With the Marlin 25MN, you don't usually need to do much.
Nice, ain't it?
Added a sling. Locking in increases accuracy.
Center Point 4-16x40 scope...I like to hit critters in the noggin.
Rock Mount Bipod...self explainatory.
Stoned the trigger slightly, breaks at 2.9 pounds.
Pillar bedded the action.
Shoots ragged hole groups at 25 & 50, and at 75 if I'm having a good day, cloverleafs up to 125, and all in the bullseye at 150.
What more do you NEED????
