The AR platform is incredibly popular and versatile, but it’s important to understand that “AR” doesn’t exclusively mean “AR-15.” While the AR-15 is the most common variant, the AR platform encompasses a broader family of firearms with shared design characteristics. This blog will explore some of the key AR platforms and their unique features.

- Large-Frame ARs: These platforms are designed for even larger and more powerful cartridges, such as .338 Lapua Magnum and .50 BMG.
Understanding the Differences
It’s important to understand the differences between these AR platforms to choose the right firearm for your needs. Consider the following factors:
