How do I adjust the rear sight on my Ruger auto. 22/45 MKIII ?
The rear sights on your Ruger pistol should be installed in a dovetail, to adjust the rear sight you drift the sight to the desired position. Secure the pistol in a vice ( wrap to prevent marring) use a brass punch and hammer to tap the sight base, it may be tight but once it breaks free it will move.

The rule for sight adjustment is to move your sights in the same direction you want to move your group. If you group is high and to the left, move your rear sight down and to the right.
The rear sight is used for windage adjustment and to change the zero range.
Handguns with drift-adjustable sights can only be adjusted for windage, or left/right shifting of the point-of-impact, because these sights tend not to have any means for adjusting elevation.
Fixed sights may be zeroed to certain loads, but once zeroed, that is it. A handgun with adjustable sights may be zeroed for one load and then re-zeroed for another. If you are really good at the game you may even tune the elevation setting for different ranges.
Shoot three arrows, and then loosen the screw that lets you move the sight housing left and right. Move the sight housing toward the group. Shoot three more arrows to check your adjustment, and move the housing again if necessary. Next, move your pin up or down until your group hits where you aimed.
Before you take your new AR-15 out for target practice or into the field to do some hunting, the first thing you will need to do is zero in the iron-sights. All rifles and upper halves with sights installed from the factory are bore sighted to 25 yards.
Sight alignment is the process of lining up rear and front sights. It is especially important in handgun shooting because of the shorter distance between sights. The sight picture is the image you see when the sights are aligned correctly with the target.
If the sights are not aligned correctly, then the sights should be adjusted to bring the line of sight to meet the point of impact. Theoretically, this can be done with a single shot—clamp the firearm into a vise, fire one shot, then adjust the sights so they are pointing at the hole in the target.
The Drift Sight was a bombsight developed by Harry Wimperis in 1916 for the Royal Naval Air Service (RNAS). It used a simple mechanical device to measure the wind speed from the air, and used that measurement to calculate the wind`s effects on the trajectory of the bombs.
Telescopic sights provide the most accurate aiming, which makes them popular for hunting.
Most fixed sights these days are semi-adjustable in that they are dove-tail mounted and can be drifted for windage but not for elevation. However, there are still many sights that are fixed, such as with small revolvers with a machined-groove for a rear sight, single-action replica revolvers, and with some pistols.
To aim, you center the target in the rear peep or aperture sight, and then bring the front sight into the center of the hole. An aperture sight lets you aim more accurately and is adjusted more easily than an open sight.
In daylight shooting applications, laser sights are as effective as iron sights. However, laser sighting is more effective than traditional iron sights in low-light scenarios.
Sniper rifles do not have iron sights. Some weapons that start with a optic sight (such as the Pentagun or the As Val`s long-range variant) will gain iron sights once the optic sight is removed, lowering their drawtime and increasing their capacity in close quarters.
“Mechanically zeroing the weapon is only necessary when the weapon zero is questionable, the weapon is newly assigned to the unit, or the weapon sights have been serviced.” Mechanical Zero is nothing more than putting the sights in their centermost setting.
: a rear sight for a firearm that has the graduations corresponding to the tangents of the angles of elevation and that is usually graduated to read in yards of range.
Like with long guns, pistols (and, in fact, all handguns) are compatible with two general categories of sights: iron sights and optical sights (or simply optics). Sights for handguns are not fundamentally different from sights for long guns, such as rifles or shotguns.
In order to achieve normal binocular vision, the eyes must see well, be aligned (i.e., look in the same direction), and be focused on the same object. To maintain alignment, the eyes must also move in a coordinated manner. Misalignment of the eyes is called strabismus (or squint).
Alignment is very important to keeping your documents and overall design pieces clear and cohesive. Without proper alignment, elements and your overall piece can appear disorganized and disarrayed. It is so important to understand how you can properly align elements so that everything appears cohesive.
What color is best for gun/fiber optic sights? Green/yellow is the spectrum that human eyes detect best in most settings, according to Trevor Young (director of sales at HiViz), and so it is the company`s most popular option.
A red dot is composed of a tilted spherical mirror that reflects the red LED. This mirror has a specific coating that only allows red light to pass through—hence the name “red dot” sight. This allows you to easily see where you are aiming against darker backgrounds, or in the woods where it`s green.
It really doesn`t matter whether you shoot with one eye open or both. Most shooting instructors will tell you that you should do what feels natural and gives you the best results. If you`ve started with one eye closed, it may be worth trying to learn how to shoot with both eyes open.
In terms of speed, the comparison between reflex sights and iron sights isn`t even close… Optics are much, much faster! This has been proven in both the military and especially, by civilian competition shooters. You see, in shooting competitions where speed is critically important…
Around a corner it is not the fastest way, as a straight line will propel you faster, since there are no interruptions, but drifting can be as fast as around a corner as driving around a corner in a traditional way.
