UPPER RECEIVERS
How to Build an AR15 Upper Receiver.
For most shooters, building an AR 15 is a bucket-list item. It's right up there with shooting a .50-cal or hitting a bullseye at 1,000 yards. And it makes sense. AR rifles are easy to modify and reconfigure. The parts are standardized and largely interchangeable. That's why we put together a series of guides on How to Build an AR15. image Taking a bird's eye view, an AR consists of two halves. The bottom half, the lower receiver, houses the firing controls like the mag well, safety selector, and of course trigger. And then the top half, the upper receiver, is where the magic happens. It's home to the chamber, bolt-carrier group, barrel, and more.
