What’s an AR-15?

Why Choose an AR-15?

Well, frankly speaking, it’s the most popular hunting rifle out there.

The AR-15 has various impressive features. From its shooting abilities to its versatile modular design, you can surely create an AR-15 that suits your personality. Although, creating an AR-15 will require you to at least know what you are buying. This guide will help you with that.

Now, not everyone likes to build an AR-15 part by part. There are people out there who prefer premade ones offered by various brands like Colt, LWRC, Bravo Company, Daniel Defense, etc. These brands offer different types of AR-15s which, of course, differ in price.

They say that there are always two kinds of people in this world. Well, actually there’s always THAT third person.

If you don’t currently own an AR-15 but constantly read news about guns and buy magazines about guns (or, in other words, an enthusiast without a gun), you might be that third person. The person who wants a custom AR-15 but does not like to spend much time building one from scratch. We suggest you get a full upper and then create your own lower.

Who Makes The Best AR 15 For The Money?

Choosing the right gun depends on your budget and preference. The DDM4V11 Pro sure looks great on paper, but what matters most is how you will use it. If you have the money, buy it. But if you would want to experience the overwhelming modularity of the AR-15, we suggest you buy the S&W M&P 15 Sport 2 and upgrade your way. Even if you buy a top-quality AR-15, the gun’s quality will still solely depend on how you use it, how often you clean it, and how you maintain it.

Editor’s AR-15 Choice: Smith & Wesson M&P 15 Sport II 


As a first-time buyer, we recommend you to get the lowest high-quality AR-15. The same performance can be attained, regardless if you go for the cheapest or the most expensive AR-15. The more you learn about AR-15s, the more you’ll understand that this gun isn’t just a ‘What you see is what you get’ deal. It is meant to be upgraded and changed throughout. Take advantage of the modular design – and remember that the cheapest option will give you the most headroom when it comes to upgrading.

Where to Buy an AR-15 Rifle? 

Local Gun Stores

Buying from your local gun store might not be the best if you’re after savings. The advantage here though is that you can actually ‘feel’ what you’re looking at.

Online Stores

Buying online is very convenient and you can easily compare prices. You can always get the lowest-priced gun. The only drawback is that sometimes, shipping can be a hell of a nuisance.

Getting your items and knowing that there’s a defect means that you will have to return them. Although, return policies and money-back guarantees are pretty much offered by most online stores. This could give a better assurance that you’ll not spend your money on anything.

Basic Gun Laws for AR-15’s 

Since we cannot cover every gun law in every country, we’ll address the gun laws present in the United States ‘Federal Assault Weapon Ban.

The AR-15 is LEGAL as long as the minimum barrel length of your gun is 16” such as what you would find on a hunting rifle. Going below the said length will result in trouble. If you have other attachments, those should be permanently attached to the barrel in order to meet the minimum barrel length. First-time buyers may want to get a 16” barrel to avoid such trouble. Remember: not having the required documents will result in your gun getting confiscated.

What Are The Parts of an AR-15

An AR-15 has two main parts: the Upper and Lower (if you’re going to build one from a scratch, you’ll end up with a lot more specific parts to consider and know). In this guide, we will be talking about the importance of each.

  1. Upper Parts (Upper Receiver Parts)
  2. Lower Parts (Lower Receiver Parts)
  3. Barrels
  4. Gas Systems (Piston vs. Direct Impingement)
  5. Bolt Carrier Group
  6. Muzzle Devices
  7. Accessories

Now since this guide is focused on readers who have no idea what to buy, we will not cover everything from pins to rolls to springs. Rather, we’ll cover the most important parts of an AR-15 and discuss ways on how to choose carefully.

Upper Parts (Upper Receiver Parts)

Regardless of which company made this part, it still serves the same basic purpose – you’ll only be choosing based on aesthetics. Performance-wise, it does not affect the gun’s functionality drastically.

Things are a bit different if you’re left-handed. You might want to change the charging handle to appease your dominant hand. Buying from known companies is always a better choice for they manufacture parts that always meet the required specifications.

Lower Parts (Lower Receiver Parts) 

Choosing the right Lower Parts means choosing the right materials. Lower parts are usually made from 6061-T6 to 7075-T6. These are all aluminum alloy bodies. Always choose the 7075-T6 material since it is better than 6061-T6. Surprisingly, their prices don’t differ that much.

Combining the Upper and Lower means that both should have the same finish. Coatings provide protection against abrasions and corrosion (although gun maintenance should be done often). There are coats like Duracote and Cerakote that offer different colorways other than your regular, good ol’, black finish.


Now, this is where everything gets a little bit tricky. You should NEVER cheap out on this part. The Barrel affects both longevity and accuracy.

The Barrel is bolted into the upper receiver. It has a barrel extension that should fit in the upper. The barrel is made to support specific cartridges depending on what you get. The regular for an AR-15 is a .223 Remington and a 5.56 NATO. A barrel that is purposed for a .223 Remington can only shoot a .223 Remington, while a barrel with a 5.56 NATO and .223 Wylde indicator can accept and shoot both.

Hosting different rounds will require you to have a different barrel, bolt carrier group, and magazine to safely shoot these rounds.

In choosing barrels, you have to consider the linings, materials, and finishes. It needs to be well-constructed because it is expected to hold a lot of stress and heat. A well-built barrel avoids failure and premature wear. Lining materials such as chrome and melonite are quite popular and are also our recommendation for first-time buyers. Barrel materials consist of both carbon and stainless steel. We recommend 410 stainless steel.

Barrel lengths should also be considered and chosen wisely. As we discussed in the laws above, your barrel should not be below 16” in length. In getting your first AR-15, we recommend either 16” or 18”. It will solely depend on your practice. You can always customize your barrel if you feel like it.

Above all, it is always better to buy from a respectable manufacturer for they will, most of the time (not always), give you the best quality component.

Gas Systems (Pistons vs Direct Impingement)

A gas system explains how your gun works. An AR-15 works by sending the gas behind the bullet proceeding into the gas tube and either sending it back or moving a piston.

It renders the bolt to unlock, set back, release the used casing, and put in a new bullet inside the chamber. Almost every AR-15 uses DI.

There are lots of gas block profiles but the one we can recommend is the Front Sight Base-style gas block – a combination of both Front Sight and Gas block.

Bolt Carrier Group

The BCG contains the firing pin, bolt carrier, and of course, the bolt. The bolt is the one responsible for taking out used bullets and setting in new ones. The bolt carrier is the one holding the bolt inside and is responsible for docking the gas tube. It also resets the trigger. BCGs are part of the upper receiver.

Muzzle Devices

There are a lot of muzzles available in the market. Let’s discuss the three basic ones.

  • Flash Suppressors, by the name itself, eliminate the risk of you being blinded by the flash from your muzzle when shooting.
  • Muzzle Brakes reduce recoil by redirecting the gas out of your gun. We recommend you use one if you feel uncomfortable with your gun’s recoil.
  • Hybrids are a combination of different muzzle devices. The best example would be an A2 Style, Flash Hider.

Most AR-15s are equipped with an A2 Style Flash Hider. You don’t have to worry about what to choose, to be honest. You can change the parts later on.

AR-15 Accessories

There are many options when it comes to accessories. You don’t have to bother much them, but choosing the best accessory often means choosing the best finish and build quality.
