Having the right tool for the job is vitally important. Cartridges and scopes are getting more powerful every single year, and this makes choosing the right scope even more vitally important than ever before.

On one end of your rifle scope you have the objective bell and the objective lens. The elevation adjustment and the windage adjustment are in the center of the scope. Then you have the power ring, the eye piece, the ocular lens and the exit pupil which are on the side that you look through with your scope. Knowing these terms is important when it comes to choosing the best rifle scope, because there are unique characteristics among each of them. If you don't know your rifle scope anatomy, then you are going to have trouble determining which features are the most important for you to seek out.

The main tube for most scopes in America is only a single inch in diameter, which means that they make use out of one inch rings. Some main tubes are only 30 mm, meaning that they use 30 mm rings. There are a number of different base types that can be used to connect the rings directly to your rifle. You are going to need to know what type of base you need in order to find out the height and the type for the rings that you are going to use for the scope that you want, whether they are 1" rings or 30 mm rings.

Scopes do not gather light though most people think that they do, but rather they transmit available light to your eye through the lenses, even losing some light in the process. The best scope is one that offers a theoretical 98% light transmission. Anything that is above 95% in light transmission is considered to be great, though most scopes only offer around 90%.

Another consideration is magnification range. A rifle scope with a 3 to 9 magnification range for a gun intended for whitetail deer is pretty much standard. For mule deer or for antelope, choosing a 4 to 12 or a 4.5 to 14 is not going to be too bad. High power scopes are definitely nice, but in certain situations such as on hot days, they will be rendered nearly unusable because of heat waves and mirage. For smaller animals or for longer range targets, choose a variable range with 6 to 20X or 8 to 25X for the best results. Some other people prefer fixed scopes because they have fewer moving parts and are simpler, so consider this option as well.

There are many choices when it comes to scopes for a M1A rifle and the only homework you would need to do is to figure out what suits you best and what are your needs. When it comes to scopes, there are several things that you need to consider from its eye piece, to the eye bell, to the elevation adjustment to the objective lens. All these things, and many more need to be according to what you want and how you would like your scopes to be like.

Rifle scopes are important as they magnify an image and put your eye on the same optical filed as the image you are viewing. With scopes, and image is magnified through a series of lenses within the scope. Generally, lower powered scopes are typically shorter with smaller lenses than high powered scopes.

When choosing a M1A scope, consider these two items- the field of view (FOV) and the magnification of the M1A rifle scope. With the FOV, it is basically what you see through the scope when you look through it. The wider the FOV, the better you see.

When it comes to magnification, some have variable power while some have fixed power. If its fixed power, the label on the scope will read ‘4x’ meaning that the scopes magnifies an image by four times. On a variable scope, you would find ‘3.9x, 50mm’ which means the scope enlarges the image between 3 to 9 times more, with an objective lens of 50mm in diameter. For M1A scopes, having one that is variable is nice. It allows you to adjust the magnification of an image to the situation you are in- whether in the morning where you need less power of in the afternoon where you need more power.

The disadvantage of the M1A rifle scope that is variable is that they are generally more expensive than their fixed versions and fixed versions require more frequent sighting in. Anyways, if you can afford a variable M1A rifle scope, then get one.

Apart from the magnification and the FOV, you should also consider if the M1A rifle scope is sealed, water and fog proof. A good quality scope can withstand water and fog for a longer period. Lens coating also is a very important aspect of your scope. Make sure that the scope you buy has coated lens to protect them from scratching, reduce glare and improve resolution.
