Frequently Asked Questions

Does this include a lower receiver? No, this is sold as a complete upper only; a compatible lower is required to complete a firearm.

Can I build this into a rifle-configured firearm? This upper’s barrel measures 14.5 inches, under the 16-inch federal minimum for rifles. Pairing it with a shouldered rifle-configured lower without an approved NFA registration would create a Short-Barreled Rifle; it is legal to build as a pistol on an unregistered lower or as a registered SBR.

What caliber is this upper chambered in? It is chambered in 6mm ARC.
