AR-15 Upper Receiver Parts

If you are building your upper receiver from scratch, make sure you buy quality AR-15 upper parts from TR-Enabling. Although you can purchase the upper as a complete assembly, many enthusiasts enjoy the customization process and give their weapons their own personal style. One of our popular custom parts is the AR-15 bolt carrier group – available in hard chrome, nickel-teflon, or our proprietary Obsidian coating with available coated hammer and trigger option.

We also supply the various parts that you need to finish your build. We have customized individual parts like the nickel-teflon AR 15 charging handle, gas tubes available in different lengths, and AR-15 barrel nut available in either black oxide (std) or nickel-teflon. At TR-Enabling you can customize the look and performance of your weapon with affordable high quality parts and accessories.
