Start Your Next AR Project Right with the Spartan Billet Lower Receiver
When choosing a lower receiver for your AR build, there are literally thousands of options to choose from so choosing the perfect lower can seem like an overwhelming task. One of the most significant differences between available lowers on the market is whether they are forged or billet.
What’s the difference?
A forged lower is one that has been formed into shape using a lot of pressure to essentially hammer the aluminum into a lower receiver shape. It is then finished off using a CNC machine. While metallurgists will agree that forged aluminum is stronger than billet aluminum, there can be some uniformity issues and the finished look isn’t as a ‘clean’ as that of a billet receiver.
Billet lower receivers for the AR15 are formed from a solid block of extruded aluminum and shaped using a CNC machine. CNC machines are able to cut precise shapes into aluminum so billet lowers tend to have cleaner lines and geometric designs. Billet receivers often have one-piece trigger guards and other custom features not available on forged lowers which is another reason why many enthusiasts choose billet lowers to complete custom AR projects.
