What makes AR-15 so popular?
So, returning to discuss the previous point. There are many factors that make AR-15 a first choice among the shooting enthusiasts. The gun is super easy to handle. Anyone, even old citizens or children can readily shoot with it. It’s light weight and gentle in recoil. The gun is easy to be customized. You can add various accessories to it. The parts are convenient in assembling and easily interchangeable. The complete system uses pins, screws and threaded parts for assembly.
AR-15 Scopes: The essential accessory
As said, adding accessories is an important feature of AR 15. You can customize and equip it with different cool and useful attachments. However adding scope to your AR 15 is the most intelligent and essential decision to make. It makes your shooting endeavor more precise, accurate and convenient.
But, before you buy the one, you must analyze the need and conditions in which you are going to use your rifle. Are you are going to use it for sporting events (like shooting competition)? Are you going to use it at a particular time? Whether you are going to use it at night times or day times? What’s the usual range of your shooting? Are you going to shoot for a long distance or shorter distance? Are you going to target mostly the moving objects or stationary objects? All these points must be analyzed before you start your search. It is going to help you choose the best scope for you that serves all your purposes.
The advantages of AR-15 scopes are immense. These can be summarized as:
- Most of the scopes employ multi-coated lenses that give glare free visibility even in bright lighting condition. Thus help to enhance visibility.
- Better focussing with the specially designed reticles. The newly developed and improved reticles come with various features like distance approximation that contribute to aim far off targets with accuracy.
- Wider view and increased range.
- Night illuminated vision, some of the reticles are coming with light illumination that enables you to have accurate aiming even in dark conditions.
- Faster target capture and focus.
With all these advantages scopes make you a better shooter. The next question that must be hitting your brain cells is, how are you going to find the best scope for your AR-15? Well, the answer is in knowing the basics.
Before you start your search (maybe the offline or online research) for the proper AR-15 scope, you should be clear with certain essential features of the scopes such as eye relief, magnification, and reticle.
Have a look at the five basic factors on which performance of your rifle scope depends:
No doubt magnification is a major factor but, often it is very focusing. It’s not necessary that only a high magnifying scope will work well. In case you have to focus on far-off objects like for hunting, it becomes essential to choose magnification wisely.
The scopes come with fixed and variable magnification. If you are a beginner, you are advised to go for fixed magnification. The fixed ones don’t involve additional moving parts. Therefore, they are more rugged and accurate.Also, they are far lighter than the variable version. Use variable scope only in the situation when there is a requirement for it. Otherwise, you should go for fixed scopes.
Well, these are the patterns( mostly cross type or dotted) that you see on your scope’s lens. The primary purpose of the reticle is to aid you in focusing the targets accurately. Many times they are also called as crosshairs. Earlier, mostly simple “+” sign reticles were in use. But, now many new designs are introduced for better aiming. The popular types of reticles are Duplex, Mil Dot, BDC and Illuminated.
i) Illuminated reticle: These reticles are designed for low light condition. If you are going to use your AR-15 in the evening or night, it can be a difficult task. Even in the dense forest, there is a scarcity of light making your visibility poorer. To cover this gap, the new scopes are coming with illuminated reticle features. Some of them are offering options for different colors that allows you choose a suitable color.
ii) BDC Reticle: BDC is shortened form of Bullet Drop Compensation. These reticles are used for long range shooting and are designed to compensate the bullet drop by gravity.
iii) Duplex reticle: In the duplex type cross lines become thinner towards the intersection. It helps to see the target more clearly. Often the thicker lines( particularly in the intersection) makes the aiming a bit difficult. In some designs, you can even spot a small dot at the center.
iv) Mil-dot Reticle: Mil-dot has the cross line integrated with a little dot. These are a bit complex and need a calculation to compensate gravity and drift effects. The dots help to adjust your shooting point as per the distance. But, these reticles are mostly designed for particular types of cartilages as their design parameters are based on the weight of cartilage.
Many of you are confused with this term. Well, nothing to worry, you have learned this concept in your school. It was in your Science book, like when you put a coin in a jug and see it from above, it appears to be raised. Similarly, when you try to aim at fish in water, you have to hit a bit lower so as to hit the fish accurately. It’s all due to refraction. When light passes from denser medium to rarer medium, it moves away from the normal( and vice-versa).
Mostly when you use high power scopes the problem of parallax appears. It happens when the focal plane of the reticle and the object are offset from each other. As you shift your gaze, the reticle also appears to move. In an ideal condition, reticle should be in locked-in position, a steady. The movement occurs when the focal plane of objective and reticle is not coincident. You need to adjust the objective ring or turret for parallax compensation. There should not be any movement in reticle as you move your gaze.
The recoiling of AR-15 guns(or any other guns) is a common phenomenon that you experience while shooting. And the same can be hazardous for your eyes. You need to keep caution to protect your eyes. Eye relief is the distance between your eyes and the scope. For most of the AR 15 rifles, it is around 4 inches. This implies that you should maintain a minimum distance of 4 inches between the rear of scope and your eye to be safe. Also, the way you mount your rifle plays a significant factor in absorbing the shocks. A proper mounting is a crucial point of consideration especially if you are a beginner. Otherwise, you may end up absorbing the shocks through your eye socket than your shoulder.
So, if you are new to shooting you should:
- Go for the compact scope with a shorter length.
- Mount the gun in right way with your shoulder.
Minute of Angle (MOA)
MOA is an another technical term that you need to master to become an expert shooter. It’s a kind of mathematics behind the shooting. 1 minute of angle is 1/60th of a degree. It can further be related to the distance of your target. 1 MOA at 50 yard = 0.5 inch, at 100 yards = 1 inch, at 200 yards = 2 inch and so on. Similarly, 2 MOA at 100 yards = 2 inches and so on. You need to set for MOA when you are aiming for far off targets. The different scope has different MOA adjustment per click, like 1/4 MOA per click or 1/8, 1/2 or even 1 MOA per click. Thus, you need to adjust accordingly. Most of you may be confused with the concept of MOA; it’s a little technical. Watch
Once you start analyzing your scope in the context of these fundamental properties and features, it becomes easier for you to choose the perfect piece for your shooting endeavors.
