Lyman and others offer folding leaf rear sights that can be used to fill the empty dovetail if desired. A hammer and a brass or hardwood drift pin is recommended for this chore. The hardest part of the whole operation is removing the original rear sight from its dovetail grove so that it does not interfere with the new receiver sight. Anyone, even I, can accomplish this minimal chore in a couple of minutes. The pre-angle eject Winchester Model 94 rifles were drilled and tapped for receiver sights, so all the user has to do is mount the sight base to the left side of the receiver, using the two provided screws, and slide the sight into the base. This feature allows the Lyman receiver sight to be used as a backup sight on scoped rifles fitted with a quick detachable scope mount, and it is often used in just this way on African "safari" rifles. The sight is mounted to its base by means of a quick release slide that allows removal of the sight and its return to the same point of aim when it is reattached. Like all Lyman receiver sights, the Model 66A incorporates 1/4 MOA click adjustments for windage and elevation and comes with two interchangeable (screw-in) aperture discs, one for target shooting and one for hunting. Thus it is that the specific model of Lyman receiver sight chosen for review is the 66A, mounted on a pre-angle eject Model 94 Winchester rifle. A receiver sight solves both of these problems and is far superior to the open sights supplied with the rifle. And a scope interferes with carrying them in one hand, grasped around the receiver, the most natural method. These are perhaps the best handling hunting rifles ever produced, but they are awkward to scope. One popular application is on pre-angle eject Model 94 Winchesters. Still, the aperture sight has its place in the scheme of things. Telescopic sights, which put the target and aiming mark in a single sighting plane, having become the preferred sighting system for most hunting purposes. The aperture sight is not as common on hunting rifles as it once was. The Model 90MJT is a target sight for most bolt action.

The Model 66 series is for the Browning/Winchester Model 1886, Marlin 39, Marlin 336, Marlin 1894 and Winchester pre-angle eject Model 94 lever action rifles, as well as shotguns with flat receivers. Lyman offers their Model 57 series receiver sight for the Remington 700, Savage 110, and Winchester Model 70 rifles. The rear aperture sight is still the standard aiming system for most military rifles around the world, which means that hundreds of thousands of individuals who have served in the military are familiar with its use as well, of course, as the thousands of civilian hunters who have used them since the late 19th Century. military adopted this more accurate type of sight before World War I and practically all major powers eventually adopted the aperture sight. The eye will automatically peep through the center of the aperture without conscious thought. Focus is required only for the front sight and target. The eye looks through the aperture, also sometimes called a peep or ghost ring (because it is blurry), making no attempt to focus on the rear sight. Then as now, the receiver sight offered a simpler and more accurate sight picture compared to standard open sights. I first used a Lyman receiver sight on a Model 94 Winchester about 40 years ago. Lyman has manufactured a wide range of precision aperture sights for as long as I can remember. Peep sights were, in fact, the original product on which the company was founded.

They are probably best known for their reloading supplies, reloading manual (in its 47th edition as I write these words) and their aperture sights. The Lyman Company has been around since 1878. Illustration courtesy of the Lyman Company
