Tang sight on a marlin?

[#57]

I found a tang sight and want to put it on a marlin 94. but that is where marlin put its serial #s. How do I get around this? Do I make a riser thats longer than the #? or does the serial need to be visable? I want to keep this legal for Cowboy Action Shooting also, so a reciver sight is out. Has anyone else been this route before? thanks all #57

#57, The tang sight I put on my Marlin (Lyman #2) came with a spacer block that had three holes in it. The rear hole accepted a new longer screw (#55 tang screw) supplied with the sight that went through the sight, through the spacer and screwed into the bottom. The center hole is a countersunk hole that you need to transfer and drill into the rear portion of the receiver tang. This new tapped hole will be in back of the serial number so you don't mess up the number. The front hole in the spacer is a taped hole that you use to tighten the sight down with.

The problem I had when I mounted it was that I bought the tang sight with no windage adjustment and unless everything is perfect aligning the front and rear sight can be troublesome. All the screws that mount the tang sight are the countersunk style and center where they want any allow no lateral movement.

I eventually went to an external screw with washers so I could nudge the sight into alignment. I also needed to fabricate a new rear tang screw (needed to be longer) with a special Marlin thread. The rear tang screw has a 32 threads per inch thread but it's not a standard diameter. It's a .201x32unfs.

Hope this helps. ppkny

Thanks, for your reply. Im having trouble visualising this as my SN takes up most of the space from the stock screw to the spur on the cocked hammer. there is a short space between the hammer and the sn but it would be covered when the hammer is cocked. any chance you have a pic or rember who made the adapter so I could get a pic from them. Thanks again #57

Oh, Thanks . I found it on the Lyman site. I may want to rethink this a little as I was reading the install instructions and found that I also need to mount it far enough back to allow for the bolt not to interfear with the sight. this puts my sight right in the middle of my grip. other than having to make all windage changes with the front sight how do you like the Lyman #2? #57.

#57, Here's a picture of my setup. The front screw goes into the spacer. The middle screw, underneath the sight, goes through the spacer into a taped hole you need to put in the receiver yoke. The rear screw goes through the sight through the spacer and is screwed into the bottom of the receiver yoke.
If you went with the standard installation all the screws would be flush and countersunk into the top of the sight. I customized mine to allow movement.
If you try to get aligmnet to the target by using the front sight only and if you have to move it so it's off center with the gun to much this will cause problems with aligning at short and long distances. That's why it's best to keep the front as close as possible to dead center.
As far as like it, yes. It gives you a much greater site radius and increased my accuracy. You need to alter your gripe on the stock when you shoot with the tang on bynot putting yout thumb over the stock but reasting it on the side. you'll get used to this.
Hoep this helps.

Does anyone know or can they compare the Marble to the Lyman? For silhouette I had been using a Marlin Cowboy so it was already tapped for the Lyman sight on the side. This I like but a friend wants to get started and their Marlin has not been tapped on the side. Should they go with the tang sight or the get the side tapped?

Suggestions would be appreciated.

Thanks in advance.

I started out with a receiver sight on the Marlin 357 I have but found that because it was the short barrel model 18.5 inches I wasn't getting enough sighting radius. Being so short and with the rear sight on the receiver it made the sighting radius to critical.
I went to the tang sight for one reason and that was to increase this distance. Some of my friends who have longer guns prefer the receiver sight mount and don't have the sighting radius problem.
