Upper Receiver Parts

What are Upper Receiver Parts?

Upper Receiver parts are any part that can be used to complete an upper receiver group. This can be anything from a barrel, to a dust cover, to a bolt-carrier group. While some builder like to buy complete upper receivers, and have everything ready to go out of the box, a lot of people choose to go with a stripped upper receiver, so they can build their rifle to their exact specifications. For example, while a 16" barrel with a carbine length gas system is the most common upper sold today, many shooters may want a mid-length gas system instead, or perhaps a shorter barrel for home defense. Buying a stripped upper and then your own Upper Receiver parts allows you to build your rifle exactly how you want it!
