Side Charging AR15 Upper Receivers Review: A Brief Introduction

A side charging upper is a lot different from your regular AR-15 charge. A regular AR-15 charge comes from the rear of the rifle. In order to charge, you will have to pull back on the charging handle that extends from the back of the receiver. As a result, the bolt is retracted and it causes the gun to cycle.

For obvious reasons, a side charging AR 15 allows you to perform the same charge. The difference is that the charge will be coming from the side of the AR-15 rifle, not its rear. Upper receivers have a groove that can accommodate the charging handle. These are situated on the left side.

This will need a specially-made Bolt Carrier Group (BCG) in order to run properly. This bolt carrier group can be bought separately. You other option will be that if you have a currently existing bolt carrier group, you can modify it with the right kind of setting to accommodate the side charger.

The Expectations for AR-15 Side Charging Upper

Of course, you will be going to experience some advantages when upgrading to a side charging  AR 15. What really sets this apart from the regular version though? Here are a few advantages that you can expect:

Great Aesthetics

There are quite a handful of gun owners who will often use an AR-15 side charger for the sake of its looks alone. If you are one of those gun owners who wants it for the sake of this advantage, we won’t blame you. A lot of gun owners want a cool-looking rifle that will turn heads at the range. However, don’t forget that a gun’s functionality should always be one of the main items of importance. You are not carrying around your rifle just to show off its looks, are you? Of course you’re not.

Fewer Malfunctions

There will be a time when you will deal with a malfunction or two. Your rifle may jam or the cycling will not be as reliable as it once was. In that event, you will be able to clear a jam and charge your AR-15 rifle without changing positions or breaking the rifle.

Rifles Will Still Function The Same

Even with a side charger, you will be able to operate your AR-15 rifle as you normally would. This also means that you won’t have to make any permanent changes to your rifle. And you don’t need to add on any additional parts (or get rid of any) to it. Your rifle will fire and function just as it normally would. The only difference is the style of charging the rifle.

The Criteria for The Best Side Charging AR Upper 

The most important thing you need to do as you are looking for in a side charging AR 15 is to make a few merits. One of them is taking note of a great side charging AR 15 from one that is considered cheap and inexpensive in quality. Yes, there are some differences in features and functions between a great side charging AR 15 and one that is not as great. Here are what you need to look for as your search begins:


As a budget gun owner, you are always going to look at price as being one of the biggest factors in your buying decision. It should not be the only reason you should buy a side charging AR 15, though.

One of the criteria that should be placed as a high priority over price should be the quality. There are high-quality side charging AR 15 priced within your price range. However, some price tags are low for a reason: they are of low quality and can break easily. Choose carefully if you are on a budget.


One of the things you need to ask is whether or not a side charging AR 15 is well-matched with your currently existing bolt carrier groups. If so, it is possible some alterations might be needed. Your other option is that you may need to consider purchasing a special bolt carrier groups to put up with these side charging uppers. When considering either choices, find out which one will be cost-effective on your end so you won’t have to spend more than what you planned for.

Build or Upgrade

Another question that gets frequently asked is this: Is it better to get a side charging upper when you are building an AR-15 rifle from scratch? Or is it all right if you have a currently existing rifle? If you are building one from scratch, it will be a lot easier to install a side charging AR 15 since you may not have a BCG to fit it just yet.

If you already have an AR-15 rifle, the odds are that you may need to consider what was previously stated: either changing your current BCG or getting a new one that will work better with side charging AR 15 receivers.
