Upper Receivers

The upper receiver is a critical assembly in your AR. The upper hosts the barrel and bolt carrier group, two of the most important components when it comes to accuracy and reliability. At Bexar Arms we source premium USA made uppers so that you can make your dream build off of a solid foundation. Don't get caught with a cheaply made upper that's causing your build to throw fliers. Be confident that when you buy Bexar Arms, you're buying quality parts with superior service!
