Hey there Terry -- Welcome to Marlin Owners. I don't know if it's cause for worry, but it would bug me. I see it as either the sight base or the barrel dovetail is off. I would contact Marlin, and include the above picture, and request they replace the sight for starters. If that doesn't eliminate the gap, I'd go with a BCS. http://www.marlinowners.com/forum/cutting-dovetail/50125-shimming-sight-dovetail.html Hope this helps. Best regards. Wind

 

I contacted Marlin's Canadian warranty repair depot about the poor fit of the sight dovetail. they sent me a new rear sight.
It fit the same as the original very loose in the dovetail.
Last night I cut a piece of .008" brass shim stock to fit the bottom of the dovetail and epoxied and clamped it in place.
Tonight I carefully filed it until it would just start in the dovetail. After a couple tries I was able to get it to where it took
a light tap with a small hammer and a brass punch to get installed. I am very happy with the fit.
You should not have to do this with a new rifle.

I agree you should not have to fix anything on your NEW rifle. That being said, I'd knock that out and replace it with a Skinner Sight..

 

x2 on a Skinner. They can also sell you a dovetail blank insert.

 

Hi
Having problems with the rear sight on my new 1894 .45
I have tried tapping it with a small nylon hammer and used piece of wood as a drift and hit it harder, it just won’t move. Does anyone have any ideas?

 

Sorry about the typo 1894 .44

Brass punch, and a bigger hammer. Clamp it in a padded vise so all the hammer power goes into the sight base. I use a four ounce ball peen but go bigger if I have to. If it's to tight remove a small amount of metal from the BOTTOM of the sight base with a fine file. Go slow and test fit. Don't have to remove much!!

I also recommend the Skinner sights!!

 

Welcome to the forum. Glad you got it figured out and fixed. You shouldn't have had that problem with a new gun.

 

This is not a Ruger built new rifle. The rifle pictured is a Remington model. You cannot send it back to Ruger as Ruger will not accept repairs on rifles made by JM or Remington. There are only three 1895s currently in production by Ruger and only the GBL has a rear sight dovetail that is used. The TSBL has a receiver mounted Skinner and the SBL is a rail.

The repair you accomplished sounds like a good result and will work well.
