What Are The Components of an Upper Receiver?

Like it’s lower receiver counterpart, the upper receiver of an AR-style gun contains some elements that are vital to a rifle’s overall function. Here are the vital components of an upper receiver:

Upper Receiver 

This encompasses all the individual parts listed below. Each part has its own function, though a good upper will provide quality components all-around. Contains parts like the bolt carrier group (BCG) and also the charging handle, barrel, and forend.


Obviously, without this part of the upper receiver, it would be useless. But it is designed to give you the best in overall accuracy. The barrel twist ratio will also give you a good idea of how accurate your shots will be. In this case, a very accurate Valkyrie rifle is quite impressive for something that is considered one of the best in the business when it comes to long-range rifles.

Gas System 

The gas system is comprised of the following: the gas block and the gas tube. An AR-style rifle will rely on gas to propel your .224 Valkyrie rounds. There are four lengths of gas systems: pistol, carbine, mid, and rifle-length gas systems. Each gas system has barrels that will work in conjunction with their respective gas system. For example, rifle-length gas systems work most effectively with barrels longer than 16 inches long.

Bolt Carrier Group 

Best known as the BCG, these include parts like the firing pin, cam pin, extractor, and the gas key. This part is best used for helping you reload your AR-style rifle. This will ensure that your rounds are fired and ejecting the rifle correctly.

Charging Handle 

A handle that is connected to your BCG. This is designed to pull the BCG to the rear of your rifle so you can place a round in the chamber or correct a possible malfunction. In the event of the latter, you can pull on the handle to remove the bad round and replace it with a new, functional one.

Forward Assist 

Usually added on as a cosmetic addition and pretty much useless to most AR-style rifle users. But if used, it helps the bolt function properly.

Rail System and Handguard 

After extended usage, the barrel of your gun will get hot. And it can get hot really fast. The importance of these parts is to ensure that you don’t accidentally touch the barrel or other parts of the gun. This way, it will protect you from getting burned.

Ejection Port Cover 

This part of the upper receiver is designed to make sure that your AR-style rifle is functioning properly. Also, this comes quite in handy to keep the rifle as clean as possible. The ejection port cover will prevent all kinds of dirt, dust, and debris from entering your rifle.

What Makes a Great .224 Valkyrie Upper?

Before you make the final decision in choosing a great Valkyrie upper, it is important to know what a good one consists of compared to something of low quality.

If you’re a first-time buyer, you should probably consider the advice of those who have bought these types of uppers in the past. You can look for ideas and suggestions in various gun owner forums on the internet.

But, to save you the time, here’s a list of recommendations from past buyers of what you’ll need to look for in a great upper:

What’s Included?

The first question that needs to be asked is: what is included in this Valkyrie upper? Most uppers include parts like the BCG, the barrel, and other parts that will also comprise of the upper receiver itself. Not all receivers are created equal. Some will have a few parts included and some will include only minimal parts and you may have to purchase other pieces separately.


Of course, you’ll need to install your new upper receiver in order for the thing to actually work. The key word to look for when it comes to finding accessories like uppers is “drop-in”. This means that the upper receiver will be easy to install. In other words, you won’t need to rely on your gunsmithing skills (or lack thereof) to install this.

Likewise, a professional gunsmith may not even be needed to install the upper receiver on your rifle. Of course, if you prefer to leave installation to the experts, they can install any and all types of upgrades.

Barrel Twist

As mentioned, barrels are part of the upper receiver. If you’re looking to make your .224 Valkyrie rifle as accurate as possible, it’s important to take a look at the barrel twist. The barrel twist is a ratio associated with the overall accuracy of the rifle.

Look for barrels with a twist ratio of 1:7. Ideally, ratios of 1:6.5, 1:7, or even 1:8 will be suitable for .224 Valkyrie rifles. Also, these will work with .300 Blackout rounds that weigh anywhere between 55 to about 80-grain.
