How do aperture sights work




















Photo by Rab Cummings What if I told you of a rifle aiming system that was fast, rugged, and inexpensive? What if I told you of a rifle aiming system that was fast, rugged, and inexpensive? That was as effective on a rimfire as on a dangerous-game rifle? And, almost unbelievably, what if I told you it actually improves your vision? This super sight exists, though it has been nudged aside lately by red-dots, reflex sights, and low-mag riflescopes.

Before I extoll the virtues mentioned above, a little context: I grew up hating peep sights. My father was a peep-sight apostle, and he installed various Lyman and Williams receiver sights on every rifle our family owned. They were very much at home on the battery of lever guns he owned, but even on those Winchester. As our eyes age, it becomes increasingly difficult to shoot open sights, as our focus strays between target, front post, and rear notch.

They break, he says. He once sent me a. When it got to me, the scope was busted. No red dots. No holograms. No peep sights. Over the course of more than a century, PHs have found that the combination that works best for them is a big bead up front and a shallow rear V. The best material for the big bead is gold or ivory. The traditional open rear sight is a shallow V, and the good ones often have a vertical line of gold or silver inlaid in the steel that runs from the base up to the bottom of the V notch.

The really good ones have a gold triangle that does the same thing. In use, you put the bead on the notch, pull the trigger, and concentrate on not wetting yourself. The reason is that most PHs subject their rifles to a fantastic amount of abuse, some unavoidable and some not, and an unmovable rear sight is about the only thing that holds up.

These are a superb waste of money, as dangerous game is almost never shot from beyond yards, and usually much closer, and the useless little leaves have a habit of folding flat whenever they feel like it. An open rear sight is properly set to hit dead on at yards, or 50 yards, and then left strictly alone. This is why quick-detachable, or QD, mounts were invented.

Almost all of them clamp to a base or a rail via levers. There are a number of less-expensive rings designed for rails and for Weaver-style bases. They all work fine.

The thing to remember is that it pays to tighten the levers with a light touch.
