Types of AR-10 Upper Receivers

Based on the design, profile and construction, there are different types of AR-10 uppers. Let’s take a look at why each model is unique.


With or without forward assist, AR-10 uppers are generally available in two different designs, namely the carry handle and the flattop.

The carry handle is not really used these days because of the limited customizability and its rear sight assembly.

Flattop Upper

Flattops, on the other hand, are more prevalent because of its wide range of accessories available.

Some upper receivers also feature a forward assist button. The forward assist helps you push the round into the chamber if you do not want to make that ‘loading click’ sound of your charging handle.

Profile (Low Profile vs High Profile)

Older versions of the AR-10 receiver are high profile. They feature a 3/16" wide, top portion where the charging handle is installed and .210 tang.

On the other hand, the low profile versions are slicker and more versatile. Also known as the DPMS style receivers, they have a 1/8" wide, top portion where the charging handle is installed with .150" upper tang.

Due to their versatility, users can club low profile receivers with a lot of aftermarket accessories. It’s important to note that high profile uppers are not compatible with low profile lowers and vice-versa.

Construction (Forged, Billet or Cast)

AR-10 uppers can be manufactured using different techniques including forging, billet machining, or casting. Each of these methods churn out uppers of different qualities and characteristics.

Billet Upper

Forged receivers offer more strength, whereas billet receivers are considered to be more precise.

Manufacturers also use polymer uppers these days due to their lightweight and easy machining capability. However, they are not recommended for heavy calibers like .308 of the AR-10.

What Makes a Great AR-10 Upper Receiver?

A great AR-10 upper receiver comes with some clear characteristics. They are:

Design (Flat Top vs Carry Handle)

AR-10 receivers are available in two basic designs: flat top and the carry handle. You can also consider the difference between the A1, the A2, the A3, and the A4.

A carry handle design requires mounts and adapters for adding scopes and other accessories. Additionally, the carry handle cannot be used very often because it houses the rear sight assembly.

On the other hand, the flat top (DPMS version) offers more versatility for adding accessories, and the top-mounted Picatinny rail can easily mount attachments like scopes and lasers.

Style (Forged vs Billet vs Cast vs Polymer)

Forged metal is always considered to be more durable and tough. The same goes for the AR-10 uppers. Indeed, a forged upper will be more durable than a billet machined one.

However, billet uppers are aesthetically pleasing and offer more room for decoration. Billet receivers are a bit more expensive, but they also help with improving your accuracy.  

Eventually, forged and billet uppers do not differ much in terms of durability. Furthermore, because of their brittle nature, receivers cast from aluminum must not be used.

Finish (Complete vs Stripped Upper)

Upper receivers are available in complete finishes, as well as striped finishes. If you like machining and customizing your accessories, you can purchase a stripped AR-10 upper.

On the other hand, a complete upper comes with the ejection port and forward assist button pre-installed.

Additionally, a complete upper will save you time and won't come with the issues of FFL as with lower receivers.
