Why use a Scope with Your AR-15?

A good quality scope can help improve accuracy while shooting with an AR-15 rifle by providing better aiming points especially at longer distances. A proper magnification level will allow you to see targets clearly even from far away while still keeping them visible within your field of view.

Features To Consider When Choosing The Right Scope

Before diving into our top picks let's look at some important factors you need to consider when selecting a scope:

1) Magnification: This is perhaps one of the most crucial aspects as it determines how well you're able to aim at distant targets.

2) Reticle type: There are different types of reticles such as crosshairs or dots which help centering your target effectively

3) Durability: Choose scopes made out materials like aircraft-grade aluminum which offer durability and ruggedness against harsh conditions

4) Objective lens diameter: It affects how much light gets transmitted through hence clearer image visibility

Now let's take a closer look at our top picks:

Vortex Optics Viper PST Gen II First Focal Plane Riflescopes

The Vortex Optics Viper PST Gen II is undoubtedly one of the best scopes available in terms of its features & technology used. With its excellent optics system offering crystal-clear image clarity even during low light conditions along with its first focal plane reticle system, you are sure to get the best shooting experience.

Choosing the right scope for your ar 15 requires careful evaluation of various factors like durability, compatibility and clarity among others. All these scopes mentioned above meet these criteria and have received high praises from shooters worldwide.
It’s important to find one that fits well within your budget without compromising quality or performance so take some time comparing prices before making a final decision!


What is the best scope for an AR 15?

When it comes to choosing the best scope for your AR 15 rifle, there are a lot of factors that come into play. The first thing you need to consider is what type of shooting you will be doing with your rifle. Are you planning on long-range target shooting? Or are you using it primarily for hunting?

One popular option among AR 15 enthusiasts is the Vortex Optics Viper PST Gen II riflescope. This scope features a versatile magnification range and crisp, clear optics that make it ideal for both hunting and tactical applications.

Another great option to consider is the Trijicon ACOG (Advanced Combat Optical Gunsight). This sight was originally designed for military use but has since become popular among civilian shooters as well. It offers excellent durability, clarity and speed in target acquisition.

Ultimately, when choosing a scope it's important to do your research and find one that meets your specific needs.

What magnification should I use on my AR 15?

The optimal magnification level depends on what type of shooting activities you're engaging in with your rifle. For close-range engagements or quick target acquisition situations such as CQB (Close Quarters Battle), holographic sights or red dot sights will be more appropriate than scopes since they offer unlimited eye relief (for rapid targeting) along with parallax-free aiming reticles which helps to reduce aiming errors caused by incorrect head position behind optic; while higher end models may also have adjustable brightness settings allowing them adjust according to lighting conditions.

If however, long range precision shots are required then low power variable optics such as those between x1-x4 can work adequately at ranges up-to around two-hundred yards provided they feature true daylight bright illuminated reticles thereby enabling better accuracy even under poor lighting conditions.

For longer distances beyond this point its recommended moving upto scopes offering higher magnifications ranging from x6 to x12. These scopes ensure you can accurately engage targets up-to 600 yards and beyond, although higher magnifications are possible they may cause image distortion thereby reducing clarity of images making it harder to acquire targets.

Can I use a hunting scope on my AR 15?

Hunting scopes can be used on an AR 15 rifle, but there are some things you need to consider before choosing one. Hunting scopes tend to have lower magnification levels than tactical riflescopes since most shots taken during hunting will be at closer ranges than what is usually seen in tactical shooting situations such as between fifty and two-hundred yards or perhaps more; whereas tactical scopes offer increased magnification for longer distance engagements.

Additionally, since AR-15s generate significant amounts of recoil with each shot fired due its semi-automatic operation mechanism within the rifle; therefore it's important that your scope is able withstand this recoil so look for models specifically designed for rugged usages like those using aircraft-grade aluminum body construction / built-in shock-proofing mechanisms which protect against any damage from vibrations caused by repeated firing cycles.

It's also worth noting that the reticle reticles should ideally feature hash-marks or similar sub-tensions at various distances as these help improve accuracy while compensating bullet drop over varying distances encountered in real-world scenarios.

What is eye relief and why is it important?

Eye relief refers to the distance between your eye and the eyepiece of a scope where you're still able see through the optic properly. It plays an essential role in ensuring proper form when taking precise shots because incorrect positioning behind optic can lead aiming errors causing missed shots under some situations thereby rendering whole sighting exercise useless.

Having sufficient eye relief helps prevent "scope bite," which occurs when there isn't enough space between your face/eye & rear end of scope leading gun recoiling back into shooter’s face sometimes causing injuries if protective gear not worn correctly eg, shooting glasses and ear protection.

Eye relief also makes it easier to acquire your sight picture quickly and accurately. It's important to note that the amount of eye relief you need may vary depending on what type of shooting you're doing or rifle being used. Therefore, it's always best practice to check manufacturer instructions regarding proper positioning while firing so as not gamble with one’s safety.

What is parallax and why does it matter?

Parallax refers to the apparent movement of an object when viewed from different positions; specifically in scopes this is where reticle center appears shift away from target under less than ideal aiming position due movement or wobbling.

A scope with a parallax error can lead missing shots at relatively closer range since shooter will be sighting off-center thereby causing missed shots leading poor accuracy; however, if you're trying make precise or long-range shots then having zero-parallax (parallax-free) scope helps ensure eliminates any chance of such errors incurred during target acquisition.

When looking for a scope, consider choosing one that has adjustable parallax correction features built-in which allow adjusting for different ranges encountered in real-world scenarios helping maintain better focus thereby improving overall shot placement accuracy especially under situational variances eg: varying lighting conditions etc.; simple devices like objective lens side-focus dials help remove concern about any error caused by such variables providing more accurate aiming solutions without fiddling around too much while still maintaining greater flexibility over targeting distances encountered during typical hunting scenarios making them popular options among many shooters today
