I wouldn't hesitate to purchase a Lilja barrel. I've met Mr. Lilja...at his shop. He spent the time to give us a tour of his shop and describe how he makes barrels. I would venture a guess that his barrels are of equal quality of the other top names.
Good Luck,
Wayne
If you were looking to replace your .25 cal barrel...I could hook you up with a stainless fluted Lilja with a Vais brake on it....but see you're looking for a 6.5mm.
