Frequently Asked Questions

What do I need to complete this AR upper into a working rifle?

Is the bolt carrier group included?

Yes. The Tacfire complete upper comes with the bolt carrier group installed, so you don't have to source that separately.

Is this barrel headspaced?

Yes, the upper is factory-assembled and headspaced, meaning the barrel and bolt relationship is set to correct specifications so your rifle will function safely when paired with a compatible lower receiver.

Can I use this upper with any AR-15 lower?

This upper is designed for standard AR-15 lowers. Always verify lower compatibility before assembly, and ensure all components meet your local legal requirements.
