Why Upgrade Your AR-15 Upper?
There are many reasons to consider upgrading your upper receiver. For one thing, if you’re left-handed, switching to a receiver designed specifically for left-handed people would be preferable for obvious reasons.
But there are other reasons to consider before upgrading your AR-15 upper receiver. For one thing, you may want to go with an upper receiver that utilizes more durable materials. You may also want to improve the shooting performance out of your AR-15. And then go with an upper receiver that offers a better barrel or a longer gas system length.
Another reason to upgrade your AR-15 upper receiver is for legal purposes. You may need to remain in compliance with the gun laws of states that have tougher gun control laws, such as Hawaii, Illinois, New Jersey, New York, or California. Many of these states will have special requirements on what you can have and can’t have on your AR-15, if you can even legally own an AR-15. So, it’s up to you to research the laws in your state and confirm that you are in compliance. For example, some states may restrict how long the barrel can be on an AR-15.
What Are the Components of an AR-15 Upper?
Before you buy a new upper receiver, learn first the components of an AR-15 upper receiver. The receiver should consist of a barrel, handguard, and bolt carrier group (BCG).
The barrel of your AR-15 is the central component of the upper receiver. The part that has the most direct impact on the shooting performance and accuracy of your rifle. The specific part of the barrel that has the most direct impact on the shooting performance of your rifle is the twist rate or the number of inches the bullet will travel to complete a rotation. A 1:7 twist rate means that the bullet will travel 7 inches before completing a full rotation, for instance. Generally speaking, a 1:8 twist rate barrel will be the most versatile for 5.56 bullets with a weight of 55 to 70 grains.
The handguard is designed to protect your hands from the barrel. It also usually consists of rails that will allow you to add scopes, red dot sights, flip-up open sights, slings, lights, lasers, and so on. If possible, try to get a left-handed upper receiver that has free-floating rails. Which will provide your AR-15 with greater accuracy.
Bolt Carrier Group
The AR-15 bolt carrier group (BCG) is the heart of your rifle and the component that makes the rifle functional. The bolt carrier group consists of the gas key, bolt, extractor, and firing pin, and rests in the inside of the receiver. The BCG is often the component that will not only determine whether your AR-15 is functioning reliably but also if it is functioning smoothly.
Stripped Upper Receiver vs. Complete Upper Receiver
Whenever you go to buy any kind of an upper receiver for your AR-15 rifle, you’ll always have to choose between getting a stripped upper or a complete upper.
A complete upper receiver means that the upper receiver comes with every component of the upper receiver. which would include all the components that we discussed previously. A stripped upper receiver is just the opposite and doesn’t come with everything. For example, stripped upper receivers will often not come with a barrel, handguard, or gas system. So, you’ll need to buy and install those components separately.
There are pros and cons to going with either a complete or a stripped upper and there’s nothing wrong with going with either one. The main benefit to a complete upper is that it comes with everything that you need at once. There’s no need for you to buy or install anything else, and you can install the upper on your complete lower right away to have a functional AR.
The advantage of a stripped upper receiver is that you can customize the rifle the way you want it. Yet, you will need to purchase and install the parts separately yourself or otherwise have a gunsmith do it. Which takes more time and money, and you won’t have a fully functional upper right out of the box either.
After choosing between a stripped upper receiver or a complete upper receiver. Then, you’ll then need to choose what type of receiver you’ll want when it comes to manufacturing type.
An AR-15 upper can be billet machined, forged, or cast. A forged receiver is heavier, but also the most durable and sturdy. Machined upper receivers are the most lightweight option but are not as durable or long-lasting. Cast receivers are a good compromise between the two.
Any upper receiver that is either built out of some type of steel, such as stainless steel, for example, or aircraft-grade aluminum, will be durable over the long run. The receiver will become even more durable if it’s been coated in an anti-corrosion material, such as Cerakote or a hard-coat anodized finish.
Barrel and Gas System Length
If you go with a complete upper receiver, you’ll also need to choose which barrel and gas system length you want. AR-15 barrels can vary dramatically when it comes to length, from as short as 7.5 inches up to 24 or more inches, with 16 inches, 18.5 inches, and 20 inches being the most common. The longer the barrel, the greater accuracy and bullet velocity will be. Of course, you’ll be sacrificing maneuverability in tight conditions. So, a longer barrel won’t be suitable for close-quarters home defense or for hunting in thick brush. Whichever barrel you choose is up to you based on your preference and needs.
For a gas system, you can choose between pistol-length, carbine-length, midlength, and rifle-length gas systems. It is traditionally believed that AR-15s will function slightly more reliably with each increase in gas systems. This is why even though most 16-inch barreled AR-15s have a carbine length gas system. It’s considered preferable to go with one that would have a midlength gas system.
