I've never owned a Kreiger barrel so earlier this year, I asked Manzella Precision in Montana to machine me up a pre fit for my Rim X.
While I was waiting for it to arrive, I found another Kreiger blank at the SARA store in Adelaide. I had them send it directly to Rolf Hey in Hobart and Rolf fitted it to my Bergara B14R.
Both packages arrived within days of each other recently.
I set them up and have done a couple of range sessions. Both rifles function as they should.
Quality 22LR ammo is non existent in my area these days (and has been for some time) so I've only used anything I have on hand to do my initial tests.
No 20X5's to post yet but I've seen enough to know that both barrels will shoot very accurately.
