Examining the Markings

One of the easiest ways to identify an AR-15 upper receiver manufacturer is to look for markings on the receiver. These markings can include the manufacturer’s name, logo, or other identifying information.

Manufacturers typically place their markings on the left side of the receiver, near the rear takedown pin. However, some manufacturers may place their markings in other locations, such as on the top or bottom of the receiver.

The markings on an AR-15 upper receiver can vary depending on the manufacturer. However, there are some common markings that you can look for. These include:

• The manufacturer’s name or logo
• The model number of the upper receiver
• The caliber of the upper receiver
• The date of manufacture

If you can find all of these markings, you should be able to identify the manufacturer of the upper receiver with relative ease.

Examining the Finish

The finish of an AR-15 upper receiver can also be used to identify the manufacturer. Some manufacturers use a proprietary finish that is unique to their products. Others use a standard mil-spec finish that is common to many manufacturers.

The most common finish for AR-15 upper receivers is a matte black finish. This finish is typically applied by anodizing the receiver. Anodizing is a process that creates a hard, durable finish that is resistant to corrosion.

Some manufacturers also offer upper receivers with other finishes, such as a polished stainless steel finish or a cerakote finish. These finishes can provide a more stylish look for your AR-15, but they are not as durable as a matte black finish.

If you are looking for an AR-15 upper receiver with a specific finish, you will need to do your research to find a manufacturer that offers that finish.

Checking the Serial Number

The serial number of an AR-15 upper receiver can also be used to identify the manufacturer. The serial number is typically located on the right side of the receiver, near the front takedown pin. The serial number can be used to trace the upper receiver back to its manufacturer.

The serial number is a unique identifier that is assigned to each AR-15 upper receiver. The serial number is typically 7-8 digits long. The first digit of the serial number indicates the year of manufacture. The remaining digits are a unique identifier for the upper receiver.

If you are unable to find the manufacturer’s markings on an AR-15 upper receiver, you can try to identify the manufacturer by checking the serial number. You can do this by contacting the manufacturer or by searching online for the serial number.

By examining the markings, finish, and serial number of an AR-15 upper receiver, you can usually identify the manufacturer. This information can be useful if you are looking for a replacement upper receiver or if you are trying to trace the history of your AR-15.

Here are some additional tips for identifying an AR-15 upper receiver manufacturer:

• If the upper receiver is a mil-spec part, it will have a mil-spec finish. Mil-spec finishes are typically a matte black finish or a polished stainless steel finish.
• If the upper receiver is a commercial part, it may have a different finish. Commercial finishes can include a variety of colors and textures.
• If the upper receiver is a custom part, it may have a unique finish. Custom finishes can be anything from a simple anodized finish to a complex cerakote finish.

By following these tips, you can usually identify the manufacturer of an AR-15 upper receiver. This information can be useful for a variety of purposes, such as finding a replacement upper receiver or tracing the history of your AR-15.
