I like NECGs but my favorite irons for rifles are Trijicon 3 dot sights. Trijicon part number RE05Y.

They are marketed as sights for the 870 slug guns. They install in the basic Remington rifle/slug gun sights (i.e. the generic ones that used to come on 700's and still come on 870 slug barrels).

The trijicon sights have a big bright white dot up front and tritium vial. Huge leap over any sort of brass bead or sourdough setup. Like night sights for your pistol except on a rifle. Especially in dim light--last half hour of dusk when you can see animals but maybe not your sights--these are a game changer.

About $110 on Amazon. But you do have to use the generic Remington 700 type irons. Or some other dovetail front.

That said, the NECGs are prettier and I have them on a few guns I didn't want to ugly up.
