Ruger Mark II; 10x Precision barrel liner opinions?

I have a 5 1/2" blued Ruger Mark II pistol.  I was looking at 10x Precision's website, specifically at their match barrel liner/rebore option (starting at $195).    Any reviews/opinions of it for accuracy @ 25 /50 yards? Durability?

Other option is a Clark rebarrel ($150 for  Walther barrel blank, $150 for installation).  Accuracy @ 50 Yards?

Just another option. I have no idea what your best choice would be.

I would go with Alex or Sams(not sure if he does ruger liners) there is a American rifleman or shooting sports article about both Alex and Sams relining 41s

I had Alex line a 41 barrel.  The 41 used to keyhole at 50 ft.  Now it is superb. 

Is there real sign of poor accuracy from the MkII ?  It would take a super trigger job to take advantage of the liner.

Clark may have some take off barrels. Alex did my 41, same liner as a Hammerli. Excellent workmanship.

I've never heard anything but good about Alex Hamilton's lined barrels. Everyone says that they'll shoot. I had some work done by him eons ago and he was very honest, professional and courteous.
