I've used an Axis 223 rifle for a build....did OK. Shoot with a gent who is prone to rebarrel factory rifles. Guess he's done at least 4 Axis rebarrels. Factory trigger leaves a lot to be desired, so it'll need work or replacement. Both of us have had little problem breaking free the barrel from the Axis action and removing it. However, both of us had a heck of a time removing the barrel nut from the barrel.....due to the darn beads stuck in the threads. If I ever rebarrel another Axis, I'll have a new barrel nut handy to use.
