    So my Mosin is shipping real soon and I'm excited to meet her. While I don't expect superb accuracy, I would like "minute of pie-plate" from her. Just for the sake of tightening up the groups, I'm considering adding an inexpensive scope.

    I'm considering the S&K mounts with a cheap red dot scope (midwayusa.com/product/459296/millett-compact-red-dot-sight-1-tube-1x-3-moa-dot-with-weaver-style-rings-matte) as demonstrated in the Nutnfancy video on youtube.

    I'm also considering the BrassStacker mount with a BSA Edge pistol scope (midwayusa.com/product/461634/bsa-edge-pistol-scope-2x-20mm-duplex-reticle-matte)

    I like that the BrassStacker allows me the option of switching to irons if I want to, but I'm not particularly keen on the look of a big rail.

    Any other suggestions/ideas?

    Thanks,

    P

    On the cheap i would just pick up a set of windage adjustable .22 rings and use the rail under the rear sight to mount a pistol scope.

    Everyone seems to leave out the PSO-1 side-mount option.
    It is really easy to install and use, and it is by far my favorite sighting device for the MN. The best part is, it still allows for the use of the iron sights.

    Below is my personal Nagant, and it shoots like a champ with the Romanian LPS Tip-2 scope calibrated for the 150gr surplus ammo. Soda bottles are in one-shot danger out to 250 yards, at least. Never had a chance to shoot further.

    Be aware though, you will have to bend your bolt which isn't too hard if you have access to a welder, a flat file and a round file.

    A lot of people have no idea about the 12mm dovetail under the rear sight.

    This Weaver to dovetail mount is ten bucks:

    For another 20 or 30 dollars can have an open or aperture rear sight with target adj knobs that mounts on the same dovetail:

    war squirrel,thats awsome,never thought of this before or seen it. sorta a no brainer since MN guns don't have good mount spots.

    BTW,you quote from Chrono is sweet,still play that classic to this day!

    I had no idea. That makes things a whole lot simpler though!

    Thanks for the mount ideas.

    Any preferred inexpensive scopes/red dots?

    Though for air guns, (brutal air gun recoil has ruined many a good scope) these items are very well made and stongly built. I have had mounted for a while and the MN recoil has had no effect on them.

    To my knowledge only the 91/30 has the dovetail, I know the Model 44 carbine as a rule does not.

    On the 91/30 there is almost always a slotted screw seen in sight base which was used to locate the sight on dovetail prior to pinning or soldering in place. When attempting to remove, this screw will likely shear off or break and have to be drilled out for sight base removal.

    The Izzy rear sight will have two pins (+ sometimes a bit of soft solder) which need to be drifted out. But on a Tula like mine, the sight was secured on the dovetail by soft solder only and I had to apply propane torch heat to get solder to flow for drifting sight off.

    There are videos on Youtube about removing MN rear sight base and scope mounting on dovetail

    Open sight: http://www.pyramydair.com/s/a/Mendoza_Micrometer_Sight_11mm_Dovetail/2004

    Aperture sight: http://www.pyramydair.com/s/a/Mendoza_Diopter_Sight_11mm_Dovetail/2003

    Weaver to dovetail mount (current price $8.74) : http://www.amazon.com/UTG-11mm-Weaver-Adapter-Adjustable/dp/B001CJ67E6/ref=pd_sim_sbs_sg_1 It is adustable for either 3/8'” or 11mm dovetail. Note the dog set screw stop at top rear of mount. This is why I milled (or easily drilled) a shallow recess in MN dovetail to prevent mount movement from recoil.

    With the diopter disk removed, makes for a great out on the barrel ghost ring sight. The eye automatically seeks center same as on a receiver mounted aperture sight.

    Here are some videos on removing the MN rear sight base. First video is on a M44 which had pins, second video is on a Tula which also had pins. So, so much for the rules I stated in my other post, looks like pinned or not, will depend on the individual rifle you may have.

    Most refer to the dovetail as being 3/8” (0.375”) but the one on my Tula is 12mm (0.4724”). The mount I bought is adjustable from 3/8” to 11mm (0.4331”) and it fits fine on the 12mm dovetail, so I do not know if a 3/8” only will work or not.

    A word of warning: Mosins have been known to kill cheap scopes and red dots.

    I agree turtlefish, i put a 80 doller scope on a mosin. After a case of ammo, it wouldnt hold zero.

    Any medium-price-range, recoil-rated scope should do the job. Maybe one of Leupold's lower-end pistol scopes on a scout mount?

    Nope, their rear sight base is a sleeve that's pinned on.

    Thought so, I seen a pin, but I thought it was for something internal (leaf-spring).

    hang fire, I am interested in that dovetail notch rear sight as I was just looking earlier today for a windage and elevation adjustable rear sight for the Mosin Nagant with repeatable adjustments, but in your picture it looks like you have a modified front sight, will that sight work with a regular front sight? Also are they click adjustable?

    When I bought, it was prebubbarized as in photo and someone had put a Lyman ramp/bead on it, but OEM front sight should work the same. As stated, I removed rear sight base and scout scoped it &c.

    Yes, the open and aperture sights shown are click (can feel, but not very loud though) and scale adjustable with target knobs.

    Not always true, I thought so too, but some M44 carbine rear sights were dovetailed and pinned or soldered. Same for the Tula, almost all the rear sight bases are soft soldered on the dovetail only, but there are some pinned exceptions.

    I am coming to learn never say always and never about the MN, for OEM variations will pop up and debunk those always and never thoughts.

    The baddest of the bad (firearm) scope killer I know of are springer air rifles. Their reverse recoil is most unkind to firearm scopes.

    lps scope optino for mosin

    i saw your pic of the lps scope on the mosin and was curious why you have the scope so low to the body. from every thing i've seen of the placement of lps/Pso scopes on their original rifles they were meant to be be sat higher up over the receiver. Or am I just looking at things wrong?
