A rifle that carries a magnified scope is excellent at distance and awkward up close. The view is narrow, and at low distances it can take time to find the target. A red dot has the opposite trade-off, and it relies on a battery. Either way, one optic gives one sight picture.
Offset irons are a simple way to add a second one. Ozark Armament sells 45 degree offset iron sights. The pair, one sight for the front of the rifle and one for the rear, clamps to a Picatinny rail and leans out at an angle next to the optic. The optic stays where it is. To use the irons, the shooter rolls the rifle slightly until the front and rear line up, then rolls back to the optic.
Amazon lists them under a title that includes "folding" and "flip up", so they can lie down when not wanted.
Before choosing an offset set, check three things:
open rail next to the optic, near both ends of the rifle
the optic mount does not block the angled line of sight
the side chosen suits the shoulder the rifle is fired from
The listing has photos and buyer questions that help confirm fit with a particular rifle.
