Product FAQ

Q: Will this work with my upper receiver?

A: The barrel assembly will work with any mil-spec upper receiver. If you have a left hand upper receiver, please make sure to purchase the barrel with an ambi barrel extension to ensure the bolt will properly lock into the barrel extension.

Q: Do you provide instructions on how to install the barrel?

A: Unfortunately we don't provide directions on how to install a barrel and recommend that it be installed by a gunsmith to prevent damage to the rifle.

Q: Do I have to purchase a matched bolt to my barrel?

A: With AR-15's as long as you are using the proper bolt for the caliber you do not need to match a bolt to the barrel.
