I love my K31. Is a '43 issue with a beech stock and shoots the GP11 quite well.

I purchased a replacement mag and shot respectively at our service rifle matches.

It was a Cali range and the folks with registered pre-ban AR's ruled but I held my own against

Garands and Mausers and service rifles of like kind.

Was slightly bummed that the groups with the GP11 ammo were the nearly equivalent of the handloads in my favorite 30*06
that was scoped but I probably couldn't have come close in a hunting situation trying to find game in a hurry and close the deal.
