A fixture for use with AR15/M16 type firearms is provided herein. The fixture is made up of several parts that when used in conjunction with one another mitigate the transfer of torque from the barrel nut to the firearms receiver during barrel installation. The fixture affords the user a method and apparatus that holds the barrel in alignment with the firearm receiver and secures the barrel against rotational movement during installation of a barrel nut or similar device. The fixture may be configured to work with the legacy AR15/M16 type barrel nut, as well as other designs as disclosed herein.
