Understanding the Anderson Stripped Upper Receiver
The Anderson Manufacturing AM-15 stripped upper receiver is a crucial component of the AR-15 platform. It's the top half of the receiver, housing the bolt carrier group and providing the mounting point for the barrel, handguard, and other accessories. "Stripped" signifies that it comes without a forward assist, ejection port cover, or charging handle—allowing for customization and selection of preferred components.
