Best Mosin Nagant Scope Mount? Good Mosin Scope Mount?
The most frequent question I see among new Mosin Nagant rifle owners is which Mosin scope mount is best.
Here are a few good options, along with when it might be best to choose each.
Gear Report has thoroughly tested the Rock Solid Industries M-24-C Mosin Nagant scope mount and the M9130 M9159 Go Low™ Scout Scope Mount model MN9130GLM-M on our Mosin Modernization Project (link) rifles. We have others in the queue to give more thorough feedback soon. In the mean time, some observations from our experience thus far and from other mosin scope base options on the market:
- Rock Solid Industries (RSI) produces the most solid mosin nagant scope mounts we have found (when installed properly). If you want a mount that will not move even when bumped, then the solid, one-piece Rock Solid Ind. scope mounts are a good option. RSI scope mounts have no parts to slip or wiggle. However, they do require the rifle receiver be drilled and tapped as part of the installation. Install a Rock Solid Industries scope mount properly and it should never move. You can easily remove a RSI scope mount from your Mosin Nagant rifle. However, the mounting screw holes are hard to get rid of once drilled and tapped. I suppose you could weld them closed and refinish the receiver, but I would consider that overkill. *Update: August 2016 – In the picture to the right you see the M-24-C mount on our Mosin Modernization Project Sniper build. This mount was fantastic at first, but the gunsmith must not have put threadlocker on the installation of adjustment screws, as they ALL have worked their way loose more than once. Do yourself a favor and put threadlocker on all of the screws when you install the RSI scope mount.
- Choose a long scope mount like the RSI M-24-C if you will put multiple optics or devices on your rifle. For example, a magnified optic at the rear, over the ejection port, so that you can get proper eye relief, and a laser, flashlight or clip-on Night Vision device in front of the scope. There really is no substitute for the additional real estate of the long M-24-C scope mount.
- The M-24-C, or any other mount that puts your scope over the ejection port will require the mosin bolt handle be modified so that it will clear the scope. It also blocks the use of stripper clips for loading. Rock Solid Industries installed bent bolt handles on our two Mosin Modernization Project rifles and they feel fantastic.
- Choose a shorter scope mount like the RSI Scout Scope mount if you plan to use a long eye relief scope that will be mounted forward of the ejection port. A mosin scout scope does not require a bent bolt.
Brass Stacker‘s M9130 M9159 Go Low™ Scout Scope Mount model MN9130GLM-M requires that the rear sight base be removed from the Mosin Nagant rifle’s dovetail. Many folks are able to do this at home with no issues, although some sight bases are secured by pins that prove rather difficult to remove (some pins and sight bases are soldered, so you have to heat them with a torch to melt the solder before you can drive the pins out and remove the base). Once the M9130 M9159 Go Low™ Scout Scope Mount is installed, there are 2 hex screws securing the rail to the scope mount base. These allow the rail’s lateral alignment to be adjusted if the dovetail alignment is a bit off. The M9130 M9159 Go Low™ Scout Scope Mount does NOT require that your rifle receiver be drilled or tapped. If you think you might ever want to return your Mosin Nagant rifle back to original form, then the M9130 M9159 Go Low™ Scout Scope Mount might be a good choice since no holes or permanent modifications to the rifle are required for installation.
Choose a shorter scope mount like the M9130 M9159 Go Low™ Scout Scope Mount model MN9130GLM-M if you plan to use a long eye relief scope that will be mounted forward of the ejection port. A mosin scout scope does not require a bent bolt. We are using the Brass Stacker M9130 M9159 Go Low™ Scout Scope Mount model MN9130GLM-M with a NCStar SSB27522G supplied by Brass Stacker (they stressed this is the ONLY NCStar product that they recommend).
Brass Stacker also offers mounts for different configurations:
- Brass Stacker MN384453SSM Scout Scope Mount for Mosin Nagant M38, M44 and T53 Rifles
- MN9130SSM Scout Scope Mount for Mosin Nagant Rifles (mounts on top of the existing rear sight, with no removal of the site base)
- Universal Fit Brass StackerTM “Anchor Point” Series Scout Scope Mount for RUSSIAN Mosin Nagant M39, M9130, M38, M44, M53 Rifles.
- JMECKS Scope Mount for Mosin Nagant Rifles offers an option to Mosin shooters who prefer not to drill their receiver to install a scope mount, and allows use of iron sights. JMECKS sent a scope mount for which is in our review queue. The JMECKS mount uses a band to attach the scope mount to the Mosin Nagant rifle, similar to the method used to attach the rear sight to the Chinese T53 Mosin Nagant variant. JMecks sent us a scope mount to test and it is in our review queue. Expect a full review in the future. *August 2016 update: This mount has been waiting on our next build, which has been repeatedly delayed by a stock maker that has been on-again, off-again several times on whether they are sending a stock. I am quite frustrated and looking for other stock options so this build can progress.
- One might choose the JMECKS mount if you like the no drilling installation of the Brass Stacker, but wish to retain use of the iron sights.
- AND… JMECKS is one of the few manufacturers that will sell overseas and ship for a reasonable cost. Shipping to the UK, for example, is $26.95 , US Postal priority international.
- TrueShot Technologies See Through Scope Mount allows use of the original iron sights on the Mosin Nagant rifle. TrueShot committed to send a review sample over a year ago, but it has yet to arrive. We will update when/if it arrives and has been tested. Having no direct experience with the TrueShot Technologies Mosin scope mount I can only attest to seeing various heated arguments between supporters of RSI and TrueShot on some online forums. It appears both have passionate and loyal followings.
- One might choose a see through scope mount if you prefer to retain use of your iron sights while also using an optic on your Mosin Nagant. However, understand that see through scope mounts are usually taller. A taller see through sight base will raise your optic further above the bore axis of your barrel. Adjust your point of aim accordingly when sighting your optic.
- ATI Mosin Nagant Scope Mount Kit is another that we haven’t tried, but were asked to include by readers. While we have had success with other ATI products, we have heard nothing but bad things about the ATI Mosin Scope Mount kit. On the plus side, the kit is designed to be installed by the customer and includes a bent bolt handle. However, given the reputation of this product for poor tolerances and durability, we can not recommend it at this time. Since we prefer only to review products that we expect to like, I am not sure if I even care to ask ATI for a review sample. Please let us know in the comments if you have experience with the ATI mosin scope mount or ATI mosin bolt handle.
- Leapers UTG Mosin Scope Mount offers both the top rail as all other scopes listed here, but also 2 side rails for accessories. Installation is via the two pins in the rear scope base with no drilling. We have not tested this mount and can give no further feedback at this time.
We have shot with both the RSI and Brass Stacker mosin scope mounts and found both to work very well. If you care to purchase your Mosin Scope Mount through a trusted firearms retailer, then check out the Mosin Mounts offered by Brownells (link).
While there are also some cheaper options available online via eBay or Amazon, we have gotten enough bad feedback that we don’t trust most of them.
