I vote for the K-31 for several reasons. One they are just plain cool. Second the action is very smooth. Third the trigger is awesome. Forth they are cheap, Century just had and is going to have another 3 for $207 deal. Fifth they are said to be VERY accurate. Needless to say I have one on the way. I missed the last 3 fer deal and just ordered one from someplace else.
One drawback is ammo is expensive but it is easy to reload for. They shoot .308 cal. bullets.
