Customizing your AR for a caliber-specific scenario is as easy as pulling two pins. The modular characteristics of the AR platform make it one of the most versatile weapons systems ever designed. You can swap out upper receivers for a specific need, like CQB and home-defense work, or change the caliber to hunt medium- to large-sized game.

Complete upper receivers give you a choice—longer barrels for long-distance shooting, shorter barrels to work in close quarters.

The options are endless, and life is too short to just shoot your rifle with one upper installed. Here are a few upper receivers worth considering.
