Frequently Asked Questions

Does this barrel come with an upper or lower?
No, this is a bare barrel only; it does not include an upper receiver, lower receiver, or gas system parts.

Is a 5.5-inch barrel legal to buy on its own?
Yes. A bare barrel isn’t a regulated firearm by itself. It only becomes a short-barreled rifle if it’s assembled onto a complete, shouldered rifle lower without prior ATF approval.
