On Mosin Nagant dovetail mounted scout scopes, what back up rear sight if scope fails

[Hang Fire]

Many today are removing the Mosin Nagant rear sight and utilizing the existing dovetail for mounting scout scopes. But if scope fails, what backup sights are available?

Did a search for dovetail mounted rear sights and found these, was surprised at how low cost they are and look to be quality.

These are made for airguns, but they are very sturdy. Would have to be, for some airguns have a subtle, but vicious recoil that have ruined many a scope. Almost all reviews read were very positive.

Mendoza Micrometer open rear sight, +/- 20 bucks, says will fit 11 mm or 3/8” dovetail

They also make an aperture for around 30 bucks

I was going to order the open rear, but thinking maybe the aperture sight with the disc removed, might make a good ghost ring alternative.

Here is a cheap but "destructive" way, although cocking pieces are not that expensive:

How would you plan on getting the rear sight base off easily in the field
if the scope fails?

I like the sights that the guy added, but I would have added a sleeve over
the rear stud just for appearance sake, plus a jam nut on the bottom. Maybe
a piece of rubber vacuum line, which would compress to adjust.

I used this 3/8"/11 mm (adjustable for either)_dovetail to Weaver, it attaches to the MN dovetail with two SH cap screws. so removing the mount is simple. If one was using dovetail scope rings, that too would be simple to remove scope. For either, just slide the pre zeroed metal sight onto dove tail and tighten in place.

Got 11 mm dovetail to weaver mount installed on the MN dovetail, very pleased with it.

This is the full dog set screw which comes threaded into mount and prevents sliding under recoil.

I milled shallow recess in MN dovetail to accept the full dog set screw, very much doubt there will be any movement of the mount as some have suggested would take place under recoil.

You learn something every day, if you pay attention.

I really didn't knwo that there was a nice dovetail under that rear sight on the M-Ns.

Great looking mount, amazing price.

The dovetail does not exist on all MN, the M44 does not have it, but think all 91/30s do.

Think around 1941, Izhevsk and Tula started pinning the rear sight to the dovetail, but Tula dropped the practice afer a few months and continued to soft solder the sight to dovetail. To remove sight with the Izhevsk, drift out the two pins, sometimes a little solder was applied, and the pins are very hard to get out, but with a little heat they come easy.

On my Tula shown, the sight was soldered and had a small set screw in rear of sight base with slotted head. When tried screw driver, the slot just twisted out, milled it out, applied a little heat until soft solder flowed and sight pushed right off to the front. While area was still hot, wiped the remaining solder off, then used steel wool to remove the tinned effect.
