I bought one used about 10 years ago and sent it to Connecticut Precision Chambering for a K chambering job, bolt shim replacement, trigger job, and target crown. The total bill was $225.00 The trigger now breaks clean at 2 1/2 lbs, and the gun shoots 1" groups while fireforming with WW 46gr HP's. I haven't even worked up a K load with it yet. Love the gun, and love the work that CPC did to it.
