What Is An Ar 15 Rifle?
The AR 15 rifle is one of the most popular guns sold worldwide. AR came from the ArmaLite rifle of the company made it in the 1950s.
It is a modern and legal sports rifle to own in many US states. It looked like a military rifle, the M-16, but only fire one bullet with each trigger.
This rifle is accurate, reliable, rugged, and versatile for shooters in all weather. They use it for various hunting purposes like a varmint, big games or national matches.

How To Buy The Best Ar 15 Scope?
Many scopes in the market can confuse you when choosing, let’s consider the following factors to obtain a product that fits your shooting and budget.
Here they are:
Understanding your needs is essential when choosing the appropriate scope. Then, you save your budget, time and quickly buy products to use.
You should ask yourself about shooting environment, the range, and goals, as well as your level of shooting and bullet types. For example, you should not buy a scope that can go far beyond the bullet you shoot. After that, go out there and select your best AR 15 scope.
It indicates the range enlarging the image of the target in the field of view. For example, the 4x32 magnification will enlarge the image more than four times of the view with naked eyes.
If you shoot at long range or small target at mid or long ranges, you need high magnification. The trick here is that you can choose to buy the power change model that will give you the flexibility to shoot at different ranges.
It is a pretty important feature when you want to select a scope. A complex reticle with many functions will obscure the field, so if you never use signs on the reticle, you should not have them.
The advice is to choose the simplest viewfinder to meet your needs when using AR 15.
Shooters hunting at 50-300 yard in medium to big games often use very well a duplex reticle. A mildot reticle is ideal for tactical and competitive shooting settings, especially at long range or moving targets.
Meanwhile, a BDC mildot is very convenient for users who need to set up and quickly shoot in different ranges.
A larger objective lens can collect more light to bring a brighter image, especially in low light conditions. So, you can identify better goals, and you don't lose a shot. However, the large lens adds weight to the gun.
Not only that, a larger tube containing an objective lens allows more light transmission and more adjustment for wind and altitude.
You should consider the weight of the scope not to put pressure on your gun. At the same time, adding heavy accessories on the rifle makes your shooting handling slow, and your strength lost easily when carrying your weapon.
It is the distance you can keep the scope from your face when shooting. Since the AR-15 has some recoil, you need a product that gives you enough room not to hit your face when shooting.

Some Frequently Asked Questions
#1. How many times magnification should I have on an AR-15 scope?
As mentioned above, this depends on your hunting purpose. We have a very simple rule for you: 1x for every hundred yards, you plan to shoot with it. So if you need to sell at 1000 yards, choose 10x.
However, you should remember that the ammunition used for guns may not shoot as far as the view that the magnification of the scope provides.
#2. Is it a bad idea to zip tie a scope onto an AR-15?
Yes, it is. The scope causes a significant shock when you shoot. It can break the scopes if they are of poor quality. If you use a zip tie to attach a scope, the range will never hold zero. You pull the trigger and create a slight change of scope every time.
Therefore, a set of appropriate scope rings is suitable to receive the scope moves. People do not design zip ties for scope attachment so that misuse will damage the scope.
#3. What is the best use of the first and second focal plane scopes?
If you take part in shooting games using variable magnification scopes and do not need to adjust the accuracy at all magnifications, the first focal plane is appropriate.
On the other hand, you can use to shoot at maximum magnification or without changing power scopes with the second focal plane.
#4. How can I mount a scope to the carry handle on my AR 15?
You can mount a specially designed scope to your AR-15. You attach it through a hole in the middle of the handle and a Picatinny rail to mount the optics. These mounts also allow you to use the rifle's iron sight when they are installed.
#5. I mounted a scope to my flat top AR-15, and it is too low. What can I do to correct this?
You can use the flat top riser to fix this problem. It is a Picatinny rail that attaches to the top of the receiver and delivers an additional height of 1/2 to 3/4 inch to bring the scope up enough.
