EABCO Barrels Thoughts?

Does anyone have experience with E Arthur Brown Company barrels?
I have the opportunity to trade for a CZ 457 action on a EABCO match 22 barrel in an MDT XRS chassis that’s supposedly never been shot.
I’m a lefty but I would be looking to put my daughter behind it in a couple years when she is big enough to handle the weight in a PRS 22 match.

I have never shot one of their barrels. Only thing I’ve ever bought from them is little plastic sabots for the 300 win mag.
