When it comes to building your own AR-15 rifle, selecting the right upper receiver is crucial. A 5-inch complete AR upper offers a balance between compactness and performance, making it a popular choice among shooters. In this article, we will delve into the various aspects of a 5-inch complete AR upper, including its features, benefits, and considerations for purchasing one.
