Frequently Asked Questions

How can one AR-15 lower receiver fire multiple calibers?

A single AR-15 lower receiver, especially one marked 'Multi Cal' like the Anderson AM-15, can fire multiple calibers by swapping out the entire upper receiver assembly. Each upper receiver is chambered for a specific caliber, allowing for quick and easy caliber changes.

What calibers can be fired from a single AR-15 lower receiver?

With the appropriate upper receivers, a single AR-15 lower receiver can be configured to fire popular calibers such as .22LR (using a conversion bolt), 5.56 NATO/.223 Remington, 7.62x39, and 300 Blackout. This demonstrates the platform's significant versatility.

What is the easiest way to change the caliber of an AR-15?

The most straightforward method to change the caliber of an AR-15 is by swapping the upper receiver. This involves removing the existing upper receiver and attaching a new one chambered for the desired caliber, a process that typically takes only a few minutes.

Is it expensive to shoot multiple calibers from an AR-15?

While purchasing multiple upper receivers represents an initial investment, shooting calibers like .22LR from an AR-15 can be very economical due to the low cost of .22LR ammunition. This makes it a cost-effective way to practice shooting skills.
