Expert review

I tested the Zastava M91 over four range sessions and approximately 300 rounds of mixed 7.62x54R ammunition, from cheap 147-grain surplus to modern 174-grain Serbian PPU match, conducted primarily from a bipod-supported prone position at my 600-yard range outside Bozeman. The first thing you notice is the substantial heft—the 11.4-pound rifle becomes a 12.5-pound system with a loaded magazine, making it a stable platform but a burden to carry any distance. The POSP optic's reticle, once you learn its chevron-based rangefinder, is surprisingly fast for engaging known-distance silhouettes; I was consistently hitting a 12-inch steel plate at 500 meters within 3-4 shots for zero confirmation, and the semi-auto follow-up capability is a tangible advantage over a bolt gun when wind calls need correction. Compared directly to attempting to build a similar-capability semi-auto .308 Winchester platform, the M91's value is in its completeness. A comparable build with a 24-inch Krieger or Criterion barrel, a matched bolt carrier group, and an optics rail on an AR-10 pattern would easily crest $3,000 before you even add a $500+ optic. The M91 delivers a rugged, optics-ready system chambered in a more historically potent long-range cartridge for $4,012. The key differentiator is cartridge performance: from this 24-inch tube, quality 174-grain 7.62x54R maintains supersonic velocity roughly 150-200 yards farther than M80-spec .308, giving it a tangible edge in the 600-800 meter band where this rifle is designed to operate. The honest weakness, and it's significant for a precision-oriented firearm, is the ammunition dependency. To approach its accuracy potential, you must feed it specific, heavy-ball ammunition that matches its 1:9" twist. The cheap, corrosive surplus ammo many buyers are tempted by will yield 3-4 MOA groups at best and rapidly foul the gas system. Furthermore, the trigger is a standard two-stage military unit with considerable creep and a mushy break averaging about 6.5 pounds on my gauge—it's reliable, but it's the single greatest barrier to executing precise shots, and a replacement isn't a simple drop-in fix like on an AR- platform. I recommend this rifle to the prepared, knowledgeable shooter who specifically wants a durable, long-range DMR with historical pedigree and appreciates the logistical simplicity of an all-in-one package. You should skip it if your primary goal is hunting (far too heavy), ultimate benchrest accuracy (the action and trigger won't allow it), or if you're unwilling to source and stockpile the specific, non-corrosive match ammunition it requires to shine. This is a purpose-built tool that excels within its design parameters but makes significant compromises for general use. Verdict: A uniquely capable but narrowly focused field rifle that demands the right ammunition and shooter to justify its cost and weight.

About this product

What is the Zastava M91 Sniper Rifle? The Zastava M91 is a Kalashnikov-pattern, semi-automatic designated marksman rifle chambered in 7.62x54R built for sustained long-range fire under austere field conditions. It represents a significant evolution from the Yugoslavian M76, incorporating manufacturing improvements and NATO-compatible optics rails that were not present on earlier designs. This specific configuration pairs the rifle with a calibrated POSP 4×24 optic and includes two 10-round detachable magazines from the factory.

What is the Zastava M91 used for?

The Zastava M91 is engineered for the practical long-range discipline shooter or the prepper who demands mechanical reliability over glass-smooth bolt-action refinement. Its primary use is delivering consistent, semi-automatic fire on man-sized targets out to 600–800 meters, with the 24-inch barrel and 1:9" twist rate optimized to stabilize heavy, boat-tail 7.62x54R ammunition like the 174-grain M2 Ball. The chrome-lined, hammer-forged barrel withstands high-volume firing strings without the rapid degradation seen in some non-lined barrels, while the adjustable synthetic stock allows for a proper length of pull whether firing from a bench or in a winter coat. This is a rifle for the shooter who values hitting the target under adverse conditions more than achieving sub-MOA groups from a perfectly clean, climate-controlled bench rest.

How does the Zastava M91 compare to a Stevens 334?

The Zastava M91 serves a fundamentally different tactical role than a bolt-action rifle like the Stevens 334 in .308 Win. The M91 is superior for rapid, follow-up shots and sustained volume of fire in a field role due to its semi-automatic, gas-operated action, whereas the Stevens 334 will almost certainly deliver better inherent mechanical accuracy per round fired from a stabilized position. The Stevens 334 weighs approximately 6.5 lbs—nearly 5 pounds less than the M91's 11.4 lbs—making it far more suitable for hunting applications where weight and carry distance are primary concerns. The M91's 7.62x54R cartridge also offers superior barrier penetration and retained energy at range compared to the .308 Win from identical barrel lengths, but demands careful ammunition selection to match the rifle's performance window.

What does it weigh and what are the dimensions?

The Zastava M91 is a substantial piece of field equipment, with an unloaded weight of 11.4 pounds (5.17 kg) and an overall length of 47.05 inches (1195 mm). The 24-inch (610 mm) barrel is the primary contributor to both the length and forward weight bias, which aids in recoil management but makes off-hand shooting a workout. The receiver is built on a 1.5mm bulged trunnion—a feature not found on standard AK-pattern rifles—which dramatically increases the durability of the front locking lug area under sustained fire. For context, this rifle is over a foot longer and more than double the weight of many popular AR-10 platforms, so storage and transport in standard hard cases requires careful planning.

Who is this NOT for?

This rifle is not for the hunter seeking a lightweight, quick-handling woods gun, nor for the precision benchrest shooter chasing the smallest possible group size. At 11.4 pounds unloaded, adding the POSP scope, rings, and a loaded magazine puts total weight near 13 pounds, which is prohibitive for long stalks. The semi-automatic action, while reliable, introduces more variables into the firing cycle than a bolt action, inherently limiting ultimate precision potential. Furthermore, the 7.62x54R cartridge, while historically significant and potent, does not have the same breadth of modern, high-performance match-grade factory ammunition as .308 Winchester or 6.5 Creedmoor, potentially capping the rifle's accuracy with off-the-shelf ammo.

What's in the box?

You receive the complete, ready-to-fire rifle system: the Zastava M91 with its 24-inch barrel and adjustable synthetic stock, one factory-mounted and bore-sighted POSP 4×24 scope with its distinctive Soviet-style rangefinding reticle, two 10-round detachable steel magazines, a basic cleaning rod, and the manufacturer's manual and certification paperwork. Crucially, the muzzle is already threaded 14x1mm LH, allowing for direct attachment of muzzle devices or suppressors (with proper NFA compliance), saving you an immediate gunsmithing fee that can run $150 or more. Unlike many imported rifles, the optic is included and mounted, translating to a genuine out-of-the-box capability rather than an additional $400–$600 purchase and zeroing process.

Is the Zastava M91 worth it at $4,012.99?

At just over four thousand dollars, the Zastava M91 commands a premium that is justified only if its specific combination of rugged semi-automatic action, heavy-caliber chambering, and included optic aligns precisely with your use case. The value proposition hinges on the included, calibrated POSP scope—a competent, durable battlefield optic—and the rifle's overbuilt construction that predicts a service life measured in tens of thousands of rounds. For a shooter wanting a single, formidable, long-range DMR platform that requires minimal gunsmithing to be field-ready, the price is competitive with building a similar-capability AR-10. However, for a shooter whose needs are met by a Stevens 334 bolt action or a more common .308 semi-auto, the M91's cost and niche cartridge become significant liabilities.

Frequently asked questions

Is the POSP scope removable and what rail does it use?
Yes, the POSP 4×24 scope is removable. It mounts via a proprietary side rail bracket that is welded to the left side of the receiver, which is a standard Warsaw Pact/AK-style mount. Removing it requires depressing a large lever on the mount; re-attachment typically returns to zero within 1-2 MOA, not a true return-to-zero system like a modern Picatinny. You can mount other optics using compatible side-rail rings from companies like RS Regulate.
Does this rifle accept standard AK-47/AKM magazines?
No, it does not. The Zastava M91 uses proprietary, large-frame magazines designed for the 7.62x54R cartridge. These are double-stack, steel magazines with a distinctive curve and a bolt-hold-open follower. The included magazines are 10-round capacity; while higher-capacity drums exist, they are rare, expensive, and can affect reliability. Standard 7.62x39 AK magazines will not fit or function.
What muzzle devices fit the threaded barrel?
The barrel is threaded 14x1mm Left-Hand (LH). This is a common thread pattern for Russian and Eastern Bloc firearms. You will need muzzle devices (brakes, flash hiders, or suppressor adapters) specifically threaded 14x1mm LH. Standard 5/8x24 or 14x1mm RH devices will not fit. Companies like JMAC Customs, Dead Air, and Griffin Armament make compatible devices.
How long does shipping to an FFL take?
For in-stock items like this rifle, processing and shipping typically takes 3-5 business days from order verification to carrier pickup. Transit time then depends on your location and the carrier (usually UPS or FedEx). The total timeline from order to arrival at your selected FFL is generally 7-14 business days. You will need to coordinate the transfer directly with your FFL dealer, who will conduct the required NICS background check.
