Randy68,
Where may I ask did you get what looks like aftermarket furniture for your Marlin? I might buy a 336c in need of a face lift. I'm guessing Boyds maybe?
Yes it came from Boyds and took some minor fitting but wasn't bad. This is a 1955 model with Ballard rifling that I had cerakoted and I cut the barrel down to 18". Makes for a mighty fine compact deer killer. Since I hunt next to state property I use cut down brass to make it legal in case I shoot one on there. There is no difference in accuracy between my regular and cut down rounds with the same load.
