holds taken at another power have to be adjusted.
The 50mm objective sets how much light the scope can gather and how tall the rings need to be to clear the bell.
