Billet Upper Receivers
WHAT IS A BILLET UPPER RECEIVER?
Billet uppers receivers represent the more stylized options in the AR-15 world. While forged lowers are all pressed from the same mold, a billet upper starts life as a block of 6061-T6 aluminum, where the sky is the limit as far as design and customization.
Billet uppers frequently are designed in a way to compliment their matching 80 lower receiver, or may have a forward-assist delete, or other interesting features. It all comes down to taste; What style do you like?
WHY CHOOSE A BILLET UPPER?
Not all upper receivers are made equal. Because we are able to control manufacturing from the very beginning of the process, we are able to ensure the highest quality upper receiver possible makes it to every customer's hands. We are also able to use aerospace-grade aluminum, which guarantees a billet upper receiver that will stand up to tens of thousands of rounds without excessive wear.
Our billet upper's also accept all standard mil-spec parts, meaning that you can customize as much as you like to make your rifle truly yours. Whether it's a new charging handle, or a flashy dust cover, we guarantee 100% parts compatibility with all of our upper receivers.
