Smaller apertures refine depth of field for longer ranges and detail-rich targets, while larger apertures boost light transmission for quicker, instinctive aiming in bright conditions.

The protective case keeps all six apertures protected and ready, so you can switch setups on the fly without sacrificing accuracy or reliability.
