As a rule, the factories put the cheapest, sorryest sights on a gun that they can get away with. If you have a top-eject LA rifle, then put a good aperture sight on the rear, and a good, visible sight up front. (I prefer the old-time Redfield Sourdough type front sight, if you can find one, or maybe one of these here new-fangled fiber-optic things). If your rifle has the capability of having a scope mounted " low-central-overbore" , then just zero the irons for emergency use, and put a small, light low-power scope (like a Leupold fixed-power 2.5X or 3X) on it in quick-detachable or swing-off rings, and use the scope as your primary sight. Avoid these so-called see-under abortions!!! They are weak, and make you have to put your face way too far up in the air above the stock comb to get the steadyness you need to shoot well!! BON CHANCE!!
