Does scope go bad?
Scope can be stored both unopened or opened for a period of 3 years. For best results, keep it in a cool dry area, away from heat or direct sunlight. Cap the bottle securely after opening to prevent the evaporation of water and alcohol, which may cause change in taste and/or effectiveness of the mouthwash .
Why do I see black when I look through a scope?
A Little Thing Called Eye Relief
Eye relief is the distance between the lens of your binoculars or scope to the tip of your eye. When viewing a scene through any lens with incorrect eye relief distance, the picture you see will be distorted, either with a fuzzy image or with a black ring around the field of view.

Why do scopes lose their zero?
Make sure the scope rings are properly tightened and there is no play in the scope to rings or rings to rail connections. This is the most likely problem when a scope won’t hold zero, either because the parts fit poorly, were never tightened, or the scope rings worked loose as the rifle was shot repeatedly.
What do the clicks on a scope mean?
Each time you move the turret, it clicks, and the lines below the numbers guide you. So, if your scope says it has the ¼ MOA adjustments, it means you need four quarters or four clicks to make 1 MOA. If it says ½ MOA adjustment, then you need two clicks to make 1 MOA.
What causes a rifle to be inaccurate?
Rifle barrels must have absolutely uniform dimensions (to the ten-thousandth of an inch) for the length of their bores in order to be accurate. So when you don’t clean a barrel and the copper fouling starts building up, accuracy goes out the window.
What is a wandering zero?
One of the complaints leveled against the No. 5 Mk I rifle by soldiers was that it had a “wandering zero” – i.e., the rifle could not be “sighted in” and then relied upon to shoot to the same point of impact later on. This condition is accurately referred to as an inability to zero, which would require this ability.
How far back should you mount a scope?
Three to 4 inches is about right. You must focus the eyepiece (ocular lens), and thus the reticle, on every new scope.
What is eye box?
noun. 1A box that provides a means of viewing or observing in a particular way. 2The volume of space within which an effectively viewable image is formed by a lens system or visual display, representing a combination of exit pupil size and eye relief distance.
Does eye relief change with magnification?
Also, note that eye relief slightly changes depending on what magnification you’re on. To get the best eye relief at any magnification, split the difference between the high and low eye relief numbers found on the specs sheet.
Do scopes hold zero?
While there is always a chance that the scope can be defective if it doesn’t hold zero, it is very rare these days. In a high percentage of the situations where people have issues with their rifle/scope combination not being able to group, most can be traced back to several other possibilities other than the scope.

Do vortex scopes hold zero?
Even after all that, I know it will holds its zero. Its not Vortex’s best or brightest scope, but for the money spent its the perfect fit for what I do with it. Plus no matter what, Vortex will stand behind it if something were to happen.
How much is 1 click on a scope?
Adjustment per click is, how many centimeters/millimeters will move on the target at 100m when you make one click on the turrets for elevation or a point of impact windage on the rifle scope. Clicks are usually specified in MRAD (1mrad is 10cm / 100m) or MOA (1MOA is 2.9 m / 100m).
How many inches is .1 mil at 100 yards?
Thus, 1 MIL at 100 yards is equal to 3.6” inches and 1 MIL at 100 meters is equal to 10 centimeters.
What does MOA stand for on a rifle scope?
MOA stands for the Minute of Angle, which correlates to the minute hand of a 360-degree clock face. Each minute refers to 1/60th of a degree, similar to the minutes of an hour. When shooting, even a slight angle can cause you to miss the mark, so fine-tuning your MOA to the precise angle or “minute” is important.
Does a dirty rifle barrel affect accuracy?
This bore insists on a certain amount of buildup to group tightly. This is really quite unusual; copper fouling is the enemy of accuracy and for a rifle to shoot its best it has to have a clean bore, but there always seems to be an exception.
How does barrel crown affect accuracy?
The answer is: Yes. Overall, damage to the crown makes the rifle less consistent, but in all but extreme cases, the rifle may still be accurate enough to continue using at reasonable ranges. So the advice to pamper your barrel’s crown is well-founded. Do not clean it from the muzzle end—clean it from the chamber end.
What causes barrel pitting?
A good and regular cleaning regime extends the life of a barrel and ONE of the main causes of pitting is moisture. If you go from a cold environment to a warm one then condensation on the outside of the barrel indicates condensation on the inside, mix that with carbon and you get acid. You also get rust.
How close can a scope be to the barrel?
Our recommendation is no less than 1/8th of an inch of clearance between the bottom of the objective and the top of the barrel. Your second choice (0.160) [for scope base height] will give you enough clearance.

Are illuminated scopes worth it?
An illuminated scope does not improve or alter the image of the target. Rather, an illuminated scope only alters the brightness of the reticle. This can be useful in low light conditions and when the coloration or lighting of the target makes the reticle difficult to see.
How far back should scope be ar15?
Center your eye behind the scope. Move it backward until the picture is as clear of the shadow as possible. Most scopes have an eye box around 3 or 4 inches behind the eyepiece.
