It’s no secret that the AR-15 is one of the most popular firearms on the American market to date. Its accuracy, versatility, and the awesome lightness of its build make it a gun for all seasons, and that modular construction gives you all the room you need to fully customize your gun using any attachments you like.
Now, there are thousands of great pre-fabricated AR-15s available on the market. Obviously, many gun owners prefer to handle the assembly on their own, with parts and accessories they choose. Whichever way you slice it, though, one thing stays the same: the AR-15’s one hell of a gun.
And one of the central elements in these weapons is the upper receiver.
AR-15 Upper Receiver
The receiver is the central component your AR-15 is built around. It consists of a top and bottom receiver. Bottoms are serialized for tracking and registration purposes. The top receiver attaches to the bottom, and the rest of the build is fastened to the completed assembly.
AR-15 assembly configurations are available in A1, A2, A3, and A4 varieties, each with their own yardage, torsional speeds, and design specifications. But enough about all of these technicalities. Let’s look at what matters most in our AR-15 build reviews.
When reviewing AR-15 build components, it’s important to be rigorous with what you look for. That’s why we took the time to factor in the following criteria:
- Quality control: The AR-15
design is a classic with a long standing in the gun community. The design
has specific specifications that are important to the way it functions.
Any upper manufacturer should commit to making sure these components are
delivered without any dangerous defects.
- Known standards of quality: The term “Mil-Spec” is pretty common in this industry, and it helps to sell guns for most companies. But it’s only a half-true description, most of the time. We made it our priority to check for true mill spec production quality.
E2 Armory: A2 Upper Receiver
A fully machined, hard coat anodized military upper is a beautiful thing, especially for fans of that classic M16 look. Available from E2 armory and precision machined from Aerospace 7075 aluminum alloy forging, this A2 Upper Receiver is a high-quality, highly customizable component that looks as great as it performs.
But let’s take a closer look.
Uppers arrive 100% ready for any configuration of barrel, carrier, bolt, forearm, and lower for your build. This customizable build features cuts for mounting an A2 rear sight, with an A2 carry handle style. Shell deflection, forward assist housing, and space for an ejection port cover installation give you all the space you need.
And it looks good, too. Hard anodize coating and a flat black dye combine for a sleek, understated look. On top of a non-reflective Nickel Acetate Seal, with its custom laser marked E2 logo, this makes for a great looking gun in any collection.
But, of course, we’re not just here to talk about looks all day. E2’s top-of-the-line upper receiver is Kaiser chemical composition certified for 7075 Aluminum and completely compatible with Mil-Spec AR-15 platform lower receivers. That means it’s every bit as versatile as it is durable, and that’s a level of quality you can feel just holding it.
