I have a k31 that bubba re-worked the stock for me. My buddy at work wants me to turn it into an F-class rig for him. In return I get a Tikka tac rig, hum, he's got to buy the parts. I'll post it when complete. My personal K31icon, shoots 1.5" @ 100 yards doing my part. I think hand loads could bring that down a bit-SDH
