Best Mosin Scope Mount?

[CaveMike]

I bought a 91/30 Mosin sporter project that someone else started and that I'm going to finish. There are quite a few different options for scoping these rifles and I haven't really seen one yet that I much care for, so I figured that I'd ask here. I plan on using the rifle for hunting as well as shooting at the range, so durability is key, and something I can install myself would be a plus as well. As I've seen it so far, there are pretty much two options:

#1-forward style mount, usually replacing the rear sight, and requiring a long eye relief scope, or pistol scope. If I did go this way, which mount and scope combo have people been happy with.

#2-Rear scope mount, allowing for normal eye relief scope, and but requiring modified bolt. If I go this way, which scope mount and which bolt mod service should I use. Ease of install, durability, and being able to easily load the rifle are all important. Some of the mounts I've seen look pretty crappy, and some look like they'd really make it difficult to actually load the rifle.

(I'm not interested in the do it yourself turned down bolt, if I go this route I'll have it done properly.)

Thanks in advance!

i have heard good thngs from multiple sources about the brass stacker mount used with a "pistol scope" (ie long eye relief)

The Brass Stacker mount is very solid and installs easily on most Mosins (with the exception of those that had the pins soldered). Make sure you get a scope that can stand up to some recoil...avoid the $40 Chinese jobs; they won't last or hold zero on a Mosin. Weaver makes some good options in LER scopes for around $200.

#1: Brass Stacker scout mount
#2: Talk to 6mmintl here on the forums about one of his PU side mounts that takes standard scope rings.

I have a cheap NcStar long eye relief scope mounted directly on the rear sight dovetail. Works perfect and doesn't move. I tried one of those ATI scope mounts that replace the rear flip up sight and it was a joke. Take the whole sight block off and use the dovetail if you are going that route.

this might sound weird, but I don't really shoot well with scopes, especially long-eye-relief types, so if you are awkward with them a scout type setup may not be for you. I did this on a '91 argentine mauser I had and could never hit the frickin' ground with it. it shot well with the iron sights but I never could get the hang of that scout scope deal, just weird. I understand the rock solid mount is the best, although a good old weaver side-mount also works. that's what i'm putting on mine if I ever start working on it again.

Heard a lot of good things about Rock Solid mounts.

That rocksolid mount looks like it might be the ticket.

From personal experience, I've tried a few methods before finding one that worked.

If you've ever seen the lousy rail mount that you attach to the rear mount with one crummy pin, it won't hold. Never could get it to stay zeroed.

It looks something like this:


Later on I'd tried another one similar but had a securing bolt through the center. I tightened it up and thought it was good, but found it had the same problem.

This guy wound up being the ticket:



I think it's a 3/8ths (11mm) dovetail mount that you can bolt to the rear mount on the barrel after you remove the sight block by punching out the two securement pins. The stock will have to come apart if you go this route, but I found it totally worth the work. I wouldn't look at anything less then three screws to secure it for the kind of recoil the mosin has.

If you add a pistol scope with a long eye relief in something adjustable ( I went with a 2-7x40 ), you should be good to go.

Definitely not the ATI scope mount or anything else that requires permanent modification..

What's the brand name on the one that you chose to use?

I will steer clear of the ATI mount, but I am not afraid of permanent modification in this one rare case. This baby is never going back to stock form. It's too late. I bought a project that was already a little hacked up, so I can do whatever I want here, 100% guilt free! The barrel has already been cut and re crowned, the rifle is disassembled, and so on and so forth. Add to that the fact that I'm half retarded and even though I'm right handed, I shoot left handed! Who knows what I'm going to end up with here.

Shoot, can't remember for the life of me.

Link to the pic provided of what I have similar:

The trick is to not overtighten the screws. A little sanding on the inner rail, some mild loctite compund (blue), and the rail won't come loose. There are are plenty of others on there with just two screws, but three is always good insurance against any chance of movement.

There are also other variants online with fixed scope rings, but I imagine having versatility would be handy if you needed to change them out for something larger, smaller, or for something totally radical like an EOTech or a red dot.

Another type I'd seen while digging around is this:

http://www.ebay.com/itm/Scout-Scope-Mount-for-Mosin-Nagant-9130-See-Through-with-Picatinny-Rail-/281028845584?pt=LH_DefaultDomain_0&hash=item416e9fe010

It looks easier to install and cleaner while leaving the original rear sight block on. Just punch out the two pins, place on top, put the screws through, and tighten. I don't have any personal experience with it though.

It's also four times more.

Best of luck on a decision.

That's what I'm getting

One of our members here, 6mmintl , makes a nice PU style mount that allows you to use big modern optics. Get one of those and a current commercial production PU base from some place like Accumounts.

The PU type setup is the best scope mount available for Mosins. This is what people who really know Mosins - the Russians - devised and used on their final version of the Mosin sniper, as well as hunting and target/match rifles. Everything else is just turds floating in the bowl.

If you could find a decent one - it seems that most of the ones out there currently are Chinese crap - one of the copies of the earlier top-mount PE/PEM setup would also work. You would want one with the ring size that allows you to use a standard diameter modern scope.
