Preacherman,
You won't be disapointed. The first thing I do when I get a Marlin lever gun is an action job, a cross block safety removal, a decelerator pad and a set of ghost ring sights.
A word for the wise my friend. If you want a Marlin that really shoots do your self this little favor. When you inspect the bore look for these two tell tale accuracy killers.
1. If you can see any deformation at the muzzel end due to a too deep a cut front sight dove tail, pass on that particular gun. Not all Marlins have this defect but some do. And it's a sign that the gun is going to be a "BLACK marble" as they say.
2. And this is more important for you as you will be shortening your gun and the and losing the old front dove tail anyway.
When looking down your barrel with a good light look at the place on the inside of the barrel opposite the area that all the lettering is stamped on the outside of the barrel. If you even think that you see any bulging inward from an over press on the lettering, pass on that particular rifle. Believe it or not you will occasionally find one with an inward bulged barrel especially on the octagonal barrels.
3. With all that being said, Marlin has cleaned up there act on the octagonal barrels with the 45-70 cowboy. These decfects were down right common on the 1895 carbine limited rifles.
If your rifle has a goog clean barrel it should shoot like the dickens. Good luck and keep us informed..
