One thing that always baffles me when I enter into any gun store is how I realize most of the rifles lack iron sights. Since rifling was invented, metallic sights have remained to be critical components of rifles. But in the recent history, there have been fewer factories equipped with iron sights. Personally, I think this is the most powerful indication of the effectiveness of rifle scopes. Having had a huge experience in recreational shooting, I have prepared a guide that I think will be crucial for buyers when choosing a rifle scope.
1. Optical Power
The optical power is perhaps the first thing that you will want to consider when choosing a rifle scope. A scope’s magnification capability is a key determinant of its usefulness. It is crucial to bear in mind that lower magnifications allow for faster and intuitive shooting experience, as well as good target tracking. On the other hand, higher magnifications allow for excellent target resolution. However, higher magnification scopes such as 16x and more will be heavier, expensive, and difficult to utilize from untenable positions.
2. Size Matters
The size of the objective lens should be the next thing to consider once you are done with the magnification capability. The objective lens is crucial to determining the ambient light so as to focus it into an image. A Larger objective lens has more ability to transmit more light to your eye, meaning a clearer and brighter image. Nonetheless, large objective lenses have their problems. Typically, you need to place them higher over the action and barrel, meaning it affects the shooting ability. Luckily, you can fix this challenge by buying some cheek-riser.
When buying a rifle scope, it is also important to consider the specs of the scope’s reticle. A good reticle for shooting targets is that features harsh marks and dots evenly spaced throughout the horizontal and vertical axis.
- Duplex Reticle. This perhaps the most common reticle used presently and were characterized by a tiny crosshair that is thicker on the outer area. Scopes of this nature are best in most shooting and hunting applications.
- Mildot Reticle. This type of reticle is characterized by size and the spacing of the dots on the reticle-line that correspond to particular angles measured in milliradians. I recommend this form of reticle to be used on the guns intended to shoot beyond 300 yards because they have the ability to retain the intuitive focus of the duplex reticle and at the same time allowing the shooter to perform accurate hold-offs and range calculation (http://www.cabelas.com/browse.cmd?categoryId=103792680 buyers guide offers an array of guns that can work well with either of the reticles).
4. Focal Plane
Modern scopes come with two different positions for the reticle within the scope. Such positions are known as the first and second focal plane or simply as FFP and SFP respectively. Most of the scopes nowadays utilize SFP reticles. If you are looking for scopes that will give you good precision, go for the FFP because they will rarely be set to low magnification in such distances.
Parallax is when the reticle seems to change its position in relation to the intended target when its head is slightly moved. Most low magnification scopes are parallax free at specific distances such as 100 yards or so. For higher magnification scopes, ensure to equip them with a parallax correction knob.
