Sakoluvr,
Since Marlin's closing in 2011 finding a 98% 336 "Sporter Carbine" is your lucky day. Buy the rifle for it's 98% condition as MOST marlins were/are meat guns with years of use showing on wood and metal.
In my opinion, the 3/4 tube Marlins shoot much better than the full tube magazine rifles and require very little bedding tinkering to cut down the group sizes. All my Marlin rifles are 3/4 tube guns for a reason.
