I have one on an AR, so I already know I like it , and want to put one on a Henry .44 but I'm unsure what length rail I'll need. It is 8" long, has 5" of eye relief and the eyepiece is 2.1" long and 1.4" high.

The Talley/Henry mount seems too tall for this little scope. The Ashley Emerson mount looks fantastic but is for Marlins (4 mounting screws vs 3 for the Henry). This isn't a scout scope so I don't need or want an extended rail. I'd really like to be able to keep my rear sight, so with low QD Leupold rings I can pull the scope and use the irons.

These are the rails I'm looking at. The Skinner looks just a hair lower but the regular RPP rail will let me see the irons with the scope removed, the longer version seems to also have that ability and might be the length I need.

The rear of the rifle's receiver to the rear of the rear sight is just over 6". From mocking up the scope and using a ruler I think I can put the scope just forward of the hammer, thus avoiding a hammer extension, and still have good eye relief. The top of the rear sight seems like it might protrude about a third of an inch into the scope but the rail and the rings also might put the scope just over it. If I have to ditch the rear sight it's not the end of the world, I can use a Skinner dovetail sight as they're shorter than the factory rear sight.

Here's Leupold's low 1" scope rings-

This is a picture of a 2.5 in the Ashley mount on a Marlin 1894 (same length receiver) for reference. Henry rear sights are closer to the receiver, about 2 inches off.



Any thoughts? I've never put a scope on a levergun before so of course the first one I do is a tricky bastard.

I was an early adopter of the marlin GG.  Tried some different glass on their factory weaver rail.  The Eotech holo went flying, rail snapped right off.   I hope they are using a bigger screw now, but mine were 6- something.
Got the stubs extracted.  Tiny screws.  I was shooting near top end handloads .  Yeah I don’t need that horsepower for elk.
Dialed those back a lot.

My first attempt, and it came out perfectly.  I drilled the holes in the receiver larger and tapped in 8-32 I think
Ordered the lowest rail from brownells, measured 3x and drilled it out.

I like the 2x for elk.  45/70 stops them quick.

If I change anything I’ll swap rails too.  That’s a weaver and I have moved to pic on everything else.  Might even get it a bit lower.

I still needed a bit of stock rise so there is 3/4” of rise to get a good cheek weld.
Plus the thing was battering my cheek, soft smack now.
Anything but factory irons will have you coming off the stock a bit, at least with mine.

Either of those linked rails look like an excellent option.

If life was easy nobody would quit.

Excellent, thank you! Two questions if I may-

-what rings are those?
-5 or 6 inch rail?

If you are asking me, I think that is 9”.  I cut it from blank rail.  Use pic rail if you go that way.

The rings are leo. QD.  Very old and very good.  That’s 1” tho, most stuff is 30mm anymore.

I like the low Leupold QD rings, for me it's a case of having both options open.  The ghost ring plus my scope.

America is at that awkward stage, it’s too late to work within the system, but too early to shoot the bastards....Claire Wolfe

Thanks guys! I only have just over 6" between the end of the receiver and the rear sight. I think I'll go with the 6" RPP rail and a cheap set of Amazon rings to see where I need to be, then later get the appropriate Leupold QDs. 👍
Amazon has the Leupold Rifleman rings for 25 bucks, they're probably not enough for this gun (1 top screw on each side) but it'll show me if everything fits and I can use them on a .22 afterwards.
