Will this fit my Colt ban era rifle?

Manufacturer Answer
A
Answered by Faxon Firearms, Manufacturer from OH, United States, on February 19, 2026

This barrel will fit all standard AR-15 pattern upper receivers. Depending on the model of rifle you are replacing the barrel on, you may also need a new gas tube and handguard/forend.
