The upper receiver on an AR-15 is a crucial component of the firearm. It is the part of the rifle that houses the bolt carrier group, barrel, and other key elements. The upper receiver is responsible for housing the firing mechanism and directing the path of the fired round. It also provides a mounting platform for various accessories such as optics, sights, and handguards.
The upper receiver is typically made from aluminum and is attached to the lower receiver using pins. It contains the ejection port through which spent casings are ejected after firing. The upper receiver also includes the charging handle, which is used to chamber a round and cock the rifle.
One of the defining features of the AR-15 platform is its modularity, and the upper receiver plays a significant role in this aspect. It allows for easy interchangeability of barrels, handguards, and other components, enabling users to customize their rifles to suit different purposes such as hunting, target shooting, or tactical applications.

Probably a great vid, just couldn't watch it all, sicking UN-neccessary 1980s music drove me off. Why, don't need it?
