Radical Firearms 5. Rifle Supply AR 5. Radical Firearms. Spike's Tactical. Midwest Industries. The AR is a rifle comprised of two halves; the upper and lower mated together, each responsible for their own essential functions. The upper contains the bolt carrier group, and is the half of the AR the barrel attaches to, so making the right selection of upper parts to match your desired performance is critical.

A ificant advantage of the upper — unlike a lower receiver — is it's not considered a firearm by the Bureau of Alcohol, Tobacco, and Firearms. This means you can purchase the upper and have it shipped right to your door, no FFL transfer and no paperwork.

A shooter can assemble a variety of upper configurations and use all of them with the same lower. Meaning you only have "one" serialized firearm. Having two dedicated rifles is certainly an option, and if you want to get the absolute best performance from each specialized set-up, that is probably the way to go.

Many manufacturers offer a of options when it comes to AR uppers, so what are the most important things to consider when choosing your next one? What makes a good upper receiver? While there are many versions of the AR upperthe most commonly available version on the market today is the flat-topped A4-style upper that does not feature a carry handle. So, what are uppers made of? They come in a few different types of material and use different construction methods.

This makes it easier to work with in the manufacturing process, but it is not as stress-resilient or as strong as T6 which can be as hard as steel. Billet upper receiver for sale, both upper and lower, are made one of two ways; they will either be a forged receiver or a billet receiver. A CNC machine completes all the work, taking the solid block of material and trimming it down to the exact size and shape required. Some applications, such as home defense, favor a shorter barrel length so that you can clear doors and hallways with ease.

If you want a shorter AR, we recommend looking at a caliber like. The most common barrel length for a 5. After the initial size and shape has been achieved, the receiver is then finished on a CNC machine. It is generally agreed upon by metallurgists that, because of the compressive forces involved in the forging process, a forged receiver is stronger than a billet receiver. The shaping of the receiver under pressure causes the grain of the metal to follow the same shape as the receiver itself, providing for continuous grain characteristics in the overall product.

These are by far the lightest of any aluminum receivers, but also very much the weakest. They are made by pouring liquid aluminum into a form, or cast, and letting it solidify. These are usually finished on CNC machines as well. There are also a few special cases where companies will offer polymer uppers, usually reinforced with metal in key places. These are far less common than lowers made of polymer which are rising in popularity and viability as a cost-effective option, and they are only a viable option for uppers if you are looking to build or convert an AR in. Stripped uppers are the most affordable and offer the AR builder a chance to customize every aspect of the build with custom-selected parts.

A stripped upper DOES NOT comes with a bolt or carrier, a barrel, a port cover, a parts kit, a charging handle, a gas system, a handguard. A stripped upper is the most base part when assembling your own upper receiver. The assembled uppers include small parts such as the ejection port door and forward assist already installed on the upper receiver. A great place to start if you don't want to mess with tiny springs in the port cover, and forward assist. Barreled upper assemblies come with the barrel already attached and generally include a drop in or free-floating handguard installed as well.

These assemblies will also come with gas systems in place at a specified length. It is important to note, these barreled upper assemblies will not Billet upper receiver for sale a bolt carrier group or a charging handle, and those will have to be purchased separately. These assemblies come ready to be taken out of the box and mated with a complete lower receiver to form a complete rifle. Lots of owners will have several complete upper receivers, some with different length barrels, different calibers, or particular features, and have just one lower that accepts them all.

American soldiers overseas were seeing their rifles jam or fail to go fully into battery on a frequent basis, so the forward assist was added, along with a scored bolt carrier to allow the assist button to press the bolt forward manually.

Older ammunition had a high carbon content that led to frequent buildups inside the bolt carrier compartment and chamber. This caused the issues which made the forward assist necessary. Today, many will dispute the relevance of a forward assist, but the feature provides an additional level of control with negligible trade-offs.

Located on the same side as the forward assist, the ejection port allows for the spent casing in the chamber to be removed and flung out of the receiver by the extractor. This happens as the bolt carrier group slams rearward, cycling the firearm and stripping a new round into the chamber as it returns forward. These can come already installed on a receiver or may need to be purchased separately.

The MIL SPEC dust cover is made of aluminum, but many companies are offering custom dust covers for extra personalization and functionality. These are made of polymer and feature a proprietary de that seals the ejection port more securely from dust and debris and are also built to attach and detach much easier than MIL SPEC dust covers. The polymer construction allows the port to simply snap into place and function just the same as MIL SPEC covers that must be attached with a full-length pin that extends through the assembly.

It is also completely resistant to rust and corrosion, and will never fade in color like metal dust covers often can. If you are considering an upper that will be used with big bore AR cartridges, such as. The standard size dust cover will still fit properly over top of an enlarged port. Located just behind the ejection port, and in front of the forward assist on models that feature them, is the shell deflector, or brass bump. While the Military stipulates that all upper receivers are hardcoat anodized in black, and this process has become standard industry practice for its durability and corrosion resistance, many manufacturers are offering their uppers with a variety of color options and coatings.

The anodization process can also be used to impart certain colors onto receivers, giving you some flexibility beyond the standard black finish. These coatings go over top of the anodization and provide some additional protection and wear-resistance. Billet upper receiver for sale handful of manufacturers, like WMD Guns for example, will use a Nickel Boron coating, similar to the coatings that are popular on internal AR components, for a unique looking finish and excellent wear and corrosion resistance. Keeping in mind that uppers come as either stripped, barreled, or complete assemblies, there is a considerable amount of price difference between types.

The cheapest way to purchase an AR upper is to buy a stripped version and add the parts yourself. Barreled uppers will generally be more expensive, but not quite as expensive as complete uppers.
