No need to stick to pitted and time-worn wood, aftermarket Mosin-Nagant stocks abound and are the fast lane to enhancing the iconic rifle.
What Are The Top Aftermarket Mosin-Nagant Stocks:
- Editor's Choice: KPYK (Crook) Chassis
- Best Budget: ATI Monte Carlo Stock
- Best For Precision: ProMag Archangel OPFOR
- Best For Hunting: Boyd’s At-One
Given its long and storied history, playing the aftermarket game with a Mosin-Nagant is sacrilege to some. It’s difficult to argue their logic. Would you tinker with a vintage M1 Garand or a working order M1908A1? Best to leave these old warhorses alone and ticking like they always have.
That said, the Mosin-Nagant poses a different proposition. With over 37 million rifles built over the years, there are still plenty of rough specimens available today and we don't think that anyone should shed a tear over one of these being modified. There are some rare and collectible variants out there too that should probably be left alone, but run-of-the-mill 91/30s are not that. The good news for anyone looking to upgrade their warhorse is that despite its length of tooth, there are a few good options to help dial the bolt-action closer to contemporary performance expectations.
Original Mosin-Nagant stocks aren’t exactly a thing of beauty. Their aesthetics fit with those of a mud fence. And as to performance, let’s simply say they weren’t exactly designed to enhance the average Russian or Soviet soldier’s innate marksmanship. An extremely linear stock, with a straight grip and a metal buttplate, does not a pleasurable shooter make. Plus, it feels just shy of a T-34 tank in the weight department.
Much of this is easily solved. While the selection isn’t as extensive as it is for the Remington 700, there are plenty of solid aftermarket Mosin-Nagant stocks to tailor the rifle to your particular application. If we’ve piqued your interest, then you’ll want to continue reading, because we’ve gathered together four of the best Mosin-Nagant stocks to help turn your Russian iron into a tack driver, hunter or whatever you can think up for it.
How We Made Our Picks
Truth be told, there aren't that many aftermarket Mosin-Nagant stocks out there. The four featured on this list are the most popular on the market partly because there aren't many more to pick from. That said, we've handled all of these models and believe that each has virtues that could make them an excellent choice for different tasks. Whether your goal is bagging game, punching tight groups in paper or just replacing that rotten wood stock on your Mosin before it falls off, one of these should serve you well.
Best Mosin-Nagant Stocks:
KPYK (Crook) Chassis
Pros
- Chassis system w/ adjustable LOP and comb height
- Plenty of rail space for optics/accessories
- Can accept AR grips and stocks
- Adds detachable magazine
Cons
- Expensive
- Heavy
- KPYK is going out of business
There isn’t a wealth of Mosin-Nagant chassis options on the market, which makes the KPYK (pronounced “Crook” which means raven) variation worth its weight in gold. Released in 2015, the Ukrainian-made chassis is compatible with nearly every variation of the Russian rifle and is solidly built.
Manufactured from 7021 aluminum, the chassis has a fully adjustable buttstock, giving you plenty of play in comb rise and length of pull. The buttstock is also replaceable, given the threads are identical to those of a mil-spec AR-15 buffer. Additionally, the forearm boasts ample M-Lok slots, so dolling up your Mosin with the latest accessories is a snap. Honestly, these alone are well worth the price of entry, but there are a few other intriguing aspects of the KPYK Chassis.
V-Block bedding gives complete contact along the action, no matter if it’s octagonal or rounded. Further, the system allows for the use of detachable box magazines. Thankfully it uses Archangel/ProMag-pattern mags so you won't need to track down anything more expensive or proprietary. It also comes with three Picatinny rail sections, making optics mounting a snap. Finally, the KPYK Chassis is a drop-in installation, which might just be the best feature of all.
A brief note, KYPK is going out of business. As the time of this update the company was still around, but likely will shutter in 2025 unless something drastic changes. If you like this chassis there's no time to lose in getting one. MSRP: $539.95 ; Site: kpykusa.com

ATI Monte Carlo Stock
Pros
- Lightweight
- Classic hunting rifle look
- Durable material
- Affordable
Cons
- Not great for precision
- Lacking extra features
The original and most common chambering of the Mosin-Nagant is 7.62x54R, which is a dandy hunting round despite its age. It’s ballistically similar to the .30-06 Springfield. Yet, in its stock configuration, the Russian bang stick isn’t the most wieldy field rifle. ATI changes this in a snap with its Monte Carlo Mosin-Nagant stock.
Giving the rifle a classic hunter look and feel, it also does a number on its heft and manageability. This is thanks to its glass-reinforced polymer construction, which not only cuts down on weight, but is impervious to most environmental factors.
ATI bills the unit as compatible with most Mosin variations, and as a drop-in installation. Though, the latter might not always prove the case. To truly achieve the desired fit, there may be some material removal/addition required.
This is a straight polymer stock. Perhaps this might not matter to someone looking for a dedicated hunting upgrade or a range toy, but it will have plenty of flex under recoil which means it might not be the first choice for a long-range Mosin build. This may not be the most feature-rich option, but it's relatively affordable and still offers several advantages over an original wood stock. MSRP: $129.99 ; Site: atioutdoors.com

ProMag Archangel OPFOR
Pros
- Good for precision
- Adjustable LOP and comb height
- Adds detachable magazine
- Goose-neck grip
Cons
- Doesn't come with sling swivels or rails for mounting accessories
When it comes to precision builds, the Archangel has been the top choice among Mosin-Nagant stocks. For a long time that was a default position, since it was about the only precision option in the game. Even with other accuracy-enhancing stocks now in the running, we think there are still several reasons to consider the Archangel.
With carbon fiber- and glass-reinforced polymer, the Archangel is fully adjustable and conveniently so. Both length of pull and comb height are dialed in via thumbwheels, each with around 1 inch of play. Additionally, the stock has a goose-neck style grip with an ambidextrous palm swell. Precision rifle stocks have been trending towards pistol grips and away from traditional straight grips for some time now, so we think this is a particularly smart feature if precision is your goal.
Nice as the ergonomics are, what’s happening in the stock might be of more value in accurizing your Mosin. The Archangel features steel pillar bedding blocks, ensuring there is little to no wiggle once the action is in place. Furthermore, the system free-floats the barrel, making sure it has the pristine harmonics required to improve accuracy.
Finally, Russian-made Mosin-Nagants—any variation—are simple drop-in installs, but Finnish models may require a bit of finagling. Also, did we mention it makes the Mosin compatible with 5- and 10-round detachable box magazines? ProMag proprietary, but a nice upgrade nonetheless, especially if you're like me and hate the Mosin's clunky stripper clips. MSRP: $185.99 ; Site: www.promagindustries.com

Boyds At-One
Pros
- Adjustable LOP and comb height
- Good for precision
- Handsome wood
- Lightweight
- Very configurable/customizable
Cons
- Wood is less durable than synthetics
Honestly, if you have a favorite Boyds stock, disregard this particular pick. Given their advanced manufacturing system, nearly any of its stocks are compatible with a majority of common Mosin-Nagant models. That said, it’s difficult to look much further than Boyds' At-One Stock.
Among the most flexible systems available today, it takes the Mosin-Nagant to another level. And it’s not just the fully adjustable comb riser and length of pull we’re talking about. Though, push-button controlled, those are nice. But everything, from grip to forend and swivel points is either interchangeable or factory configurable to your needs.
Furthermore, Boyd’s hardwood laminates—what the stocks are constructed of—provide a good deal of the needed rigidity to improve the rifle’s accuracy. Not to mention, they’re eye-catching.
At 3 pounds, the At-One is light enough to keep a build field ready. At the same time, it is more than capable of providing the base for a precision rifle. MSRP: $249 ; Site: www.boydsgunstocks.com
