How does the Marlin .22 Lever action compare to the Henry?
Asking that question is like throwing a match into a gasoline can, but here's my own personal opinion on the matter having owned both rifles.
Firstly, as far as I'm concerned, Marlin hasn't existed since they were purchased by Remington. All of my opinions in that area are based on that fact. If you buy a Marlin, get a used one and get the oldest one you can find in decent condition. I think the Marlin 39A peaked in quality between around 1954 when they started using micro-groove rifling up through around the late 60's.
Both are American made if that matters to you.
Both are very accurate but the Marlin has a bit of an edge here.
The Henry has a smoother action when brand new, but a Marlin will smooth up considerably with some use. It will still have two distinct clicks as you work the lever each direction.
A used Marlin 39A in good condition will cost you more than a new Henry. On the other hand, a Marlin will appreciate in value but a Henry will never be worth more than it was when it was brand new.
Many people forget that a 39A is a takedown rifle. You can split the receiver in half to make for easier transportation and much easier cleaning.
Most Marlins you will find will have a pistol grip, though there have been small runs of a "Mountie" version with a straight stock and a shorter barrel. Jump on one of those if you see it.
The Marlin is made of steel and walnut, the Henry has a potmetal receiver and some plastic parts. Both are well built, but I have my doubts about whether the Henry will hold up as long. They haven't been around long enough to know if they'll still be shooting in 60 years, but I have no doubts that I'll be able to hand down my old Marlins to my kids, who can pass them down from there.
I'd buy another Henry for the right price if I wanted a rifle to bang around in the woods, keep in the truck, or as a first rifle for a youngster. They're good shooters and made at home. If I wanted an heirloom, it would be the Marlin over just about anything else.
And now it's time to sit back and watch the fireworks while everyone says that I'm just a Marlin snob.
